BECOME ALERT!!! YOUR SAFETY IS INVOLVED
,-. SAFETY RULES OPERATE YOUR SAW SAFELY ⢠Do not operate a chain saw with one hand. Serious injury to the operator, helpers, bystanders or any combina- tion of these persons may result from one-handed opera- tion. A chain saw is intended for two-handed use. ⢠Operate the chain saw only in well-ventilated outdoor areas. ⢠Do not operate saw from a ladder or in a tree, unless specifically trained to do so. ⢠Position all parts of your body to the left of cut and away from the chain when the engine is running. ⢠Cut wood only. Do not use your saw to pry or shove away limbs, roots, or other objects. ⢠Make sure the chain will not make contact with any object while starting the engine, Never try to start the saw when the guide bar is in a cut or kerr. ⢠Use extreme caution when cutting small size brush and saplings. Slender material can catch the chain and be whipped toward you or pull you off balance. ⢠Be alert for springback when cutting a limb that is under tension so you will not be struck by the limb or saw when the tension in the wood fibers is released. ⢠Do not put pressure on the saw at the end of a cut. Applying pressure can cause you to lose control when the cut is completed. ⢠Stop.the engine before setting the saw down. ⢠Keep fuel and oil caps, screws, and fasteners securely tightened. MAINTAIN YOUR SAW IN GOOD WORKING ORDER ⢠Have all chain saw service performed by your Sears Service Center with the exception of the items listed in the "Customer Responsibilities" section of this manual. For example, if improper tools are used to remove or ho{d the flywheel when servicing the clutch, structural damage to the flywheel can occur and cause the-flywheel to burst. ⢠Make certain the chain stops moving when the throttle trigger is released, For correction, refer to 'Carburetor Adjustments." ⢠Stop the saw if the chain strikes a foreign object. Inspect unit and repair or replace parts as necessary. ⢠Disconnect the spark plug before performing any maintenance except for carburetor adjustments. ⢠Never modify your saw in any way. Use only SEARS ' accessories and replacement parts as recommended. TRANSPORTING AND STORAGE ⢠Stop the unit before transporting. ⢠Allow engine to cool, cover the guide bar and chain, and secure the unit before storing or transporting in a vehicle. ⢠Empty fuel tank before storing or transporting the unit. Use up any fuel left in the carburetor by starting the engine and letting the engine run until it stops. ⢠Store unit and fuel in an area where fue! vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. ⢠Store unit so the chain cannot accidentally cause injury. ⢠Store the unit out of the r_ach of children. GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury. KICKBACK WARNING: KICKBACK CAN OCCUR WHEN THE MOV- ING CHAIN CONTACTS AN OBJECT ATTHE UPPER PORTION OFTHETIP OFTHE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE CHAIN IN THE CUT. CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR 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. IF THE CHAIN IS PINCHED ALONG THE TOP OF THE GUIDE BAR, THE GUIDE BAR CAN BE DRIVEN RAPIDLY BACK TOWARD THE OPERATOR. EITHER OFTHESE REACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. DO NOT RELY ONLY ON THE SAFETY DEVICES PROVIDED WITH YOUR SAW. AS A CHAIN SAW USER, YOU MUST TAKE SPECIAL SAFETY PRECAUTIONS TO HELP KEEP YOUR CUTTING JOBS FREE FROM ACCIDENT OR INJURY.

k SAFETY RULES "'2"; Ha ! Under Side Of _ Handlebar | Elbow _ Locked "'_ lstand t Of The Saw Figure 4 REDUCE THE CHANCE OF KICKBACK ⢠Recognize that kickback can happen. With a basic understanding of kicl_ack, you can reduce the element of surprise which contributes to accidents. * Never let the moving chain contact any object at the tip of the guide bar. Figure 2. . Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Figure 3. Eliminate or avoid any obstruction that your chain could hit while you are cutting through a particular log or branch. , Keep your chain sharp and properly tenaioned.A loose or dull chain can increase the chance of kickback to occur. Follow manufacturer's chain sharpening and maintenance instructions. Check tension at regular intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning the chain. ⢠Begin and continue cutting at full throttle. If the chain is moving at a slower speed, there is greater chance for kick- back to occur. ⢠Cut one log at a time. ⢠Use extreme caution when re-entering a previous cut. ⢠Do not attempt plunge cuts. ⢠Watch for shifting logs or other forces that could close a cut and pinch or fall into chain. ° Use the Reduced-Kickback Guide Bar and Low- Kickback Chain specked for your saw. KICKBACK SAFETY FEATURES _ WARNING: THE FOLLOWING FEATURES ARE INCLUDED ON YOUR SAW TO HELP REDUCE THE HAZ- ARD OF KICKBACK; HOWEVER, SUCH FEA- TURES WILL NOT TOTALLY ELIMINATE THIS DANGEROUS REACTION. AS A CHAIN SAW USER, DO NOT RELY ONLY ON SAFETY DEVICES. YOU MUST FOLLOW ALL SAFETY PRECAUTIONS, INSTRUCTIONS, AND MAIN- TENANCE IN THIS MANUAL TO HELP AVOID KICKBACK AND OTHER FORCESWHICH CAN RESULT IN SERIOUS INJURY. Reduced-Kickback Guide Bar, designed with a sma radius tip,which reduces the size of the kickback danger zone on me guioe par tip. Figure 5, A Reduced-Kickback Guide Bar is one which has been demonstrated to signif- icantly reduce the number and seriousness of kickbacks MAINTAIN CONTROL ⢠Keep a good, firm grip on the saw with both hands when the engine is running and don't let go. Figure 4. A firm grip can neutralize kickback and help you maintain control of the saw. Keep the fingers of your left hand encir- cling and your left thumb under the front handlebar. Keep your right hand completely around the rear handle whether you are right handed or left handed. Keep your left arm straight with the elbow locked, ⢠Position your left hand on the front handlebar so it is in a sl_aight line with your right hand on the rear harp die when making bucking cuts. Figure 4. Never reverse right and left hand positions for any type of cutting. ⢠Stand with your weight evenly balanced on both feel ⢠Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting chain. Figure 4. ⢠Do not overreach. You could be drawn or thrown off bal- ance and lose control of the saw. ⢠Do not cut above shoulder heighL It is difficult to main- tain control of saw above shoulder height. UNDERSTANDING REACTWE FORCES Pinch-Kickback and Puff-In occur when the chain is sud- denly stopped by being pinched, caught, or by contact- ing a foreign object in the wood.This stopping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite direction of the chain rotation. Either reaction can result in loss of control and pos- sible serious injury. ⢠Pinch-Kickback -occurs when chain on top of guide bar is suddenly stopped. - rapidly d/_ves saw straight back toward operator. ⢠PulHn - occurs when the chain on the bottom of the guide bar is suddenly stopped. - pulis the saw rapidly forward. inch displacement specified in ANSI B175.1-1991.

OPERATION . JP £:=?_ BEFORE STARTING ENGINE WARNING: BE SURE TO READ THE FUEL HANDLING INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF THIS MANUAL BEFORE YOU BEGIN. IF YOU DO NOT UNDERSTAND THE FUEL HANDLING SECTION DO NOT ATTEMPT TO FUEL YOUR UNIT; SEEK HELP FROM SOMEONETHAT DOES UNDERSTAND THE FUEL HANDLING SECTION OR CALL THE CUSTOMER ASSISTANCE HOTLINE AT 1-800-235-5878, GUIDE BAR AND CHAIN OIL For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. if Craftsman bar oil is not available, you may use a good grade SAE30 oil until you are able to obtain Craftsman brand, The oi! output is automati- cally metered during operation. Your saw will use approxi- mately one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank. GASOLINE The two-cycle engine on this product requires a fuel mixture of regular unleeded gasoline and a quality 40:1 2-cycle engine oi! (AIR-COOLED) for lubrication of the bear- ings and other moving parts. The correct fuel/oil mixture is 40:1 (see Fuel Mixture Chart).Too little oil orthe incorrect oil type will cause poor performance and may cause the engine to overheat and seize. Gasoline and oll must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. This engine is certified to operate on unleaded gasoline. IMPORTANT: Experience indicates that alcohol blended fuels called gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas separation and for- marion of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer, Drain the gas tank, then run the fuel out of the carburetor and fuel lines by starting the engine and letting it run until it stops. Use fresh fuel next season. See STORAGE instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. FUEL STABILIZER Fuel stabilizer is an acceptable a.ltemative in minimizing the formation of fuel gum deposits during storage. Add stabiliz- er to gasoline in fuel tank or storage container. Always fol- tow the fuel mix ratio found on the stabilizer container. Run engine at teast 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. You do not have to drain the fuel tank for storage if you are using fuel stabilizer. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended w_ fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank. 40:1 2-CYCLE AIR-COOLED ENGINE OIL CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)is strongly recommended. This oil is specifically blended with fuel stabilizers for increased fuel stability (extends fuel I_fe up to 5 times longer) and reduced smoke. If CRAFTSMAN 40:1 2-cycleengi_ne oil (AIR-COOLED).is not avellabie, use a good quality 2-cycle engine oil (AIR- COOLED) that has a recommended fuel mix ratio of 40:1. IMPORTANT! Do not use: ⢠AUTOMOTIVE OIL ⢠BOAT OILS (NMMA, BIA, etc.) These oils do not have proper additives for 2-cycle (AIR-COOLED) engines and can cause engine damage. GASOLINE AND OIL MIXTURE ⢠MIX GASOLINE AND OIL AS FOLLOWS: ⢠Consult chart for correct quantities. ⢠Do not mix gasoline and oil directly in the unit's fuel tank, FOR ONE GALLON: ⢠Pour 3,2 ounces of high quality, 40:1 2-cycle engine oil (AIR-COOLED) into an empty, approved one gallon gasoline container. ⢠Add one gallon of regular unleaded gasoline to the gallon container, then securely replace the cap. ⢠Shake the corttainet'momentadly. ⢠The mixture is now ready for use. Fuel stabilizer can be added at this time if desired; follow mixing instructions on the label FUEL MIXTURE CHART 40:1 Fuel:Oil Mix Ratio I _ Oil (fLoz.I 1 gallon 3.2 2.5 gallons 8.0 NOTE: Fuel containers may hold more than the specified amount. If too much gasoline is in the container, the result- ing gas-to-oil fuel mixture will not be correct for proper engine operation. -10-

⢠7 :i .... = OPERATION ,.,,, ,, ............ ii GENERAL OPERATION TIPS ⢠cut wood only. Do not cut metal; plastics; masonry; non- wood building materials; etc. ⢠Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or replace parts as necessary. ⢠Keep the chain out of dirt and sand. Even a sma!l amount of dirt will quickly dull a chain and thus increase the pos- sibility of kickback. To get the =feel" of using your saw before you begin a major sawing operation, practice cutting a few small Jogs using the following technique: ⢠Accelerate engine to full throttle by squeezing the throttle trigger before entering cut. ⢠Never cut with engine at partial speeds. ⢠Begin cutting with the saw chassis against the log. ⢠Keep engine at full throttle during cutting procedure. ⢠Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or engine can result. ⢠Release the throttle trigger as soon as the cut is com- pleted, allowing the engine to idle. If you run the unit at full throttle without cutting, unnecessary wear can occur to the chain, bar, and engine. ⢠To avoid losing control when completing the cut, do not put pressure on the saw during the end of the cut. ⢠Stop engine before setting unit down after operation. OPERATION SAFETY ,,i,,.Hi m Hi L i,H Hi = WARNING: IF SAW BECOMES PINCHED OR HUNG IN A LOG, DO Nor TRY TO FORCE IT OUT. YOU CAN LOSE CONTROL OF THE SAW RESULTING IN INJURY AND/OR DAMAGE TO THE SAW. STOP THE SAW, DRIVE A WEDGE OF PLASTIC OR WOOD INTO THE CUT UNTIL THE SAW CAN BE REMOVED EASILY. RESTARTTHE SAW AND CAREFUL- LY REENTER THE CUT. TO AVOID KICK- BACK AND CHAIN DAMAGE, DO NOT USE A METAL WEDGE. DO NOT ATTEMPT TO RESTART YOUR SAW WHEN IT IS PINCHED OR HUNG IN A LOG. KICKBACK CAN OCCUR WHEN THE MOV- ING CHAIN CONTACTS AN OBJECT AT THE UPPER PORTION OFTHETIP OFTHE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE SAW CHAIN IN THE CUT. CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR CAN CAUSE THE CHAINTO DIG INTOTHE OBJECT AND STOP THE CHAIN FOR AN INSTANT.THE RESULT IS A LIGHTNING FAST, REVERSE REACTION WHICH KICKS THE GUIDE BAR UP AND BACK TOWARD THE OPERATOR, IF THE SAW CHAIN IS PINCHED ALONG THE TOP OF THE GUIDE BAR, THE GUIDE BAR CAN BE DRIVEN RAPIDLY BACK TOWARD THE OPERATOR. EITHER OFTHESE RE.ACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. AVOID REACTIVE PINCH FORCES Pinch*Kickback and Pull-in occur when the chain is sud- denly stopped by being pinched, caught, or by contacting a foreign object in the wood. This sudden stopping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite direction of the chain rotation. Pinch-Kickback drives the saw straight back toward the operator: Pull-In pulls the saw away from the operator. Either reaction can result in loss of control and possibly serious injury, TO AVOID PINCH-KICKBACK: ⢠Be extremely aware of situations or obstructions that can cause material to pinch the top of or otherwise stop the chain. ⢠Do not cut more than one log at a time. ⢠Do not twist the saw as the bar is withdrawn from an under-cut when bucking. TO AVOID PULL-IN: ,, Always begin cuffing with the engine at full throttle and the saw housing against wood. ⢠Use wedges made,of plastic or wood, (never of metal) to hold the cut o_pen. . .::_'i - 12 -
OPERATION :23_ / TREE FELLING WARNING: IF THE TRUNK OR LIMBS ARE ROTTING, THEY CAN FALL UNEXPECTEDLY AND CAUSE SERIOUS INJURY, AS YOU MAKE YOUR FELLING CUT, IF THE SAW APPEARS TO BE BINDING, THE TREE IS STARTING TO FALL IN THE WRONG DIRECTION, IMMEDIATELY STOP THE SAW AND USE A FELLING WEDGE AND MAUL oHAMMER) TO FORCE THE FELLING CUT PEN. THE WEDGE WILL HOLD THE FELLING CUT OPEN ALLOWING YOU TO REMOVETHE SAW. KEEP EVERYONE AWAY FROM THE TREE IN ALL DIRECTIONS. DETERMINE THE NATURAL FALL DIRECTION ⢠Wind - A tree evenly balanced will fall in the same direc- tion the wind is btowing. ⢠Lean - Use a carpenter's level or plumb bob to deter- mine if tree has a natural lean. A leaning tree will tend to fall in direction of lean. ⢠Shape - A tree will tend to fail towards side that is more heavily branched. ⢠Other Factors - Contacting or nearby trees, buildings, or wires can influence the direction the tree wilt fall. CUTTING PROCEDURE (Fig. 12) After determining the Natural Fall Direction, the tree should be cut as follows: IMPORTANT: BEFORE FELLING A TREE, MAKE SURE YOU HAVE AT LEAST 3 FELLING WEDGES AND A MAUL (HAMMER) AVAILABLE FOR USE IF NEEDED. ⢠Use some means to visually mark the Natural Fall Direction. * Mark your notch cut on the Natural Fall Direction side of the tree approximately 18-24 inches above the ground. ⢠Cut top of the notch first at a 45 degree angle. Saw through 1/3 of the width of the tree. ⢠Cut bottom of the notch at a 45 degree angle until you meet the top notch cut. Remove notch of wood. ⢠On the side of the tree opposite the notch cut, make the felling cut. The felling cut should be 2 inches above the center point of the notch cut. Before the felting cut is complete, use wedges to open the cut when necessary to control the direction of the fall. Use wood or plastic wedges, but never steel or iron, to avoid kickback and chain damage. ⢠Cracking sounds, widening of the felling cut, movement in the upper branches are all signs that the tree is ready to fall. ⢠As tree begins to fall, turn off saw, and move quickly away from direction of fall Felling._ Direction _2" 1 S_I_ Top i g Notch _ cut Bottom Notch Cut /3 _ Buttress \ °oo, Figure 12 If your chain saw binds in the felling cut, you have three options: ⢠If the wrong direction of fall is acceptable, carefully remove the felling wedge. C_ deeper in the notch side of the tree until tree starts to fall. ⢠If the wrong direction of fall is not acceptable, attempt to use one or more felling wedges to force the tree in the original direction of fall. Do so by driving the wedges deeper into the felling cut. ⢠Keep everyone away from the tree in all directions and ⢠then seek professional help! FELLING TIPS ⢠Clear the work area of debris where you can have secure footing. ⢠Make sure there is enough room for the tree to fall. Maintain a distance of 2 1/2 tree lengths from the near- est person or other objects. Engine noise can drown out a warning call. ⢠Remove dirt, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made. ⢠Plan to stand on the up-hill side when cutting on a slope. ⢠Plan a clear retreat path to the rear and diagonal to the line of fall. ⢠Large buttress roots should be removed prior to notch CUt. " Use a wedge if there is any chance that the tree will not fall in the desired direction. ⢠We recommend you cut branches below shoulder height before felling tree. (See Limbing and Pruning). Be alert to signs that the tree is ready to fall: ⢠Cracking sounds. ⢠Widening of the felling cut. ° Movement in the upper branches.
OPERATION SAFETY FELLING SAFETY DON'T PUT YOURSELF IN THESE P OSITIONS Check the wind - Don't cut down wind Check the lean - Don't cut on down side Check the balance - Don't cut on weighted side I_IL WARNING: DO NOT CUT." - NEAR ELECTRICAL WIRES OR BUILDINGS. - IF YOU DO NOT KNOW TH E DIRECTION OF TREE FALL. - AT NIGHT. - DURING BAD WEATHER - RAIN, SNOW, STRONG WIND, ETC. ⢠Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator, ⢠Check for broken or dead branches which can fall on you while cutting. ⢠Be extremely cautious with partially fallen trees that may be poorly supported. When a tree doesn't fall completely, set the saw aside and pull down the tree w_th a cable winch, block and tackle, or tractor.To avoid injury, do not cut down a Dartially fallen tree with your saw. .... i â¢-_:- .: _::J,J -14-

NOTE -There are three adjustments on the carburetor. ⢠The Idle Speed Adjustment is marked with the letter "T." ⢠The two remaining adjustments on the carburetor are the mixture adjustments. One is marked "L" for low speed, and the other "H" for high speed. CARBURETOR PRESETS (Fig. 49) If your engine wilt not start due to suspected improper car- buretor adjustment, the following presets may be required. If used, it is recommended that all steps within the adjust- ment procedure be completed in order to assure a properly set carburetor. If presets are not needed, proceed to sec- tion "Idle Speed Adjustment." When making adjustments, be careful not to force the plas- tic limiter caps beyond the stops or damage will occur. Very small adjustments can affect engine performance. It is important to make slight adjustments and test performance before proceeding. Each adjustment°should be no more than 1/16 of a turn. â¢Tum both of the mixture adjustments clockwise until they stop, Do not overtighten as damage to the needles will occur ⢠Turn both mixture adjustments counterclockwise one full turn ⢠Turn the idle speed adjustment clockwise until it stops Now turn countemlockwise 4-1/2 turns ⢠If engine fails to start after performing carburetor presets, the unit may be ftooded. Review the "Difficult Starting" section of the manual. If problems continue, call the 1-800 number listed on the front cover of this manual for further assistance. ° Start the engine and operate for three (3) minutes to warm up. Go to =Adjusting Procedure." Idle Speed Adjustment Figure 49 Mixture Adjustment r::_ " 25 "
-.; SERVICE AND ADJUSTMENTS :iz-.! ADJUSTING PROCEDURE IDLE SPEED ADJUSTMENT "T" ⢠Allow the warm engine to idle. ⢠Adjust the Idte Speed until the engine continues to run without stalling and without the chain moving, - Turn clockwise to increase engine speed ff engine stalls or dies. - Turn countemlockwise to slow engine down and!or to keep the chain from turning. ⢠No further adjustments are necessary if chain does not move at idle speed and ff performance is satisfactory. LOW SPEED MIXTURE ADJUSTMENT "L" ⢠Allow engine to idle. ⢠Turn the Low Speed Mixture Adjustment slowly clock- wise until the RPM starts to drop. Note the position. ⢠Turn the Low Speed Mixture Adjustment slowly counter- clockwise until the RPM speeds up and starts to drop again, Note the position. ° Set the Low Speed Mixture at the midpoint between the two positions. HIGH SPEED MIXTURE ADJUSTMENT "H" IMPORTANT: DO NOT OPERATE ENGINE AT FULL THRO]-TLE FOR PROLONGED PERIODS WHILE MAK- ING HIGH SPEED ADJUSTMENTS AS DAMAGE TO THE ENGINE CAN OCCUR. ° Make a test cut. ⢠Based on performance of the saw while cutting, adjust the high speed mixture in 1/16 turn increments as fol- lows: - ClOse ff saw loses power in the cut. Do not adjust for best power by sound or speed, but #Jdge by how well the saw performs in the cut. - Counterclockwise if the saw has speed while out of the cut, but dies in the cut or lacks power while cutting. ° Repeat the test cut. ⢠Continue with 1/16 turn adjustments until the saw perfor- mance is acceptable while cutting. ⢠After completing adjustments, check for acceleration. ACCELERATION CHECK ⢠If the engine dies or hesitates instead of accelerating, turn the Low Speed Mixture Adjustment 1/16 of a turn at a time counterclockwise until you have smooth accelera- tion. ° Check the idle speed for stability and no chain move- ment. Adjust as necessary. ⢠Recheck for smooth acceleration and stable idle. Repeat process as necessary for acceptable performance. "_':zt2
STORAGE - ._.j Immediately prepare your unit for storage at the end of the season or ff it will not be used for 30 days or more, WARNING: ALLOW THE ENGINE TO COOL, AND SECURE THE UNIT BEFORE STORING OR TRANSPORTING IN A VEHICLE. STORE UNIT AND FUEL IN AN AREA WHERE FUEL VAPORS CANNOT REACH SPARKS OR OPEN FLAMES FROM WATER HEATERS, ELECTRIC MOTORS OR SWITCH -I STORE UNIT WITH ALL GUARDS IN PLACE. POSITION SO THAT ANY SHARP OBJECT CANNOT ACCIDENTALLY CAUSE INJURY TO PASSERS BY. STORE THE UNIT OUT OF THE REACH OF CHILDREN. GAS CHAIN SAW STORAGE INSTRUCTIONS if your chain is to be stored for a period of time, clean it thoroughly pdor to storage. Remove any dirt, sawdust, leaves, oi!, grease, etc. Store in a clean dry area. ⢠Clean the entire unit. ⢠Clean air filter. Refer to =Customer Responsibilities." ⢠Inspect the bar clamp area and clean any dirt, sawdust, grass, or debris that has collected. Inspect the guide bar and chain; replace a guide bar that is bent, warped, cracked, broken, or damaged in any other way. Replace a damaged or worn chain. ⢠Lightly oil external metal surfaces to prevent rust from forming. _h CAUTION: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. ⢠Apply a coating of oil to the entire surface of the guide bar and chain; wrap it in heavy paper or cloth. ⢠Be sure all handles and guards are in place and are securely fastened. Replace any damaged parts. FUEL SYSTEM Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur to fuel system com- ponents. Follow these instructions: ° Drain the fuel from the unit into an approved fuet con- tainer. ⢠Drain the fuel lines and carburetor by starting the engine and letting it run until it stops. ⢠Allow the engine to cool before storage. IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as the carbure- tor, fuel filter, fuel hose or tank during storage. Also, expe- dence indicates that alcohol blended fuels, those that use ethanol or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic gas which will damage your engine. To avoid engine problems, the fuet system should be emptied before storage of 30 days or longer. Fue! stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add sta- bilizer to the gasoline in the fuel tank or fuel storage con- tainer. Always follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding sta- bilizer to allow the stabilizer to reach the carburetor. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank. INTERNAL ENGINE ⢠Remove spark plug and pour t teaspoon of 40:1 2-cycle engine oil (AIR-COOLED) through the spark ptug open- ing. Slowly pull the starter rope 8 to 10 times to distribute oil to inner engine surfaces. ⢠Replace spark plug with a new one of the recommended type and heat range. Refer to "Product Specifications." ⢠Clean air filter. Refer to =Customer Responsibilities." ⢠Re-install all covers and hardware removed for access; tighten all screws and fasteners. ⢠Check entire unit for loose screws, nuts, and bolts- Replace any damaged, broken, or worn pads. ⢠Lightly oil external metal surface to prevent rust from forming. ⢠Use fresh fuel having the proper gasoline to oil ratio at the beginning of the next season. OTHER ⢠Do not store gasoline from one season to another. ⢠Replace your gasoline can if your can starts to rust. Rust and/or dirt in your fuelsystem will cause problems. ⢠Store your unit i_a well ventilated area and covered, if possible, to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will induce condensation and eventual rust or corrosion. IMPORTANT: NEVER COVER UNIT WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM. â¢c -27-

BECOME ALERT!!! YOUR SAFETY IS INVOLVED
,-. SAFETY RULES OPERATE YOUR SAW SAFELY ⢠Do not operate a chain saw with one hand. Serious injury to the operator, helpers, bystanders or any combina- tion of these persons may result from one-handed opera- tion. A chain saw is intended for two-handed use. ⢠Operate the chain saw only in well-ventilated outdoor areas. ⢠Do not operate saw from a ladder or in a tree, unless specifically trained to do so. ⢠Position all parts of your body to the left of cut and away from the chain when the engine is running. ⢠Cut wood only. Do not use your saw to pry or shove away limbs, roots, or other objects. ⢠Make sure the chain will not make contact with any object while starting the engine, Never try to start the saw when the guide bar is in a cut or kerr. ⢠Use extreme caution when cutting small size brush and saplings. Slender material can catch the chain and be whipped toward you or pull you off balance. ⢠Be alert for springback when cutting a limb that is under tension so you will not be struck by the limb or saw when the tension in the wood fibers is released. ⢠Do not put pressure on the saw at the end of a cut. Applying pressure can cause you to lose control when the cut is completed. ⢠Stop.the engine before setting the saw down. ⢠Keep fuel and oil caps, screws, and fasteners securely tightened. MAINTAIN YOUR SAW IN GOOD WORKING ORDER ⢠Have all chain saw service performed by your Sears Service Center with the exception of the items listed in the "Customer Responsibilities" section of this manual. For example, if improper tools are used to remove or ho{d the flywheel when servicing the clutch, structural damage to the flywheel can occur and cause the-flywheel to burst. ⢠Make certain the chain stops moving when the throttle trigger is released, For correction, refer to 'Carburetor Adjustments." ⢠Stop the saw if the chain strikes a foreign object. Inspect unit and repair or replace parts as necessary. ⢠Disconnect the spark plug before performing any maintenance except for carburetor adjustments. ⢠Never modify your saw in any way. Use only SEARS ' accessories and replacement parts as recommended. TRANSPORTING AND STORAGE ⢠Stop the unit before transporting. ⢠Allow engine to cool, cover the guide bar and chain, and secure the unit before storing or transporting in a vehicle. ⢠Empty fuel tank before storing or transporting the unit. Use up any fuel left in the carburetor by starting the engine and letting the engine run until it stops. ⢠Store unit and fuel in an area where fue! vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. ⢠Store unit so the chain cannot accidentally cause injury. ⢠Store the unit out of the r_ach of children. GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury. KICKBACK WARNING: KICKBACK CAN OCCUR WHEN THE MOV- ING CHAIN CONTACTS AN OBJECT ATTHE UPPER PORTION OFTHETIP OFTHE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE CHAIN IN THE CUT. CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR 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. IF THE CHAIN IS PINCHED ALONG THE TOP OF THE GUIDE BAR, THE GUIDE BAR CAN BE DRIVEN RAPIDLY BACK TOWARD THE OPERATOR. EITHER OFTHESE REACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. DO NOT RELY ONLY ON THE SAFETY DEVICES PROVIDED WITH YOUR SAW.

With a basic understanding of kicl_ack, you can reduce the element of surprise which contributes to accidents. * Never let the moving chain contact any object at the tip of the guide bar. Figure 2. . Keep the working area free from obstructions such as other trees, branches, rocks, fences, stumps, etc. Figure 3. Eliminate or avoid any obstruction that your chain could hit while you are cutting through a particular log or branch. , Keep your chain sharp and properly tenaioned.A loose or dull chain can increase the chance of kickback to occur. Follow manufacturer's chain sharpening and maintenance instructions. Check tension at regular intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after tensioning the chain. ⢠Begin and continue cutting at full throttle. If the chain is moving at a slower speed, there is greater chance for kick- back to occur. ⢠Cut one log at a time. ⢠Use extreme caution when re-entering a previous cut. ⢠Do not attempt plunge cuts. ⢠Watch for shifting logs or other forces that could close a cut and pinch or fall into chain. ° Use the Reduced-Kickback Guide Bar and Low- Kickback Chain specked for your saw. KICKBACK SAFETY FEATURES _ WARNING: THE FOLLOWING FEATURES ARE INCLUDED ON YOUR SAW TO HELP REDUCE THE HAZ- ARD OF KICKBACK; HOWEVER, SUCH FEA- TURES WILL NOT TOTALLY ELIMINATE THIS DANGEROUS REACTION. AS A CHAIN SAW USER, DO NOT RELY ONLY ON SAFETY DEVICES. YOU MUST FOLLOW ALL SAFETY PRECAUTIONS, INSTRUCTIONS, AND MAIN- TENANCE IN THIS MANUAL TO HELP AVOID KICKBACK AND OTHER FORCESWHICH CAN RESULT IN SERIOUS INJURY. Reduced-Kickback Guide Bar, designed with a sma radius tip,which reduces the size of the kickback danger zone on me guioe par tip. Figure 5, A Reduced-Kickback Guide Bar is one which has been demonstrated to signif- icantly reduce the number and seriousness of kickbacks MAINTAIN CONTROL ⢠Keep a good, firm grip on the saw with both hands when the engine is running and don't let go. Figure 4. A firm grip can neutralize kickback and help you maintain control of the saw. Keep the fingers of your left hand encir- cling and your left thumb under the front handlebar. Keep your right hand completely around the rear handle whether you are right handed or left handed. Keep your left arm straight with the elbow locked, ⢠Position your left hand on the front handlebar so it is in a sl_aight line with your right hand on the rear harp die when making bucking cuts. Figure 4. Never reverse right and left hand positions for any type of cutting. ⢠Stand with your weight evenly balanced on both feel ⢠Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting chain. Figure 4. ⢠Do not overreach. You could be drawn or thrown off bal- ance and lose control of the saw. ⢠Do not cut above shoulder heighL It is difficult to main- tain control of saw above shoulder height. UNDERSTANDING REACTWE FORCES Pinch-Kickback and Puff-In occur when the chain is sud- denly stopped by being pinched, caught, or by contact- ing a foreign object in the wood.This stopping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite direction of the chain rotation. Either reaction can result in loss of control and pos- sible serious injury. ⢠Pinch-Kickback -occurs when chain on top of guide bar is suddenly stopped. - rapidly d/_ves saw straight back toward operator. ⢠PulHn - occurs when the chain on the bottom of the guide bar is suddenly stopped. - pulis the saw rapidly forward. inch displacement specified in ANSI B175.1-1991.

OPERATION . JP £:=?_ BEFORE STARTING ENGINE WARNING: BE SURE TO READ THE FUEL HANDLING INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF THIS MANUAL BEFORE YOU BEGIN. IF YOU DO NOT UNDERSTAND THE FUEL HANDLING SECTION DO NOT ATTEMPT TO FUEL YOUR UNIT; SEEK HELP FROM SOMEONETHAT DOES UNDERSTAND THE FUEL HANDLING SECTION OR CALL THE CUSTOMER ASSISTANCE HOTLINE AT 1-800-235-5878, GUIDE BAR AND CHAIN OIL For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. if Craftsman bar oil is not available, you may use a good grade SAE30 oil until you are able to obtain Craftsman brand, The oi! output is automati- cally metered during operation. Your saw will use approxi- mately one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank. GASOLINE The two-cycle engine on this product requires a fuel mixture of regular unleeded gasoline and a quality 40:1 2-cycle engine oi! (AIR-COOLED) for lubrication of the bear- ings and other moving parts. The correct fuel/oil mixture is 40:1 (see Fuel Mixture Chart).Too little oil orthe incorrect oil type will cause poor performance and may cause the engine to overheat and seize. Gasoline and oll must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. This engine is certified to operate on unleaded gasoline. IMPORTANT: Experience indicates that alcohol blended fuels called gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas separation and for- marion of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer, Drain the gas tank, then run the fuel out of the carburetor and fuel lines by starting the engine and letting it run until it stops. Use fresh fuel next season. See STORAGE instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. FUEL STABILIZER Fuel stabilizer is an acceptable a.ltemative in minimizing the formation of fuel gum deposits during storage. Add stabiliz- er to gasoline in fuel tank or storage container. Always fol- tow the fuel mix ratio found on the stabilizer container. Run engine at teast 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. You do not have to drain the fuel tank for storage if you are using fuel stabilizer. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended w_ fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank. 40:1 2-CYCLE AIR-COOLED ENGINE OIL CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED)is strongly recommended. This oil is specifically blended with fuel stabilizers for increased fuel stability (extends fuel I_fe up to 5 times longer) and reduced smoke. If CRAFTSMAN 40:1 2-cycleengi_ne oil (AIR-COOLED).is not avellabie, use a good quality 2-cycle engine oil (AIR- COOLED) that has a recommended fuel mix ratio of 40:1. IMPORTANT! Do not use: ⢠AUTOMOTIVE OIL ⢠BOAT OILS (NMMA, BIA, etc.) These oils do not have proper additives for 2-cycle (AIR-COOLED) engines and can cause engine damage. GASOLINE AND OIL MIXTURE ⢠MIX GASOLINE AND OIL AS FOLLOWS: ⢠Consult chart for correct quantities. ⢠Do not mix gasoline and oil directly in the unit's fuel tank, FOR ONE GALLON: ⢠Pour 3,2 ounces of high quality, 40:1 2-cycle engine oil (AIR-COOLED) into an empty, approved one gallon gasoline container. ⢠Add one gallon of regular unleaded gasoline to the gallon container, then securely replace the cap. ⢠Shake the corttainet'momentadly. ⢠The mixture is now ready for use. Fuel stabilizer can be added at this time if desired; follow mixing instructions on the label FUEL MIXTURE CHART 40:1 Fuel:Oil Mix Ratio I _ Oil (fLoz.I 1 gallon 3.2 2.5 gallons 8.0 NOTE: Fuel containers may hold more than the specified amount. If too much gasoline is in the container, the result- ing gas-to-oil fuel mixture will not be correct for proper engine operation. -10-

⢠7 :i .... = OPERATION ,.,,, ,, ............ ii GENERAL OPERATION TIPS ⢠cut wood only. Do not cut metal; plastics; masonry; non- wood building materials; etc. ⢠Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or replace parts as necessary. ⢠Keep the chain out of dirt and sand. Even a sma!l amount of dirt will quickly dull a chain and thus increase the pos- sibility of kickback. To get the =feel" of using your saw before you begin a major sawing operation, practice cutting a few small Jogs using the following technique: ⢠Accelerate engine to full throttle by squeezing the throttle trigger before entering cut. ⢠Never cut with engine at partial speeds. ⢠Begin cutting with the saw chassis against the log. ⢠Keep engine at full throttle during cutting procedure. ⢠Allow the chain to cut for you; exert only light downward pressure. If you force the cut, damage to the bar, chain, or engine can result. ⢠Release the throttle trigger as soon as the cut is com- pleted, allowing the engine to idle. If you run the unit at full throttle without cutting, unnecessary wear can occur to the chain, bar, and engine. ⢠To avoid losing control when completing the cut, do not put pressure on the saw during the end of the cut. ⢠Stop engine before setting unit down after operation. OPERATION SAFETY ,,i,,.Hi m Hi L i,H Hi = WARNING: IF SAW BECOMES PINCHED OR HUNG IN A LOG, DO Nor TRY TO FORCE IT OUT. YOU CAN LOSE CONTROL OF THE SAW RESULTING IN INJURY AND/OR DAMAGE TO THE SAW. STOP THE SAW, DRIVE A WEDGE OF PLASTIC OR WOOD INTO THE CUT UNTIL THE SAW CAN BE REMOVED EASILY. RESTARTTHE SAW AND CAREFUL- LY REENTER THE CUT. TO AVOID KICK- BACK AND CHAIN DAMAGE, DO NOT USE A METAL WEDGE. DO NOT ATTEMPT TO RESTART YOUR SAW WHEN IT IS PINCHED OR HUNG IN A LOG. KICKBACK CAN OCCUR WHEN THE MOV- ING CHAIN CONTACTS AN OBJECT AT THE UPPER PORTION OFTHETIP OFTHE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE SAW CHAIN IN THE CUT. CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR CAN CAUSE THE CHAINTO DIG INTOTHE OBJECT AND STOP THE CHAIN FOR AN INSTANT.THE RESULT IS A LIGHTNING FAST, REVERSE REACTION WHICH KICKS THE GUIDE BAR UP AND BACK TOWARD THE OPERATOR, IF THE SAW CHAIN IS PINCHED ALONG THE TOP OF THE GUIDE BAR, THE GUIDE BAR CAN BE DRIVEN RAPIDLY BACK TOWARD THE OPERATOR. EITHER OFTHESE RE.ACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. AVOID REACTIVE PINCH FORCES Pinch*Kickback and Pull-in occur when the chain is sud- denly stopped by being pinched, caught, or by contacting a foreign object in the wood. This sudden stopping of the chain results in a reversal of the chain force used to cut wood and causes the saw to move in the opposite direction of the chain rotation. Pinch-Kickback drives the saw straight back toward the operator: Pull-In pulls the saw away from the operator. Either reaction can result in loss of control and possibly serious injury, TO AVOID PINCH-KICKBACK: ⢠Be extremely aware of situations or obstructions that can cause material to pinch the top of or otherwise stop the chain. ⢠Do not cut more than one log at a time. ⢠Do not twist the saw as the bar is withdrawn from an under-cut when bucking. TO AVOID PULL-IN: ,, Always begin cuffing with the engine at full throttle and the saw housing against wood. ⢠Use wedges made,of plastic or wood, (never of metal) to hold the cut o_pen. . .::_'i - 12 -
OPERATION :23_ / TREE FELLING WARNING: IF THE TRUNK OR LIMBS ARE ROTTING, THEY CAN FALL UNEXPECTEDLY AND CAUSE SERIOUS INJURY, AS YOU MAKE YOUR FELLING CUT, IF THE SAW APPEARS TO BE BINDING, THE TREE IS STARTING TO FALL IN THE WRONG DIRECTION, IMMEDIATELY STOP THE SAW AND USE A FELLING WEDGE AND MAUL oHAMMER) TO FORCE THE FELLING CUT PEN. THE WEDGE WILL HOLD THE FELLING CUT OPEN ALLOWING YOU TO REMOVETHE SAW. KEEP EVERYONE AWAY FROM THE TREE IN ALL DIRECTIONS. DETERMINE THE NATURAL FALL DIRECTION ⢠Wind - A tree evenly balanced will fall in the same direc- tion the wind is btowing. ⢠Lean - Use a carpenter's level or plumb bob to deter- mine if tree has a natural lean. A leaning tree will tend to fall in direction of lean. ⢠Shape - A tree will tend to fail towards side that is more heavily branched. ⢠Other Factors - Contacting or nearby trees, buildings, or wires can influence the direction the tree wilt fall. CUTTING PROCEDURE (Fig. 12) After determining the Natural Fall Direction, the tree should be cut as follows: IMPORTANT: BEFORE FELLING A TREE, MAKE SURE YOU HAVE AT LEAST 3 FELLING WEDGES AND A MAUL (HAMMER) AVAILABLE FOR USE IF NEEDED. ⢠Use some means to visually mark the Natural Fall Direction. * Mark your notch cut on the Natural Fall Direction side of the tree approximately 18-24 inches above the ground. ⢠Cut top of the notch first at a 45 degree angle. Saw through 1/3 of the width of the tree. ⢠Cut bottom of the notch at a 45 degree angle until you meet the top notch cut. Remove notch of wood. ⢠On the side of the tree opposite the notch cut, make the felling cut. The felling cut should be 2 inches above the center point of the notch cut. Before the felting cut is complete, use wedges to open the cut when necessary to control the direction of the fall. Use wood or plastic wedges, but never steel or iron, to avoid kickback and chain damage. ⢠Cracking sounds, widening of the felling cut, movement in the upper branches are all signs that the tree is ready to fall. ⢠As tree begins to fall, turn off saw, and move quickly away from direction of fall Felling._ Direction _2" 1 S_I_ Top i g Notch _ cut Bottom Notch Cut /3 _ Buttress \ °oo, Figure 12 If your chain saw binds in the felling cut, you have three options: ⢠If the wrong direction of fall is acceptable, carefully remove the felling wedge. C_ deeper in the notch side of the tree until tree starts to fall. ⢠If the wrong direction of fall is not acceptable, attempt to use one or more felling wedges to force the tree in the original direction of fall. Do so by driving the wedges deeper into the felling cut. ⢠Keep everyone away from the tree in all directions and ⢠then seek professional help! FELLING TIPS ⢠Clear the work area of debris where you can have secure footing. ⢠Make sure there is enough room for the tree to fall. Maintain a distance of 2 1/2 tree lengths from the near- est person or other objects. Engine noise can drown out a warning call. ⢠Remove dirt, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made. ⢠Plan to stand on the up-hill side when cutting on a slope. ⢠Plan a clear retreat path to the rear and diagonal to the line of fall. ⢠Large buttress roots should be removed prior to notch CUt. " Use a wedge if there is any chance that the tree will not fall in the desired direction. ⢠We recommend you cut branches below shoulder height before felling tree. (See Limbing and Pruning). Be alert to signs that the tree is ready to fall: ⢠Cracking sounds. ⢠Widening of the felling cut. ° Movement in the upper branches.
OPERATION SAFETY FELLING SAFETY DON'T PUT YOURSELF IN THESE P OSITIONS Check the wind - Don't cut down wind Check the lean - Don't cut on down side Check the balance - Don't cut on weighted side I_IL WARNING: DO NOT CUT." - NEAR ELECTRICAL WIRES OR BUILDINGS. - IF YOU DO NOT KNOW TH E DIRECTION OF TREE FALL. - AT NIGHT. - DURING BAD WEATHER - RAIN, SNOW, STRONG WIND, ETC. ⢠Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator, ⢠Check for broken or dead branches which can fall on you while cutting. ⢠Be extremely cautious with partially fallen trees that may be poorly supported. When a tree doesn't fall completely, set the saw aside and pull down the tree w_th a cable winch, block and tackle, or tractor.To avoid injury, do not cut down a Dartially fallen tree with your saw. .... i â¢-_:- .: _::J,J -14-
OPERATION ":. :G?] ,i "2- i_ BUCKING Bucking is cutting a fallen tree to the desired log size. TYPES OF CUTTING (Fig. 13) ⢠Overcutting - begin on the top side of the log with the bottom of the saw chassis against the log; exert light pressure downward. ⢠Undercutting -begin on the underside of the tog with the top of the saw chassis against the log; exert light pres- sure upward. During undercutting, the saw will tend to push back at you, Be prepared for this reaction and hold the saw firmly to maintain control, Saw Chassis BUCKING USING A SUPPORT (Fig. 15 & 16) Another log or a stand, such as a sawhorse, may be used as supports when bucking. ⢠Area A - Undemut 1/3 of the way through the log. - Finish with an ovetcut, ⢠Area B - Overcut 1/3 of the way through the log. - Finish with an undercut.

Sharp pieces of wood could be flung toward the operator. ⢠Use a sawhorse to cut small logs. Never allow another person to hold the log while cutting and never hold the log with your leg or foot. ⢠Do not cut in an area where logs, limbs, and roots are tangled such as ira bl6wn down area. Drag the logs into a clear area before cutting by pulling out exposed and cleared logs first. ' ⢠Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log. OPERATION SAFETY BUCKING SAFETY WARNING: DO NOT STAND ON THE LOG BEING CUT, ANY PORTION CAN ROLL CAUSING LOSS OF FOOTING AND CONTROL, NEVER TURN THE SAW UPSIDE DOWN TO UNDERCUT.

LIMBING (Fig. 17) ⢠Start at base of the felled tree and work toward the top. ⢠Leave the larger limbs underneath the felled tree to support the tree as you work. Figure 17 PRUNING (Fig. 18) Small branches - smaller than width of guide bar. Large branches - larger than width of guide bar. ⢠Remove small limbs with one cut. ⢠Remove larger, supporting branches with the 1/3 - 2/3 cutting techniques described in the bucking section. PRUNING PROCEDURE ⢠Cut 1 - Undercut 1/3 of the way through the limb near the trunk of the tree. ⢠Cut 2 - Finish with an overcut farther out from the trunk until the limb falls. Keep out of the way of the fairing limb. ⢠Pruning Cut - Cut the limb stump flush at the edge of l Cut 2 Pruning Cut Cut 1 ⢠' , Figure18 J PRUNING AND LIMBING TIPS ⢠Work slowly, keeping both hands firmly gripped on the saw. Maintain secure footing and balance. ⢠Keep a clear work area.Frequently clear branches out of the way to avoid tripping over them. ⢠Leave the larger limbs underneath the felled tree to sup- port the tree as you work. ⢠Start at the base of the felled tree and work toward the top. ° Keep the tree between you and the chain. Cut from the side of the tree opposite the branch you are cutting. ⢠Limit pruning to limbs shoulder height or below. " ⢠Keep out of the way of the falling limb.

SERVICE AND ADJUSTMENTS _t CARBURETOR ADJUSTMENTS Carburetor adjustment is critical and if done improper- ly can permanently damage the engine as well as the carburetor. Please read all instructions and consult the Trouble Shooting section of this manual before begin- ning this process. If the engine does not operate according to these instructions after repeating the adjusting steps, do not use the uniL For further assis- tance, please call our customer assistance hotline at 1-800-235-5878. WARNING': THE CHAIN WILL BE MOVING DURING MOST OF THIS PROCEDURE. WEAR YOUR PROTECTIVE EQUIPMENT AND OBSERVE ALL SAFETY PRECAUTIONS. IN "LOW SPEED MIXTURE ADJUflTME_" RECHECK IDLE SPEED AFTER EACH ADJUSTMENT. THE CHAIN MUST NOT MOVE AT IDLE SPEED. If engine does not start, it may be flooded, if in doubt, read the section on fleoded engine in the starting section of this manual prior to beginning any adjustments. The carburetor has been adjusted at the factory for sea level conditions. Adjustments may become necessary if the saw is used at significantly higher altitudes or if you notice any of the following conditions: ⢠Chain moves when the engine runs at idle speed. See "ldte Speed Adjustment." ⢠Saw will not idle. See "Idle Speed Adjustment" and "Low Speed Mixture Adjustment." ⢠Engine dies or hesitates when it should accelerate. See "Aoceteration Adjustment." ⢠Loss of cutting power which is not corrected by air filter cleaning. See "High Speed Mixture Adjustment." NOTE -There are three adjustments on the carburetor. ⢠The Idle Speed Adjustment is marked with the letter "T." ⢠The two remaining adjustments on the carburetor are the mixture adjustments. One is marked "L" for low speed, and the other "H" for high speed. CARBURETOR PRESETS (Fig. 49) If your engine wilt not start due to suspected improper car- buretor adjustment, the following presets may be required. If used, it is recommended that all steps within the adjust- ment procedure be completed in order to assure a properly set carburetor. If presets are not needed, proceed to sec- tion "Idle Speed Adjustment." When making adjustments, be careful not to force the plas- tic limiter caps beyond the stops or damage will occur. Very small adjustments can affect engine performance. It is important to make slight adjustments and test performance before proceeding. Each adjustment°should be no more than 1/16 of a turn. â¢Tum both of the mixture adjustments clockwise until they stop, Do not overtighten as damage to the needles will occur ⢠Turn both mixture adjustments counterclockwise one full turn ⢠Turn the idle speed adjustment clockwise until it stops Now turn countemlockwise 4-1/2 turns ⢠If engine fails to start after performing carburetor presets, the unit may be ftooded.

LOW SPEED MIXTURE ADJUSTMENT "L" ⢠Allow engine to idle. ⢠Turn the Low Speed Mixture Adjustment slowly clock- wise until the RPM starts to drop. Note the position. ⢠Turn the Low Speed Mixture Adjustment slowly counter- clockwise until the RPM speeds up and starts to drop again, Note the position. ° Set the Low Speed Mixture at the midpoint between the two positions. HIGH SPEED MIXTURE ADJUSTMENT "H" IMPORTANT: DO NOT OPERATE ENGINE AT FULL THRO]-TLE FOR PROLONGED PERIODS WHILE MAK- ING HIGH SPEED ADJUSTMENTS AS DAMAGE TO THE ENGINE CAN OCCUR. ° Make a test cut. ⢠Based on performance of the saw while cutting, adjust the high speed mixture in 1/16 turn increments as fol- lows: - ClOse ff saw loses power in the cut. Do not adjust for best power by sound or speed, but #Jdge by how well the saw performs in the cut. - Counterclockwise if the saw has speed while out of the cut, but dies in the cut or lacks power while cutting. ° Repeat the test cut. ⢠Continue with 1/16 turn adjustments until the saw perfor- mance is acceptable while cutting. ⢠After completing adjustments, check for acceleration. ACCELERATION CHECK ⢠If the engine dies or hesitates instead of accelerating, turn the Low Speed Mixture Adjustment 1/16 of a turn at a time counterclockwise until you have smooth accelera- tion. ° Check the idle speed for stability and no chain move- ment. Adjust as necessary. ⢠Recheck for smooth acceleration and stable idle. Repeat process as necessary for acceptable performance. "_':zt2
STORAGE - ._.j Immediately prepare your unit for storage at the end of the season or ff it will not be used for 30 days or more, WARNING: ALLOW THE ENGINE TO COOL, AND SECURE THE UNIT BEFORE STORING OR TRANSPORTING IN A VEHICLE. STORE UNIT AND FUEL IN AN AREA WHERE FUEL VAPORS CANNOT REACH SPARKS OR OPEN FLAMES FROM WATER HEATERS, ELECTRIC MOTORS OR SWITCH -I STORE UNIT WITH ALL GUARDS IN PLACE. POSITION SO THAT ANY SHARP OBJECT CANNOT ACCIDENTALLY CAUSE INJURY TO PASSERS BY. STORE THE UNIT OUT OF THE REACH OF CHILDREN. GAS CHAIN SAW STORAGE INSTRUCTIONS if your chain is to be stored for a period of time, clean it thoroughly pdor to storage. Remove any dirt, sawdust, leaves, oi!, grease, etc. Store in a clean dry area. ⢠Clean the entire unit. ⢠Clean air filter. Refer to =Customer Responsibilities." ⢠Inspect the bar clamp area and clean any dirt, sawdust, grass, or debris that has collected. Inspect the guide bar and chain; replace a guide bar that is bent, warped, cracked, broken, or damaged in any other way. Replace a damaged or worn chain. ⢠Lightly oil external metal surfaces to prevent rust from forming. _h CAUTION: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving. ⢠Apply a coating of oil to the entire surface of the guide bar and chain; wrap it in heavy paper or cloth. ⢠Be sure all handles and guards are in place and are securely fastened. Replace any damaged parts. FUEL SYSTEM Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur to fuel system com- ponents. Follow these instructions: ° Drain the fuel from the unit into an approved fuet con- tainer. ⢠Drain the fuel lines and carburetor by starting the engine and letting it run until it stops. ⢠Allow the engine to cool before storage. IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as the carbure- tor, fuel filter, fuel hose or tank during storage. Also, expe- dence indicates that alcohol blended fuels, those that use ethanol or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic gas which will damage your engine. To avoid engine problems, the fuet system should be emptied before storage of 30 days or longer. Fue! stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add sta- bilizer to the gasoline in the fuel tank or fuel storage con- tainer. Always follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding sta- bilizer to allow the stabilizer to reach the carburetor. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizer. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank. INTERNAL ENGINE ⢠Remove spark plug and pour t teaspoon of 40:1 2-cycle engine oil (AIR-COOLED) through the spark ptug open- ing. Slowly pull the starter rope 8 to 10 times to distribute oil to inner engine surfaces. ⢠Replace spark plug with a new one of the recommended type and heat range. Refer to "Product Specifications." ⢠Clean air filter. Refer to =Customer Responsibilities." ⢠Re-install all covers and hardware removed for access; tighten all screws and fasteners. ⢠Check entire unit for loose screws, nuts, and bolts- Replace any damaged, broken, or worn pads. ⢠Lightly oil external metal surface to prevent rust from forming. ⢠Use fresh fuel having the proper gasoline to oil ratio at the beginning of the next season. OTHER ⢠Do not store gasoline from one season to another. ⢠Replace your gasoline can if your can starts to rust. Rust and/or dirt in your fuelsystem will cause problems. ⢠Store your unit i_a well ventilated area and covered, if possible, to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will induce condensation and eventual rust or corrosion. IMPORTANT: NEVER COVER UNIT WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM. â¢c -27-
