4 RULES FOR SAFE OPERA TION ⢠Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the sawâ s chain stops moving when the trigger is released. ⢠Use extreme caution when cutting small-sized brush and saplings because slender material may catch the chain saw and whip towards you or cause you to lose control. ⢠When cutting a limb that is under tension, be alert for springback so that you will not be struck when the ten- sion in the wood fibers is released ⢠Do not cut through nails, r ods in the tree, railr oad ties or pallets. Inspect a tree that you ar e going to cut for for- eign objects that could cause injury or damage to your chain saw . ⢠After striking a foreign object, stop the motor and thor- oughly inspect for damage. Repair as necessary . ⢠W e do not recommend using the chain saw in a tree or on a ladder . MAINT AIN YOUR SA W IN GOOD WORKING ORDER ⢠All chain saw service, other than the items listed in this instruction manual maintenance instructions, should be performed by a Sears or other qualified service dealer . ⢠Make sure all fasteners ar e in place and secure. ⢠Unauthorized replacement parts or the r emoval of safety devices may cause damage to the unit and possible injury to the operator or bystanders. Use only Craftsman accessories and replacement parts as r ecommended. Never modify your saw . ⢠When not in use, saw should be stored in a dry , highly secure location away fr om children. ⢠All chain saw service, other that the items listed in this instruction manual maintenance instructions, should be performed by a Sears or other qualified service dealer . ⢠Use the right tool. Only use this chain saw for its intend- ed purpose, to cut wood. ⢠Do not overreach. Always keep pr oper footing and bal- ance. ⢠Always hold the unit with both hands when operating. Keep a firm grip on all handles or grips. ⢠Apply chain brake prior to any repositioning of the oper- ator in the cutting area. As an additional safety pr ecau- tion, apply the chain brake prior to setting down the saw . ⢠Never touch the chain or attempt to service the saw while the motor is running. Make sure all moving parts have stopped. Allow the chain saw to cool, as the chain can be hot. ⢠Check the bar and chain at frequent intervals for pr oper adjustment. Make sure the bar and chain ar e properly tightened and sharpened. Visually inspect for damage. Repair any damage before r estarting or operating the chain saw . KICKBACK SAFETY PRECAUTIONS ⢠With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. Be alert to the potential for kickback at all times. ⢠Keep a good firm grip on the saw with both hands, the right hand on the rear handle and the left hand on the front handle, when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw han- dles. A firm grip will help you reduce kickback and main- tain control of the saw . Donât let go. ⢠Make sure that the ar ea in which you are cutting is fr ee from obstructions. Do not let the nose of the guide bar contact a log, branch, fence, or any other obstruction that could be hit while you are operating the saw . ⢠Always cut with the motor running at full speed. Fully squeeze the trigger and maintain a steady cutting speed. ⢠Use only the correct original equipment manufactur er replacement bars, chains and other parts and acces- sories. These are available fr om a Sears or other quali- fied service dealer . Use of any unauthorized parts or accessories could lead to serious injury to the user , or damage to the unit, and will void your warranty . ⢠Follow the manufacturerâ s sharpening and maintenance instructions for the saw chain. ⢠Use only the replacement guide bars and low kickback chains specified for your saw to avoid injury . ⢠W atch for shifting logs or other forces that could pinch or fall into chain. ⢠Always have saw at full speed when entering a previous cut. Always use caution when entering a previous cut. ⢠Do not start a cut using the tip of the saw . KICKBACK may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse r eaction, kicking the guide bar up and back towards the operator . Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator . Either of these reactions may cause you to lose contr ol of the saw , which could result in serious per- sonal injury . Do not rely exclusively upon the safety devices built into your saw . As a chain saw user , you should take several steps to keep your cutting jobs free fr om accident or injury . W ARNING:
5 OTHER SAFETY PRECAUTIONS ⢠Do not operate a chain saw with one hand! Serious injury to the operator , helpers, bystanders, or any com- bination of these persons may result fr om one-handed operation. A chain saw is intended for two-handed use. ⢠Do not operate a chain saw if you are fatigued. ⢠Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing, and head protection devices. ⢠Do not allow other persons to be near the chain saw when starting or cutting with the chain saw . Keep bystanders and animals out of the work area. ⢠Do not remove, damage or de-activate any of the safety devices. Never use a damaged, modified, or improperly repair ed or assembled chain saw . Check their proper operation regularly . See chain r eplacement under Maintenance and Repair Instructions. ⢠Never carry out operations or repairs on your own that are other than r outine maintenance as listed in this manual. ⢠Use caution when felling a tree. Make sur e you have planned an escape path when felling, and keep all bystanders away . ⢠Be alert; stop the machine if anyone enters the cutting area, which is usually 3 to 4 feet ar ound the operator . ⢠Use caution when working in a crew to avoid injury to a fellow worker who may enter the cutting area. ⢠Keep these instructions. Refer to them often and use them to instruct other users. If you loan this unit to oth- ers, also loan these instructions to them. ⢠Store the unit in a dry place, secur ed, or at a height to prevent unauthorized use or damage.

9 RULES FOR SAFE OPERA TION cont. KICKBACK SPECIFICS KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse r eaction, kicking the guide bar up and back toward the operator . Any of these reactions may cause you to lose contr ol of the saw , which could r esult in serious personal injury . Rotational Kickback Rotational Kickback can occur when the moving chain contacts an object at the upper tip of the guide bar . This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator . Kickback can lead to dangerous loss of control of the chain saw and r esult in serious or fatal injury to the saw operator or to any- one standing close by . Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents. W ARNING: KICKBACK SPECIFICS Pinch Kickback Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bar . When pinched on the bottom of the guide bar , it may pull the saw forward, away fr om the operator . When pinched along the top of the guide bar , it may push the guide bar rapidly back toward the operator .

10 ST ARTING/STOPPING INSTRUCTIONS Never operate the saw without the bar and chain properly installed. W ARNING: STOPPING INSTRUCTIONS The saw motor will automatically stop when the trigger is released. T o restart the motor , you will have to depr ess the LOCK/OFF button and squeeze the trigger . 1. NOTE: The saw chain requir es lubrication when in use to minimize friction with the guide bar . The oil tank holds 4.5 ozs of oil, enough to lubricate the chain for 12-15 minutes of sawing. W e r ecommend using Craftsman Bar and Chain Lubricant, which contains additives to reduce friction wear and r educe resin residue formations. NOTE: Y our chain saw is equipped with an Automatic Oiler system and is the ONL Y source of lubrication for the bar and chain. 2. Be certain the Chain Brake® is disengaged before starting unit (Fig. 4). Disengage it by pulling backward toward the motor . 3. Hook the extension cord to the extension cord r etainer (A) (Fig. 5) that is built into the rear handle. This will pr event the cord fr om pulling out of the handle. Double the exten- sion cord, about a foot fr om the end, and insert it through the hole at the end of the handle. Hook the loop formed by doubling the cord over the tab. Gently tug on the cor d to ensure that it is firmly r etained in the saws handle. Plug the receptacle end of the extension cor d into the toolâ s power supply cord. 4. Perform Chain Brake T est which is located in the Maintenance and Repair Instructions . 5. Grip the saw with both hands, left hand holding the front handle (DO NOT HOLD CHAIN BRAKE®) and the right hand holding the rear handle. Thumbs and fingers should encircle both handles (Fig. 6). 6. With your right thumb, push forward the LOCK/OFF but- ton (C) on the top of the rear handle, and at the same time squeeze the trigger . T o stop the saw , release the trigger (Fig. 7). NOTE: It is not necessary to maintain pressur e on the LOCK/OFF button once the trigger is squeezed and the motor is running. The LOCK/OFF button is a safety device to avoid accidental starting. ST AR TING INSTRUCTIONS The oil reservoir level should be frequently checked during operation to avoid starving the bar and chain of lubrication. CAUTION: Ensure the extension cord is of the pr oper size and type for your saw . W ARNING: Make sure the exten- sion cord does not come in contact with the guide bar and saw chain. W ARNING: Oil Cap Oil Reservoir Inspection Spot A C Fig. 3 Fig. 5 Fig. 4 Fig. 6 Fig. 7 Fill the oil reservoir with corr ect chain and bar oil (Fig. 3). Use a funnel, wipe up any spills and make sure no dirt gets into the tank.
11 OPERA TING INSTRUCTIONS A B Do not cut down a tree during high or changing winds or if there is a danger to property . Consult a tr ee professional.Do not cut down a tree if ther e is a danger of strik- ing utility wires; notify the utility company before making any cuts. W ARNING: FELLING Felling is the term for cutting down a tree. Small tr ees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Lar ger trees r equire notch cuts. Notch cuts determine the direction the tr ee will fall. NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts ar e made, consider the loca- tion of lar ger branches and natural lean of the tree to determine the way the tree will fall. A retr eat path (A) should be planned and cleared as necessary befor e cuts are started. The retr eat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Fig. 8. W ARNING: If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled. CAUTION: Fig. 8 Fig. 9 Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D) (Fig. 9). Start making the upper notch cut (C) on the side of the tree facing the felling dir ection (E). Be sure you don t make the lower cut too deep into the trunk(Fig. 9). The notch (C) should be deep enough to create a hinge (F) of sufficient width and str ength. The notch should be wide enough to direct the fall of the tr ee for as long as possible (Fig. 9). Never walk in front of a tree that has been notched. W ARNING: Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, contr ol over the felling direction is lost. Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will pr e- vent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sur e no bystanders have entered the range of the falling tr ee before you push it over . Before making the final cut, always recheck the area for bystanders, animals or obstacles. W ARNING: Make the felling cut (D) from the other side of the tr ee and 1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C) (Fig. 9). G H Fig. 10 Felling Cut: 1. Use wooden or plastic wedges (G) to prevent binding the bar or chain (H) in the cut. W edges also control felling (Fig. 10). 2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Fig. 11). As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, r emove saw from cut, stop motor , put chain saw down, and leave area along r etreat path (Fig. 8). W ARNING: Hinge
12 OPERA TING INSTRUCTIONS Fig. 11 A LIMBING Limbing a tree is the pr ocess of removing the branches from a fallen tr ee. Do not remove supporting limbs (A) until after the log is bucked (cut) into lengths (Fig. 12). Branches under tension should be cut from the bottom up to avoid binding the chain saw . BUCKING Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cut- ting on sloping ground. If possible, the log should be sup- ported so that the end to be cut off is not r esting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway thr ough the log and then make the undercut. This will pr event the log from pinching the bar and chain. Be car eful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain. Fig. 12 Fig. 13 Never cut tree limbs while standing on a tree trunk. W ARNING: When bucking on a slope, always stand on the uphill side. 1. Log supported along entire length: Cut fr om top (over- buck), being careful to avoid cutting into the gr ound (Fig. 13). 2. Log supported on one (1) end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 14). 3. Log supported on both ends: First, overbuck 1/3 diame- ter of log to avoid splintering. Second, underbuck to meet first cut and avoid pinching (Fig. 15). NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported. BUCKING USING A SAWHORSE For personal safety and ease of cutting, the correct posi- tion for vertical bucking is essential (Fig. 16). A. Hold the saw firmly with both hands and keep the saw to the right of your body while cutting. B. Keep the left arm as straight as possible. C. Keep weight on both feet. Fig. 16 Fig. 15 Fig. 14 A B C While the saw is cut- ting, be sure the chain and bar are being pr operly lubricated. CAUTION:

SAW CHAIN TENSION ADJUSTMENT Proper tension of saw chain is extr emely important and must be checked before starting, as well as during any cutting operation. T aking the time to make needed adjustments to the saw chain will result in impr oved cutting performance and pro- longed chain life. NOTE: A new chain and bar will need readjustment after as few as 5 cuts. This is normal during the break- in period, and the interval between future adjust- ments will lengthen quickly (Fig. 22). Always use protec- tive gloves when handling the saw chain. W ARNING: A C B Fig. 22 Fig. 23 NOTE: Make sure the Chain Brake® is disengaged. Disengage the Chain Brake® (D) by pulling it backward (Fig. 23). 1. T ensioning the chain can be accomplished with rela- tive ease. T urn knob (E) counter clockwise. Then turn ring (F) counter -clockwise to loosen chain or clockwise to tighten chain (Fig. 24). If saw chain is TOO LOOSE or TOO TIGHT , the sprocket, bar , chain, and crank- shaft bearings will wear more rapidly . Study Fig. 22 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). CAUTION: Fig. 24 MAINTENANCE AND REP AIR INSTRUCTIONS D E 2. After adjustment and while wearing heavy duty work gloves, move the saw chain back and forth on the guide bar to be sure the chain moves fr eely and is in proper mesh with spr ocket. NOTE: If the chain is difficult to rotate or if it binds on the guide bar , too much tension has been applied and must be adjusted as described in step 1. 3. While applying tension to the chain, hold the tip of the bar up and then tighten the knob (E). F 15
16 CHAIN AND BAR LUBRICA TION Adequate lubrication of the saw chain during cutting oper - ations is essential to minimize friction with the guide bar . Y our chain saw is equipped with an automatic oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. There is no flow adjustment. Y ou can check the oil reservoir level using the oil reservoir window (D) provided on the right side of the saw . The reservoir is full when oil is at the top of the window (Fig. 25). CHAIN BRAKE® / HAND GUARD This chain saw is equipped with chain brake/hand guard. The Hand Guard pr otects your left hand in the event it slips off the fr ont handle. Never starve the bar and chain of lubrica- tion oil. Running the saw DR Y or with TOO LITTLE OIL will decrease cutting ef ficiency , shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. T oo little is evi- denced by smoke or bar discoloration. CAUTION: A loose chain can jump off the bar while you are cutting, as well as wear the bar and chain. A chain that is too tight can damage the saw . Either situation, chain too loose or too tight, could cause serious personal injury . W ARNING: The Chain Brake® should not be used for starting and stopping the saw during normal operation CAUTION: MAINTENANCE AND REP AIR INSTRUCTIONS D Fig. 25 Fig. 27 The Chain Brake® is a safety feature which is activated if pressur e is applied against the guard or when, in the event of kickback, the operatorâ s hand strikes the lever . When the Chain Brake® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off. The purpose of the Chain Brake® is to reduce the possi- bility of injury due to kickback. The Chain Brake® cannot, however , pr ovide the measure of intended pr otection if the saw is carelessly operated. The Chain Brake® is disengaged (chain can move) when the brake is pulled back and locked. This is the normal running position (Fig. 26). NOTE: The saw chain stretches during use, particularly when it is new , and occasional adjustment will be needed. A new chain requir es more fr equent adjustment during the break-in period. This is nor- mal. See Section Saw Chain T ension Adjustment for instructions. Fig. 26 The Chain Brake® is engaged (chain cannot move) when the brake is in forward position (Fig. 27). NOTE: The motor will not start if the Chain Brake® is in the engaged position.
17 MAINTENANCE AND REP AIR INSTRUCTIONS If the chain and motor fail to stop when the Chain Brake® is engaged, take the saw to a Sears or other qualified service dealer . Do not use the saw if the Chain Brake® is not in proper working or der . W ARNING: CHAIN BRAKE® TEST Before cutting with your saw , the Chain Brake® should be tested as follows: A. Make sure the Chain Brake® is disengaged (Fig. 26). B. Place the saw on a firm, flat, dry surface that is clear of any debris. Do not let the saw come in contact with any objects. C. Plug the unit into the power source. D. Grasp the fr ont handle (not the Chain Brake®/Hand Guard Lever) with your left hand. Thumb and fingers should encircle the handle. E. Grasp the rear handle with your right hand. Thumb and fingers should encircle the handle. F . Slide the LOCK/OFF button with your right thumb. Squeeze the trigger with your index finger (Fig. 7). G. While the motor is running, activate the Chain Brake® by rolling your left hand forwar d against the lever . H. Chain and motor should stop abruptly . A cord that is hot to the touch is over- loaded.

W ARNING: Do not operate your chain saw in a wet or damp environment. Do not expose the saw to rain, snow or sleet. Moisture will cause short circuits. Replace or r epair any damaged or frayed extension cords befor e using your saw . Keep the cord away fr om the cutting area and position the cord so that it will not be caught on branches or other objects during cutting. W ARNING: EXTENSION CORDS When using an electric chain saw , plug it into the exten- sion cord only when you ar e ready to cut wood. Connect the extension cord to a 110/120 voltage outlet. Refer to the Electrical Safety W arnings section. DOUBLE INSULA TION WHEN SER VICING, USE ONL Y IDENTICAL REPLACE- MENT P ARTS. Information Do not use if the cord or plug is damaged. Y our appliance is double insulated to help protect against electric shock. Double insulation construction consists of 2 separate âlay- ersâ of electrical insulation. Appliances built with this insulation system are not intend- ed to be grounded. As a r esult, the extension cord used with your appliance can be plugged into any conventional 120 volt electrical outlet. Normal safety precautions must be observed when operat- ing an electrical appliance. The double insulation system is only for added protection against injury r esulting from a possible internal electrical insulation failure. In this double insulated appliance, 2 systems of insulation, instead of grounding, ar e provided. No gr ounding means is provided on a double insulated appliance, nor should a means for grounding be added to the appliance. No serv- iceable parts are inside.

Place switch in OFF position and unplug the power supply before the appliance is serviced, cleaned, or maintenance is performed. 2. Keep the air intake clean and air vents free of debris to avoid overheating the motor . 3. Clean with a damp sponge and mild soap. Do not squirt with a water hose or douse with water or other liquids. 4. Inspect the saw chain for pr oper tension before each use and frequently during cutting. Sharpen as r equired. Refer to the Chain Sharpening in Maintenance and Repair Instructions. 5. Clean the guide bar and bar pad to ensure fr ee path for oil. 6. No motor lubrication is necessary . The motor is equipped with lifetime lubricated bearings. 7. If the saw does not operate, turn switch to OFF posi- tion and disconnect the extension cord, first fr om the power supply , then from the saw . Check the power supply for blown fuses or tripped circuit br eakers. If it still does not operate, take the saw to a Sears or other qualified service dealer . NOTE: Do not attempt to repair saw yourself. No serviceable parts are inside.
18 Sprocket Tip Lubrication The Lube Gun (not included) is recommended for applying grease to the guide bar spr ocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of gr ease to the sprocket tip. The sprocket tip on your new saw has been pre-lubricated at the factory . Failur e to lubricate the guide bar sprocket tip as explained below will result in poor perform- ance and seizure, voiding the manufactur erâ s warranty . Lubrication of the sprocket tip is r ecom- mended after each saw use. Always thor- oughly clean guide bar sprocket tip befor e lubrication. CAUTION: Fig. 28 T o lubricate the sprocket tip: 1. Unplug the chain saw from the power sour ce. NOTE: It is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication can be done on the job. 2. Clean the guide bar sprocket tip. 3. Using the Lube Gun (optional), insert tip of lube gun into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig. 28). 4. Make sure that the Chain Brake® is deactivated. Rotate saw chain by hand. Repeat lubrication proce- dure until the entir e sprocket tip has been gr eased. GUIDE BAR MAINTENANCE Frequent lubrication of the guide bar is r equired. Pr oper maintenance of the guide bar , as explained in this section, is essential to keep your saw in good working condition. MAINTENANCE AND REP AIR INSTRUCTIONS Ensure that the power cord is dis- connected before performing any mainte- nance on your saw . W ARNING: Always use protective gloves when handling the saw chain. W ARNING: Maintenance Procedur es Most guide bar problems can be pr evented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily r esulting in uneven bar wear . As the bar wears unevenly , the rails widen, which may cause chain clatter and difficulty in making straight cuts. Insufficient guide bar lubrication and operating the saw with chain that is too tight will contribute to rapid bar wear . T o help minimize bar wear , the following guide bar mainte- nance procedur es are r ecommended: BAR WEAR - T urn guide bar frequently at r egular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar . BAR GROOVES (B) (Fig. 29)- Bar grooves (or rails which support and carry the chain) should be cleaned if saw has been used heavily or if saw chain appears dirty . Rails should always be cleaned every time saw chain is removed. OIL P ASSAGES (A) (Fig. 29)- Oil passages on the bar should be cleaned to ensure pr oper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil dischar ge hole. NOTE: The condition of the oil passages can be easily checked. If the passages are clear , the chain will automatically give off a spray of oil within seconds of starting the saw . Y our saw is equipped with an automatic oiler system. Cleaning Bar Rails 1. Remove sprocket cover , bar and chain. Refer to the Install the Guide Bar/Saw Chain section. 2. Using a scr ewdriver , putty knife, wire brush or other sim- ilar instrument, clear residue fr om the rails on the guide bar . This will keep the oil passages open to pr ovide proper lubrication to the bar and chain (Fig. 29). 3. Reinstall the bar , chain, spr ocket cover , tighten knob, and chain tension ring. See Section Install the Guide Bar / Saw Chain for more information. Fig. 29 A B
19 MAINTENANCE AND REP AIR INSTRUCTIONS Never have more than 3 links removed fr om a loop of chain. This could cause damage to the sprocket. W ARNING: Chain Lubrication Always make sure the automatic oiler system is working properly . Keep the oil r eservoir filled with a high quality Chain, Bar and Sprocket Oil. Adequate lubrication of the bar and chain during cutting oper- ations is essential to minimize friction with the guide bar . Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting ef fi- ciency , shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. T oo little oil is evidenced by smoke or bar discoloration. Chain Sharpening Chain sharpening requir es special tools to ensure that cut- ters are sharpened at the corr ect angle and depth. For the inexperienced chain saw user , we r ecommend that the saw chain be professionally sharpened by the near est Authorized Service Center . If you feel comfortable sharp- ening your own saw chain, special tools are available fr om your Authorized Service Center . CHAIN MAINTENANCE A low-kickback saw chain should always be used in con- junction with other kickback protection devices such as the Chain Brake®/Hand Guard furnished with your unit. Always use a replacement saw chain designed as âlow- kickbackâ or a saw chain which meets the low-kickback performance requir ements of ANSI (American National Standards Institute). A standard saw chain (a chain which does not have the kickback reducing guar d links) should only be used by an experienced professional chain saw operator . What is a Low-Kickback Saw Chain? A low-kickback saw chain is a chain which has met the kickback performance requir ements of ANSI B175.1. By keeping the Chain Brake® and saw chain in good working condition and correctly serviced as r ecommended in this manual, you will be able to maintain the safety sys- tem of your chain saw over the life of the product. Chain T ension Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar , but loose enough to be pulled around by hand. Breaking in a New Saw Chain A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly . Over a period of time, however , the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. T ake the saw to a Sears or other qualified service dealer . Unless you have experience and spe- cialized training for dealing with kickback (see Safety Precautions), always use a low- kickback saw chain, which significantly reduces the danger of kickback. Low-kick- back saw chain does not completely elimi- nate kickback. A low-kickback or âsafety chainâ, should never be regar ded as total protection against injury . W ARNING: Never remove, mod- ify or make inopera- tive any safety device furnished with your unit. The Chain Brake® / Hand Guard and low-kickback saw chain are major safety features pr ovided for your protection.

4 RULES FOR SAFE OPERA TION ⢠Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the sawâ s chain stops moving when the trigger is released. ⢠Use extreme caution when cutting small-sized brush and saplings because slender material may catch the chain saw and whip towards you or cause you to lose control. ⢠When cutting a limb that is under tension, be alert for springback so that you will not be struck when the ten- sion in the wood fibers is released ⢠Do not cut through nails, r ods in the tree, railr oad ties or pallets. Inspect a tree that you ar e going to cut for for- eign objects that could cause injury or damage to your chain saw . ⢠After striking a foreign object, stop the motor and thor- oughly inspect for damage. Repair as necessary . ⢠W e do not recommend using the chain saw in a tree or on a ladder . MAINT AIN YOUR SA W IN GOOD WORKING ORDER ⢠All chain saw service, other than the items listed in this instruction manual maintenance instructions, should be performed by a Sears or other qualified service dealer . ⢠Make sure all fasteners ar e in place and secure. ⢠Unauthorized replacement parts or the r emoval of safety devices may cause damage to the unit and possible injury to the operator or bystanders. Use only Craftsman accessories and replacement parts as r ecommended. Never modify your saw . ⢠When not in use, saw should be stored in a dry , highly secure location away fr om children. ⢠All chain saw service, other that the items listed in this instruction manual maintenance instructions, should be performed by a Sears or other qualified service dealer . ⢠Use the right tool. Only use this chain saw for its intend- ed purpose, to cut wood. ⢠Do not overreach. Always keep pr oper footing and bal- ance. ⢠Always hold the unit with both hands when operating. Keep a firm grip on all handles or grips. ⢠Apply chain brake prior to any repositioning of the oper- ator in the cutting area. As an additional safety pr ecau- tion, apply the chain brake prior to setting down the saw . ⢠Never touch the chain or attempt to service the saw while the motor is running. Make sure all moving parts have stopped. Allow the chain saw to cool, as the chain can be hot. ⢠Check the bar and chain at frequent intervals for pr oper adjustment. Make sure the bar and chain ar e properly tightened and sharpened. Visually inspect for damage. Repair any damage before r estarting or operating the chain saw . KICKBACK SAFETY PRECAUTIONS ⢠With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. Be alert to the potential for kickback at all times. ⢠Keep a good firm grip on the saw with both hands, the right hand on the rear handle and the left hand on the front handle, when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw han- dles. A firm grip will help you reduce kickback and main- tain control of the saw . Donât let go. ⢠Make sure that the ar ea in which you are cutting is fr ee from obstructions. Do not let the nose of the guide bar contact a log, branch, fence, or any other obstruction that could be hit while you are operating the saw . ⢠Always cut with the motor running at full speed. Fully squeeze the trigger and maintain a steady cutting speed. ⢠Use only the correct original equipment manufactur er replacement bars, chains and other parts and acces- sories. These are available fr om a Sears or other quali- fied service dealer . Use of any unauthorized parts or accessories could lead to serious injury to the user , or damage to the unit, and will void your warranty . ⢠Follow the manufacturerâ s sharpening and maintenance instructions for the saw chain. ⢠Use only the replacement guide bars and low kickback chains specified for your saw to avoid injury . ⢠W atch for shifting logs or other forces that could pinch or fall into chain. ⢠Always have saw at full speed when entering a previous cut. Always use caution when entering a previous cut. ⢠Do not start a cut using the tip of the saw . KICKBACK may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse r eaction, kicking the guide bar up and back towards the operator . Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator . Either of these reactions may cause you to lose contr ol of the saw , which could result in serious per- sonal injury . Do not rely exclusively upon the safety devices built into your saw . As a chain saw user , you should take several steps to keep your cutting jobs free fr om accident or injury . W ARNING:
5 OTHER SAFETY PRECAUTIONS ⢠Do not operate a chain saw with one hand! Serious injury to the operator , helpers, bystanders, or any com- bination of these persons may result fr om one-handed operation. A chain saw is intended for two-handed use. ⢠Do not operate a chain saw if you are fatigued. ⢠Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing, and head protection devices. ⢠Do not allow other persons to be near the chain saw when starting or cutting with the chain saw . Keep bystanders and animals out of the work area. ⢠Do not remove, damage or de-activate any of the safety devices. Never use a damaged, modified, or improperly repair ed or assembled chain saw . Check their proper operation regularly .

9 RULES FOR SAFE OPERA TION cont. KICKBACK SPECIFICS KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse r eaction, kicking the guide bar up and back toward the operator . Any of these reactions may cause you to lose contr ol of the saw , which could r esult in serious personal injury . Rotational Kickback Rotational Kickback can occur when the moving chain contacts an object at the upper tip of the guide bar . This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back toward the operator . Kickback can lead to dangerous loss of control of the chain saw and r esult in serious or fatal injury to the saw operator or to any- one standing close by . Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents. W ARNING: KICKBACK SPECIFICS Pinch Kickback Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bar . When pinched on the bottom of the guide bar , it may pull the saw forward, away fr om the operator . When pinched along the top of the guide bar , it may push the guide bar rapidly back toward the operator .

10 ST ARTING/STOPPING INSTRUCTIONS Never operate the saw without the bar and chain properly installed. W ARNING: STOPPING INSTRUCTIONS The saw motor will automatically stop when the trigger is released. T o restart the motor , you will have to depr ess the LOCK/OFF button and squeeze the trigger . 1. NOTE: The saw chain requir es lubrication when in use to minimize friction with the guide bar . The oil tank holds 4.5 ozs of oil, enough to lubricate the chain for 12-15 minutes of sawing. W e r ecommend using Craftsman Bar and Chain Lubricant, which contains additives to reduce friction wear and r educe resin residue formations. NOTE: Y our chain saw is equipped with an Automatic Oiler system and is the ONL Y source of lubrication for the bar and chain. 2. Be certain the Chain Brake® is disengaged before starting unit (Fig. 4). Disengage it by pulling backward toward the motor . 3. Hook the extension cord to the extension cord r etainer (A) (Fig. 5) that is built into the rear handle. This will pr event the cord fr om pulling out of the handle. Double the exten- sion cord, about a foot fr om the end, and insert it through the hole at the end of the handle. Hook the loop formed by doubling the cord over the tab. Gently tug on the cor d to ensure that it is firmly r etained in the saws handle. Plug the receptacle end of the extension cor d into the toolâ s power supply cord. 4. Perform Chain Brake T est which is located in the Maintenance and Repair Instructions . 5. Grip the saw with both hands, left hand holding the front handle (DO NOT HOLD CHAIN BRAKE®) and the right hand holding the rear handle. Thumbs and fingers should encircle both handles (Fig. 6). 6. With your right thumb, push forward the LOCK/OFF but- ton (C) on the top of the rear handle, and at the same time squeeze the trigger . T o stop the saw , release the trigger (Fig. 7). NOTE: It is not necessary to maintain pressur e on the LOCK/OFF button once the trigger is squeezed and the motor is running. The LOCK/OFF button is a safety device to avoid accidental starting. ST AR TING INSTRUCTIONS The oil reservoir level should be frequently checked during operation to avoid starving the bar and chain of lubrication. CAUTION: Ensure the extension cord is of the pr oper size and type for your saw . W ARNING: Make sure the exten- sion cord does not come in contact with the guide bar and saw chain. W ARNING: Oil Cap Oil Reservoir Inspection Spot A C Fig. 3 Fig. 5 Fig. 4 Fig. 6 Fig. 7 Fill the oil reservoir with corr ect chain and bar oil (Fig. 3). Use a funnel, wipe up any spills and make sure no dirt gets into the tank.
11 OPERA TING INSTRUCTIONS A B Do not cut down a tree during high or changing winds or if there is a danger to property . Consult a tr ee professional.Do not cut down a tree if ther e is a danger of strik- ing utility wires; notify the utility company before making any cuts. W ARNING: FELLING Felling is the term for cutting down a tree. Small tr ees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Lar ger trees r equire notch cuts. Notch cuts determine the direction the tr ee will fall. NOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts ar e made, consider the loca- tion of lar ger branches and natural lean of the tree to determine the way the tree will fall. A retr eat path (A) should be planned and cleared as necessary befor e cuts are started. The retr eat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Fig. 8. W ARNING: If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled. CAUTION: Fig. 8 Fig. 9 Normally felling consists of 2 main cutting operations, notching (C) and making the felling cut (D) (Fig. 9). Start making the upper notch cut (C) on the side of the tree facing the felling dir ection (E). Be sure you don t make the lower cut too deep into the trunk(Fig. 9). The notch (C) should be deep enough to create a hinge (F) of sufficient width and str ength. The notch should be wide enough to direct the fall of the tr ee for as long as possible (Fig. 9). Never walk in front of a tree that has been notched. W ARNING: Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, contr ol over the felling direction is lost. Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will pr e- vent the guidebar from binding in the felling cut if you have misjudged the falling direction. Make sur e no bystanders have entered the range of the falling tr ee before you push it over . Before making the final cut, always recheck the area for bystanders, animals or obstacles. W ARNING: Make the felling cut (D) from the other side of the tr ee and 1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C) (Fig. 9). G H Fig. 10 Felling Cut: 1. Use wooden or plastic wedges (G) to prevent binding the bar or chain (H) in the cut. W edges also control felling (Fig. 10). 2. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Fig. 11). As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, r emove saw from cut, stop motor , put chain saw down, and leave area along r etreat path (Fig. 8). W ARNING: Hinge
12 OPERA TING INSTRUCTIONS Fig. 11 A LIMBING Limbing a tree is the pr ocess of removing the branches from a fallen tr ee. Do not remove supporting limbs (A) until after the log is bucked (cut) into lengths (Fig. 12). Branches under tension should be cut from the bottom up to avoid binding the chain saw . BUCKING Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cut- ting on sloping ground. If possible, the log should be sup- ported so that the end to be cut off is not r esting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway thr ough the log and then make the undercut. This will pr event the log from pinching the bar and chain. Be car eful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain. Fig. 12 Fig. 13 Never cut tree limbs while standing on a tree trunk. W ARNING: When bucking on a slope, always stand on the uphill side. 1. Log supported along entire length: Cut fr om top (over- buck), being careful to avoid cutting into the gr ound (Fig. 13). 2. Log supported on one (1) end: First, cut from bottom (underbuck) 1/3 diameter of log to avoid splintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 14). 3. Log supported on both ends: First, overbuck 1/3 diame- ter of log to avoid splintering. Second, underbuck to meet first cut and avoid pinching (Fig. 15). NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb stumps or by using supporting logs. Be sure the log being cut is securely supported. BUCKING USING A SAWHORSE For personal safety and ease of cutting, the correct posi- tion for vertical bucking is essential (Fig. 16). A. Hold the saw firmly with both hands and keep the saw to the right of your body while cutting. B. Keep the left arm as straight as possible. C. Keep weight on both feet. Fig. 16 Fig. 15 Fig. 14 A B C While the saw is cut- ting, be sure the chain and bar are being pr operly lubricated. CAUTION:

SAW CHAIN TENSION ADJUSTMENT Proper tension of saw chain is extr emely important and must be checked before starting, as well as during any cutting operation. T aking the time to make needed adjustments to the saw chain will result in impr oved cutting performance and pro- longed chain life. NOTE: A new chain and bar will need readjustment after as few as 5 cuts. This is normal during the break- in period, and the interval between future adjust- ments will lengthen quickly (Fig. 22). Always use protec- tive gloves when handling the saw chain. W ARNING: A C B Fig. 22 Fig. 23 NOTE: Make sure the Chain Brake® is disengaged. Disengage the Chain Brake® (D) by pulling it backward (Fig. 23). 1. T ensioning the chain can be accomplished with rela- tive ease. T urn knob (E) counter clockwise. Then turn ring (F) counter -clockwise to loosen chain or clockwise to tighten chain (Fig. 24). If saw chain is TOO LOOSE or TOO TIGHT , the sprocket, bar , chain, and crank- shaft bearings will wear more rapidly . Study Fig. 22 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). CAUTION: Fig. 24 MAINTENANCE AND REP AIR INSTRUCTIONS D E 2. After adjustment and while wearing heavy duty work gloves, move the saw chain back and forth on the guide bar to be sure the chain moves fr eely and is in proper mesh with spr ocket. NOTE: If the chain is difficult to rotate or if it binds on the guide bar , too much tension has been applied and must be adjusted as described in step 1. 3. While applying tension to the chain, hold the tip of the bar up and then tighten the knob (E). F 15
16 CHAIN AND BAR LUBRICA TION Adequate lubrication of the saw chain during cutting oper - ations is essential to minimize friction with the guide bar . Y our chain saw is equipped with an automatic oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. There is no flow adjustment. Y ou can check the oil reservoir level using the oil reservoir window (D) provided on the right side of the saw . The reservoir is full when oil is at the top of the window (Fig. 25). CHAIN BRAKE® / HAND GUARD This chain saw is equipped with chain brake/hand guard. The Hand Guard pr otects your left hand in the event it slips off the fr ont handle. Never starve the bar and chain of lubrica- tion oil. Running the saw DR Y or with TOO LITTLE OIL will decrease cutting ef ficiency , shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. T oo little is evi- denced by smoke or bar discoloration. CAUTION: A loose chain can jump off the bar while you are cutting, as well as wear the bar and chain. A chain that is too tight can damage the saw . Either situation, chain too loose or too tight, could cause serious personal injury . W ARNING: The Chain Brake® should not be used for starting and stopping the saw during normal operation CAUTION: MAINTENANCE AND REP AIR INSTRUCTIONS D Fig. 25 Fig. 27 The Chain Brake® is a safety feature which is activated if pressur e is applied against the guard or when, in the event of kickback, the operatorâ s hand strikes the lever . When the Chain Brake® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off. The purpose of the Chain Brake® is to reduce the possi- bility of injury due to kickback. The Chain Brake® cannot, however , pr ovide the measure of intended pr otection if the saw is carelessly operated. The Chain Brake® is disengaged (chain can move) when the brake is pulled back and locked. This is the normal running position (Fig. 26). NOTE: The saw chain stretches during use, particularly when it is new , and occasional adjustment will be needed. A new chain requir es more fr equent adjustment during the break-in period. This is nor- mal. See Section Saw Chain T ension Adjustment for instructions. Fig. 26 The Chain Brake® is engaged (chain cannot move) when the brake is in forward position (Fig. 27). NOTE: The motor will not start if the Chain Brake® is in the engaged position.
17 MAINTENANCE AND REP AIR INSTRUCTIONS If the chain and motor fail to stop when the Chain Brake® is engaged, take the saw to a Sears or other qualified service dealer . Do not use the saw if the Chain Brake® is not in proper working or der . W ARNING: CHAIN BRAKE® TEST Before cutting with your saw , the Chain Brake® should be tested as follows: A. Make sure the Chain Brake® is disengaged (Fig. 26). B. Place the saw on a firm, flat, dry surface that is clear of any debris. Do not let the saw come in contact with any objects. C. Plug the unit into the power source. D. Grasp the fr ont handle (not the Chain Brake®/Hand Guard Lever) with your left hand. Thumb and fingers should encircle the handle. E. Grasp the rear handle with your right hand. Thumb and fingers should encircle the handle. F . Slide the LOCK/OFF button with your right thumb. Squeeze the trigger with your index finger (Fig. 7). G. While the motor is running, activate the Chain Brake® by rolling your left hand forwar d against the lever . H. Chain and motor should stop abruptly . A cord that is hot to the touch is over- loaded. CAUTION: Y our double insulat- ed appliance has no serviceable parts inside. Do not attempt to repair it yourself. For service information, take the saw to a Sears or other qualified service dealer . W ARNING: Do not operate your chain saw in a wet or damp environment. Do not expose the saw to rain, snow or sleet. Moisture will cause short circuits. Replace or r epair any damaged or frayed extension cords befor e using your saw . Keep the cord away fr om the cutting area and position the cord so that it will not be caught on branches or other objects during cutting. W ARNING: EXTENSION CORDS When using an electric chain saw , plug it into the exten- sion cord only when you ar e ready to cut wood. Connect the extension cord to a 110/120 voltage outlet. Refer to the Electrical Safety W arnings section. DOUBLE INSULA TION WHEN SER VICING, USE ONL Y IDENTICAL REPLACE- MENT P ARTS. Information Do not use if the cord or plug is damaged. Y our appliance is double insulated to help protect against electric shock. Double insulation construction consists of 2 separate âlay- ersâ of electrical insulation. Appliances built with this insulation system are not intend- ed to be grounded. As a r esult, the extension cord used with your appliance can be plugged into any conventional 120 volt electrical outlet. Normal safety precautions must be observed when operat- ing an electrical appliance. The double insulation system is only for added protection against injury r esulting from a possible internal electrical insulation failure. In this double insulated appliance, 2 systems of insulation, instead of grounding, ar e provided. No gr ounding means is provided on a double insulated appliance, nor should a means for grounding be added to the appliance. No serv- iceable parts are inside. A double insulated appliance is marked with the words, âDOUBLE INSULA TIONâ or âDOU- BLE INSULA TED.â The symbol (squar e within a square) may also be marked on the appliance. Maintenance 1. Place switch in OFF position and unplug the power supply before the appliance is serviced, cleaned, or maintenance is performed. 2. Keep the air intake clean and air vents free of debris to avoid overheating the motor . 3. Clean with a damp sponge and mild soap. Do not squirt with a water hose or douse with water or other liquids. 4. Inspect the saw chain for pr oper tension before each use and frequently during cutting. Sharpen as r equired. Refer to the Chain Sharpening in Maintenance and Repair Instructions. 5. Clean the guide bar and bar pad to ensure fr ee path for oil. 6. No motor lubrication is necessary . The motor is equipped with lifetime lubricated bearings. 7. If the saw does not operate, turn switch to OFF posi- tion and disconnect the extension cord, first fr om the power supply , then from the saw . Check the power supply for blown fuses or tripped circuit br eakers. If it still does not operate, take the saw to a Sears or other qualified service dealer . NOTE: Do not attempt to repair saw yourself. No serviceable parts are inside.
18 Sprocket Tip Lubrication The Lube Gun (not included) is recommended for applying grease to the guide bar spr ocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of gr ease to the sprocket tip. The sprocket tip on your new saw has been pre-lubricated at the factory . Failur e to lubricate the guide bar sprocket tip as explained below will result in poor perform- ance and seizure, voiding the manufactur erâ s warranty . Lubrication of the sprocket tip is r ecom- mended after each saw use. Always thor- oughly clean guide bar sprocket tip befor e lubrication. CAUTION: Fig. 28 T o lubricate the sprocket tip: 1. Unplug the chain saw from the power sour ce. NOTE: It is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication can be done on the job. 2. Clean the guide bar sprocket tip. 3. Using the Lube Gun (optional), insert tip of lube gun into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig. 28). 4. Make sure that the Chain Brake® is deactivated. Rotate saw chain by hand. Repeat lubrication proce- dure until the entir e sprocket tip has been gr eased. GUIDE BAR MAINTENANCE Frequent lubrication of the guide bar is r equired. Pr oper maintenance of the guide bar , as explained in this section, is essential to keep your saw in good working condition. MAINTENANCE AND REP AIR INSTRUCTIONS Ensure that the power cord is dis- connected before performing any mainte- nance on your saw . W ARNING: Always use protective gloves when handling the saw chain. W ARNING: Maintenance Procedur es Most guide bar problems can be pr evented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily r esulting in uneven bar wear . As the bar wears unevenly , the rails widen, which may cause chain clatter and difficulty in making straight cuts. Insufficient guide bar lubrication and operating the saw with chain that is too tight will contribute to rapid bar wear . T o help minimize bar wear , the following guide bar mainte- nance procedur es are r ecommended: BAR WEAR - T urn guide bar frequently at r egular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar . BAR GROOVES (B) (Fig. 29)- Bar grooves (or rails which support and carry the chain) should be cleaned if saw has been used heavily or if saw chain appears dirty . Rails should always be cleaned every time saw chain is removed. OIL P ASSAGES (A) (Fig. 29)- Oil passages on the bar should be cleaned to ensure pr oper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil dischar ge hole. NOTE: The condition of the oil passages can be easily checked. If the passages are clear , the chain will automatically give off a spray of oil within seconds of starting the saw . Y our saw is equipped with an automatic oiler system. Cleaning Bar Rails 1. Remove sprocket cover , bar and chain. Refer to the Install the Guide Bar/Saw Chain section. 2. Using a scr ewdriver , putty knife, wire brush or other sim- ilar instrument, clear residue fr om the rails on the guide bar . This will keep the oil passages open to pr ovide proper lubrication to the bar and chain (Fig. 29). 3. Reinstall the bar , chain, spr ocket cover , tighten knob, and chain tension ring. See Section Install the Guide Bar / Saw Chain for more information. Fig. 29 A B
19 MAINTENANCE AND REP AIR INSTRUCTIONS Never have more than 3 links removed fr om a loop of chain. This could cause damage to the sprocket. W ARNING: Chain Lubrication Always make sure the automatic oiler system is working properly . Keep the oil r eservoir filled with a high quality Chain, Bar and Sprocket Oil. Adequate lubrication of the bar and chain during cutting oper- ations is essential to minimize friction with the guide bar . Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting ef fi- ciency , shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. T oo little oil is evidenced by smoke or bar discoloration. Chain Sharpening Chain sharpening requir es special tools to ensure that cut- ters are sharpened at the corr ect angle and depth. For the inexperienced chain saw user , we r ecommend that the saw chain be professionally sharpened by the near est Authorized Service Center . If you feel comfortable sharp- ening your own saw chain, special tools are available fr om your Authorized Service Center . CHAIN MAINTENANCE A low-kickback saw chain should always be used in con- junction with other kickback protection devices such as the Chain Brake®/Hand Guard furnished with your unit. Always use a replacement saw chain designed as âlow- kickbackâ or a saw chain which meets the low-kickback performance requir ements of ANSI (American National Standards Institute). A standard saw chain (a chain which does not have the kickback reducing guar d links) should only be used by an experienced professional chain saw operator . What is a Low-Kickback Saw Chain? A low-kickback saw chain is a chain which has met the kickback performance requir ements of ANSI B175.1. By keeping the Chain Brake® and saw chain in good working condition and correctly serviced as r ecommended in this manual, you will be able to maintain the safety sys- tem of your chain saw over the life of the product. Chain T ension Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar , but loose enough to be pulled around by hand. Breaking in a New Saw Chain A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly . Over a period of time, however , the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. T ake the saw to a Sears or other qualified service dealer . Unless you have experience and spe- cialized training for dealing with kickback (see Safety Precautions), always use a low- kickback saw chain, which significantly reduces the danger of kickback. Low-kick- back saw chain does not completely elimi- nate kickback. A low-kickback or âsafety chainâ, should never be regar ded as total protection against injury . W ARNING: Never remove, mod- ify or make inopera- tive any safety device furnished with your unit. The Chain Brake® / Hand Guard and low-kickback saw chain are major safety features pr ovided for your protection.
