Always use steel-toed safety footwear with non-slip soles; snug-fitting clothing; heavy-duty, non-slip gloves; eye protection such as non-fogging, vented goggles or face screen; an approved safety hard hat; and sound barriers (ear plugs or mufflers) to protect your hearing. Reg- ular users should have hearing checked regularly as chain saw noise can damage hearing. • Secure hair above shoulder length. Do not wear loose clothing or jewelry; they can get caught in moving parts. • Keep all parts of your body away from the chain when the engine is running. • Keep children, bystanders, and ani- mals a minimum of 30 feet (10 me- ters) away from the work area when starting and using the saw. • Do not handle or operate a chain saw when you are fatigued, ill, or up- set, or if you have taken alcohol, drugs, or medication. You must be in good physical condition and mentally alert. If you have any condition that might be aggravated by strenuous work, check with doctor before oper- ating. • Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned re- treat path. 2
OPERATE YOUR SAW SAFELY • Do not operate a chain saw with one hand. Serious injury to the operator, heipers, bystanders or any combina- tion of these persons may result from one-handed operation. A chain saw is intended for two-handed use. • Operate the chain saw only in a welt- ventilated outdoor area. • Do not operate saw from a ladder or in a tree. • 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. • Do not put pressure on the saw at the end of the cut. Applying pressure can cause you to _ose control when the cut is completed. • Stop engine before setting saw down. • Hand carry saw only when engine is stopped. Carry with muffler away from body; guide bar & chain project- ing behind you; guide bar preferably covered with a scabbard. • Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely as- sembled. Atways reptace bar, chain, hand guard, or chain brake immedi- ately if it becomes damaged, broken or is otherwise removed. MAINTAIN YOUR SAW IN GOOD WORKING ORDER ,I_ WARNING: Disconnect the spark plug before performing mainte- nance except carburetor adjustments. • Have nil chain saw service performed by a qualified service dealer with the exception of the items listed in the MAINTENANCE section of this manual. • Make certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETOR ADJUSTMENT • Keep the handies dry, clean, and free from oil or fuet mixture. • Keep caps and fasteners securely tightened. • Nonconforming replacement compo- nents or the removal of safety devices may cause damage to the unit and possible injury to the operator or by- standers. Use only Craftsman acces- sories and replacement parts as rec- ommended. Never modify your saw. • Maintain chain saw with care. • Keep unit sharp and clean for better and safer performance. • FoItow instructions for lubricating and changing accessories. • Check for damaged parts. Before fur- ther use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged shouM be properly repaired or replaced by a Sears Service Center unless otherwise indicated elsewhere in the operator's manual. • When not in use, chain saws should be stored in a dry, high or locked-up place out of the reach of children. • When storing saw, use a scabbard or carrying case. HANDLE FUEL WITH CAUTION • Do not smoke while handling fuel or while operating the saw. • Eliminate att sources of sparks or flame in the areas where fuel is mixed or poured. • Mix and pour fuel in an outdoor area and use an approved, marked con- tainer for all fuet purposes. Wipe up atl fuel splits before starting saw. • Move at least 10 feet (3 meters) from fueling site before starting engine. • Turn the engine off and let saw cooI in a non-combustible area, not on dry leaves, straw, paper, etc. Slowly remove fuet cap and refuel unit. • Empty the fuel tank before storing or transporting the unit. Use up fueI left in the carburetor by starting the engine and letting it run until it stops. • Store the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. GUARD AGAINST KICKBACK Follow alI safety ruIes to help avoid kickback and other forces which can result in serious injury. _,_\ _,_ Kickback Path Avoid Obstructions Clear The Working Area
_ILWARNING: Avoid kickback which can resuIt in serious injury. Kickback is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar contacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign object in the wood can also re- suit in loss of chain saw control • 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. • Pinch-Kickback can occur when the the wood ctoses in and pinches the moving saw chain in the cut along the top of the guide bar and the saw chain is suddenly stopped. This sud- den 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. The saw is driven straight back toward the operator. • Pull-In can occur when the moving chain contacts a foreign object in the wood in the cut along the bottom of the guide bar and the saw chain is suddenly stopped. This sudden stop- ping puils the saw forward and away from the operator and could easily cause the operator to lose control of the saw, REDUCE THE CHANCE OF KICKBACK • Recognize that kickback can hap- pen. With a basic understanding of kickback, you can reduce the ele- ment of surprise which contributes to accidents. • Never tet the moving chain contact any object at the tip of the guide bar. • Keep the working area free from ob- structions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain couId hit white you are cutting. • When cutting a branch, do not let the guide bar contact branch or other ob- jects around it. • Keep saw chain sharp and properly tensioned, A loose or dull chain can increase the chance of kickback, Fol- low manufacturer's chain sharpening and maintenance instructions. Check tension at regular intervals, but never with the engine running. Make sure the bar nuts are securely tightened. • Begin and continue cutting at futl speed. If the chain is moving at a slower speed, there is greater chance of kickback occurring. • Use extreme caution when re-enter- ing a previous cut, • Do not attempt cuts starting with the tip of the bar (plunge cuts), • Watch for shifting logs or other forces that could close a cut and pinch or fail into chain, • Use the Reduced-Kickback Guide Bar and Low-Kickback Chain speci- fied for your saw, 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 undercut when bucking. Avoid Putl-ln: • Always begin cutting with the engine at full speed and the saw housing against wood. • Use wedges made of ptastic or wood. Never use metal to ho_d the cut open. MAINTAIN CONTROL Stand to the left of the saw Thumb on h O,s,de ",{ Never reverse hand positions • A good, firm grip on the saw with both hands will heIp you maintain control. Don't let go. Grip the rear handle with your right hand whether you are right or left handed. Wrap the fingers of your left hand over and around the front handlebar, and your teft thumb under the front handlebar. Keep your ieff arm straight with the elbow locked,
• Position your left hand on the front handtebar so it is in a straight tine with your right hand on the rear handle when making bucking cuts. Never reverse right and left hand positions for any type of cutting. • Stand with your weight evenly bal- anced on both feet. • Do not overreach. You couid be drawn or thrown off balance and lose control of the saw. • Do not cut above shoulder height, tt is difficuIt to maintain control of saw above shoulder height. KICKBACK SAFETY FEATURES WARNING: The following fea- tures are included on your saw to help reduce the hazard of kickback; however, such features witl not totaity eliminate this danger. Do not rety only on safety devices. Foltow atl safety rules to hetp avoid kickback and other forces which can result in serious injury. • Front Hand Guard, designed to reduce the chance of your left hand contact- ing the chain if your hand slips off the front handlebar. • Position of front and rear handlebars, designed with distance between han- dles and "in-line" with each other. The spread and "in-line" position of the hands provided by this design work together to give balance and resis- tance in controlling the pivot of the saw back toward the operator if kick- back occurs. • Reduced-Kickback Guide Bar, de- signed with a smatl radius tip which reduces the size of the kickback danger zone on the bar tip. This type of bar has been demonstrated to sig- nificantly reduce the number and se- riousness of kickbacks when tested in accordance with ANSI B175.1. _& SmaII Radius Tip Guide Bar Large Radius _ "_ Tip Guide Bar • Low-Kickback Chain, has met kick- back performance requirements when tested on a representative sampie of chain saws below 3.8 cu- bic inch displacement specified in ANSi B175.1. Low-Kickback Chain Contoured Depth Gauge _._ longated Guard Link deflects kickback force And allows wood to gradually ride into Cutter CHAIN BRAKE • Chain Brake, designed to stop the chain in the event of kickback. _0&WARNING: WE DO NOT REP- RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICK- BACK Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kick- back can be caused by aIIowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE DEVICES BUILT iNTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced-kickback guide bars and Jow- kickback saw chains reduce the chance and magnitude of kickback and are rec- ommended. Your saw has a tow kick- back chain and bar as original equip- ment. Repairs on a chain brake should be made by an authorized Sears Ser- vice Center. Take your unit to the place of purchase if purchased from a servic- ing dealer, or to your nearest Sears Ser- vice Center • Tip contact in some cases may cause a Iightning fast reverse REACTION, kicking guide bar up and back toward 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 control of the saw which could result in serious injury. Do not rely exclusively upon devices built into your SaW.

BEFORE STARTING ENGINE _ll, WARNING: Muffter is very hot during and after use. Do not touch the muffIer or allow combustible material such as dry grass or fuel to do so. _LWARNING: Be sure to read the fuel handling information in the safety rules section of this manual before you begin, tf you do not understand the fuel handling information do not at- tempt to fuel your unit. Seek help from someone that does understand the in- formation or can the customer assis- tance help line at 1-800-235-5878. GUIDE BAR AND CHAIN OIL The bar and chain require lubrication. The chain oiler provides continuous Iubrication to the chain and guide bar. Be sure to fiIt the bar oil tank when you fill the fueI tank (Capacity = 6.8 ft. oz.). Lack of oil win quickly ruin the bar and chain. Too little oil will cause overheat- ing shown by smoke coming from the chain and/or discoloration of the bar. For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. If Craftsman bar oit is not available, you may use a good grade SAE 30 oiI until you are aMe to obtain Craftsman brand. The oil output is automatically metered during opera- tion. Your saw will use approximately one tank of bar oil for every tank of fuel mix. Atways fill the bar oil tank when you fill the fuet tank. FUELING ENGINE _WARNING: Remove fuel cap slowly when refueling. This engine is certified to operate on unteaded gasoline. Before operation, gasotine must be mixed with a good quatity synthetic 2-cycIe air-cooIed en- gine oil. We recommend Craftsman brand synthetic oil. Mix gasoline and oit at a ratio of 40:1. A 40:1 ratio is ob- tained by mixing 3.2 ounces of oil with 1 gailon of unleaded gasoline. Included with this saw is a 3.2 ounce container of oil Pour the entire contents of this con- tainer into 1 gallon of gasoline to achieve the proper fuel mixture. DO NOT USE automotive or boat oil These oils wiit cause engine damage. When mixing fuel fottow the instruc- tions printed on the oil container. Once oil is added to the gasoline, shake container momentarily to assure that the fuet is thoroughly mixed. Always read and follow the safety rules relat- ing to fueI before fueling your unit. IMPORTANT Experience indicates that alcohol- blended fueis (called gasohol or using ethanot or methanol) can attract mois- ture which leads to separation and formation 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, start the en- gine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or car- buretor cteaner products in the fuel tank or permanent damage may occur, See the STORAGE section for additionai information CHAIN BRAKE Ensure chain brake is disengaged by pulling the front hand guard back toward the front handle as far as possible. The chain brake must be disengaged before cutting with the saw. _ WARNING: The chain must not move when the engine runs at idle speed. If the chain moves at idle speed refer to CARBURETOR ADJUST- MENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns. STOPPING YOUR ENGINE • Release the throttle trigger. • Move ON/STOP switch to the STOP position. STARTING POSITION • To start the engine, hold the saw firmly on the ground as iitustrated. Make sure the chain is free to turn without contacting any object. Starter Rope Handle Left Hand on Front Handle Right Foot Through Rear Handle
_ILWARNING: Do not attempt to throw or drop-start the chain saw, Doing so witt put the operator at risk of serious injury due to loss of controI of the chain saw. IMPORTANT POINTS TO REMEMBER When puIIing the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. HoM the han- dle and let the rope rewind stowty. For cold weather starting, start the unit at FULL CHOKE; allow the engine to warm up before squeezing the throttle trigger. NOTE: Do not attempt to cut material with the choke/fast idle lever in the FULL CHOKE position.

DIFFICULT STARTING (or 8tatting a flooded engine) The engine may be flooded with too much fuet if it has not started after 10 pulls. Flooded engines can be cleared of ex- cess fuel by pushing the choke/fast idle lever in completeIy (to the OFF CHOKE position) and then following the warm engine starting procedure listed above. Ensure the ON/STOP switch is in the ON position, Starting could require pulling the start- er rope handle many times depending on how badly the unit is flooded, If en- gine fails to start, refer to the TROU- BLESHOOTING TABLE or call 1-800-235-5878.
CHAIN BRAKE _b'WARNING: If the brake band is worn too thin it may break when the chain brake is triggered. With a broken brake band, the chain brake will not stop the chain. The chain brake must be replaced if any part is worn to tess than 0.020" (0.5 ram) thick. Repairs on a chain brake should be made by your Sears Service Center. Take your unit to the piace of purchase or to the near- est Sears Service Center. • This saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs. • The inertia-activated chain brake is activated if the front hand guard is pushed forward, either manually (by hand) or automatically (by sudden movement). • If the brake is already activated, it is disengaged by puiting the front hand guard back toward the front handle as far as possible. • When cutting with the saw, the chain brake must be disengaged. Braking function control CAUTION: The chain brake must be checked several times daily. The en- gine must be running when performing this procedure. This is the onIy instance when the saw shouid be placed on the ground with the engine running. Place the saw on firm ground. Grip the rear handle with your right hand and the front handle with your left hand. Apply futt throttle by fully depressing the throttle trigger. Activate the chain brake by turning your left wrist against the hand guard without releasing your grip around the front handle. The chain shoutd stop immediately. Inertia activating function control _kWARNING: When performing the foitowing procedure, the engine must be turned off. Grip the rear handte with your right hand and the front handle with your teft hand. Hotd the chain saw approximately 14 inches (35 cm) above a stump or other wooden surface. Reiease your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate. OPERATING TIPS • Check chain tension before first use and after 1 minute of operation, and each time before you start the chain saw. See CHAIN TENSION in the MAINTENANCE section. • Cut wood only. Do not cut metaI, plas- tics, masonry, non-wood building ma- terials, etc. • Stop the saw if the chain strikes a foreign object. Inspect the saw and repair or replace parts as necessary. If the chain jumps off the guide bar, inspect the chain for damaged drive links before reinstalling. Burrs on drive links, which prevent them from entering the groove of the guide bar, can be removed with a flat rite. • Keep the chain out of dirt and sand. Even a smaII amount of dirt will dull a chain, increase the possibility of kick- back, and require chain sharpening or replacement. • Practice cutting a few small logs us- ing the following techniques to get the "feeF of using your saw before you begin a major sawing operation. • Squeeze the throttIe trigger and allow the engine to reach full speed before cutting. • Begin cutting with the saw frame against the log. • Keep the engine at full speed the entire time you are cutting. • Altow the chain to cut for you. Exert onty light downward pressure, tf you force the cut, damage to the bar, chain, or engine can result. • Release the throttle trigger as soon as the cut is completed, allowing the engine to idle. Ifyou run the saw at full throttle without a cutting toad, unnecessary wear can occur to the chain, bar, and engine. To maxi- mize operating efficiency, do not run the engine for longer than 30 _econd_ at a time at full throttle. • To avoid losing control when cut is complete, do not put pressure on saw at end of cut. • Stop the engine before setting the saw down after cutting. 10
TREE FELLING TECHNIQUES _II, WARNING: Check for broken or dead branches which can fall while cut- ting causing serious injury. Do not cut near buildings or electrical wires if you do not know the direction of tree falt, nor cut at night since you will not be aIe to see well, nor during bad weather such as rain, snow, or strong winds, etc. tf the tree makes contact with any utility Iine, the utility company should be noti- fied immediately. •Carefuily plan your sawing operation in advance. • Ctear the work area. You need a ciear area nil around the tree so you can have secure footing. • The chain saw operator shoutd keep on the uphill side of the terrain as the tree is likely to roll or slide downhill after it is felled. • Study the natural conditions that can cause the tree to fall in a particular di- rection. Natural conditions that can cause a tree to fail in a particular direction include: • The wind direction and speed. • The lean of the tree. The tean of a tree might not be apparent due to un- even or sloping terrain. Use a piumb or level to determine the direction of tree lean. • Weight and branches on one side. • Surrounding trees and obstactes. 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. Make sure there is enough room for the tree to fail Maintain a dis- tance of 2 _/2 tree lengths from the near- est person or other objects. Engine noise can drown out a warning call. Remove dirt, stones, loose bark, naiis, staples, and wire from the tree where cuts are to be made. Plan a ctear retreat path to the rear and diagonal to the line of fail FELLING LARGE TREES (6 inches (15 cm) in diameter or larger) The notch method is used to fell large trees. A notch is cut on the side of the tree in the desired direction of fall. After a felling cut is made on the opposite side of tree, the tree wiII tend to fail into the notch. NOTE: If the tree has large buttress roots, remove them before making the notch. If using saw to remove buttress roots, keep saw chain from contacting ground to prevent dulling of the chain. NOTCH CUT AND FELLING THE TREE • Make notch cut by cutting the top of the notch first. Cut through 1/3 of the diameter of the tree. Next compiete the notch by cutting the bottom of the notch. See iiiustration. Once the notch is cut remove the notch of wood from the tree. Final (felting) cut here, 2 inches (5 cm) above center of notch i' _.j.. Notch _ _t = • After removing the wood from the notch, make the felling cut on the op- posite side of the notch. This is done by making a cut about two inches (5 cm) higher than the center of the notch. This witt leave enough uncut wood between the felling cut and the notch to form a hinge. This hinge wili help prevent the tree from faliing in the wrong direction. Hinge holds tree on stump and helps control fall Opening of felling _ Plan a clear retreat path "_ - - = O "_ - Direction of Fal_ Closing of notch NOTE: Before felling cut is complete, use wedges to open the cut if necessary to control the direction of fall. To avoid 11
kickback and chain damage, use wood or p}astic wedges, but never steel or iron wedges. • Be alert to signs that the tree is ready to fail: cracking sounds, widen- ing of the feI}ing cut, or movement in the upper branches. • As tree starts to fall stop saw, put it down, and get away quickly on your ptanned retreat path. • DO NOT cut down a partially fatten tree with your saw. Be extremely cautious with partially fallen trees that may be poody supported. When a tree doesn't falI comptetely, set the saw aside and pul} down the tree with a cable winch, bIock and tackle, or tractor. CUTTING A FALLEN TREE (BUCKING) Bucking is the term used for cutting a fallen tree to the desired tog size. dab WARNING: Do not stand on the tog being cut. Any portion can rott causing toss of footing and control, Do not stand downhill of the log being cut. IMPORTANT POINTS • Cut on}y one tog at a time. • Cut shattered wood very carefully; sharp pieces of wood could be f_ung toward operator. • Use a sawhorse to cut small logs. Never allow another person to hold the Iog white cutting and never hold the Iog with your teg or foot. • Do not cut in an area where _ogs, timbs, and roots are tangled such as in a blown down area. Drag the togs into a ctear area before cutting by putHng out exposed and cIeared togs first. TYPES OF CUTTING USED FOR BUCKING _WARNING: If saw becomes pinched or hung in a log, don't try to force it out. You can tose 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. Restart the saw and carefully reenter the cut. To avoid kickback 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. Use a wedge to remove pinched saw Turn saw OFF and use a plastic or wooden wedge to force cut open. Overcutting begins on the top side of the log with the bottom of the saw against the _og. When overcutting use light downward pressure, 6% Undercutting: Undercutting involves cutting on the underside of the log with top of saw against the _og. When undercutting use light upward pressure.

Using a log for support f/1 st Cut Using a support stand 2 nd Cut X L LIMBING AND PRUNING _IIWARNING: Be alert for and guard against kickback. Do not allow the moving chain to contact any other branches or objects at the nose of the guide bar when limbing or pruning. Al- lowing such contact can resutt in serious injury. _iI_WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log, or in any posi- tion which can cause you to lose your balance or control of the saw. IMPORTANT POINTS • Work slowly, keeping both hands firmty gripped on the saw. Maintain secure footing and balance. • Watch out for springpotes, SpringpoIes are smalt size limbs which can catch the saw chain and whip toward you or pull you off balance. Use extreme cau- tion when cutting small size limbs or slender material, • Be alert for springback. Watch out for branches that are bent or under pressure, Avoid being struck by the branch or the saw when the tension in the wood fibers is released. • Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them. LIMBING • Always timb a tree after it is cut down. OnIy then can limbing be done safely and properly. • Leave the larger limbs underneath the fetted tree to support the tree as you work. • Start at the base of the foiled tree and work toward the top, cutting branches and limbs. Remove smaII limbs with one cut. • Keep the tree between you and the chain. Cut from the side of the tree op- posite the branch you are cutting. • Remove larger, supporting branches with the cutting techniques described in BUCKING WITHOUT A SUPPORT. • Always use an overcut to cut smalI and freety hanging limbs. Undercutting could cause limbs to fail and pinch the SaW. PRUNING _I'WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder, Get a professional to do the job. • Make your first cut 1/3 of the way through the bottom of the limb. • Next make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch (2,5 to 5 cm) collar from the truck of the tree, I • ,_r_ _ • , I sooondout "// Third ctt_/ Co,,ar _ V_,.__ First cut / Pruning technique 13
