Safety Hat Snug: Fitting .__ Clothing Heavy Duty Gloves ,/ Safety Chaps Safety Shoes Figure 1 KNOW YOUR SAW • Read your operator's manual carefully until you completely understand and can follow all safety rules, precautions, and operating instructions before attempting to operate the unit. • Restrict the use of your saw to adult users who understand and can follow safety rules, precautions, and operating instructionsfound in this manual. PLAN AHEAD • Wear protective gear. Figure 1. Always use steel-toed safety footwear with non-slfp 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. Regu,ar users should have hearing checked regularly as chain saw noise can damage hearing. • Keep all parts of your body away from the chain when the engine is running. * Keep children, bystanders, and animals a minimum of 30 feet (10 meters) away from the work area. Do not allow other people or animals to be near the chain saw when starting or operating the chain saw. • Do not handle or operate a chain saw when you are fatigued, ill, or upset, or if you have taken alcohol, drugs, or medication. You must be in good physical condition and mentally alert. Chain saw work is strenuous. If you have any condition which might be aggravated by strenuous work, check with your doctor before operating a chain saw. • Do not attempt to use your chain saw during bad weather conditions such as strong wind, rain, snow, ice, etc., or at night. • Carefully plan your sawing operation in advance.Do not start cutting until you have a clear work area, secure footing, and, if you are felling trees, a planned retreat path. • Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Always replace the handguard immediately if it becomes damaged, broken, or is otherwise removed. • Keep the handles dry, clean, and free of oil or fuel mixture. • With the.engine stopped, hand cam/the chain saw with the muffler away from your body, and the guide bar and chain to the rear, preferably covered with a scabbard. HANDLE FUEL WITH CAUTION • Eliminate all sources of sparks or flame in the areas where fuel is mixed, poured, or stored. There should be no smoking, open flames, or work that could cause sparks. • Mix and pour fuel in an outdoor area, on bare ground; store fuel in a cool, dry, well-ventilated place; and use an approve, marked container for fuel. • Wipe up all spilled fuel before starting your saw. • Move at least 10 feet (3 meters) away from fuel and fueling site before starting the engine. • Do not smoke while handling fuel or while operating the saw. • Turn the engine off and let your saw cool in a noncombustible area, not on dry leaves, straw, paper, etc. Stowly remove fuel cap and refuel unit. • Store tool and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc SAFETY NOTICE Exposure to vibrations through prolonged use of gasoline powered hand units could cause blood vessel or nerve damage in the fingers, hands, and wrists of people prone to circulation disorders or abnormal swellings. Prolonged use in cold weatherhas been linked to blood vessel damage in otherwise healthy people. If symptoms occur such as numbness, pain. loss of strength, change in skin color or texture, or loss of feeling in the fingers, hands or wrists, discontinue the use of this unit and seek medical attention.An anti-vibrationsystem does not guaranteethe avoidanceof these problems.

Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use. WORKING • Operate the chain saw only in 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 saw 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 saw 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 compJeted. • Stop the engine before setting the saw down. • Keep fuel and oil caps, screws, and fasteners securely tightened. ,==niil, i GUARD AGAINST .. KICKBACK KICKBACK 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 hold the flywheel when servicing the clutch, structural damage to the flywheel can occur and cause the flywheel to burst. • Make certain the saw 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 the 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 attachments supplied or specifically recommended by the manufacturer. TRANSPORTING AND STORAGE • Stop the unit before transporting. • Allow the engine to cool, cover the bar and chain, and secure the unit before storing or transporting in a vehicle. • Empty the 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 fuel 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 reach of children. =. = - Kickback is a dangerous iii reaction that can lead to serious injury. WARNING: Rotation Kickback Path KICKBACK CAN OCCUR WHEN THE MOVING CHAIN CONTACTS AN OBJECT AT THE UPPER PORTION OF THE TIP OF THE 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 OF THESE 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.

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 tensioned. 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 kickback to occur. Cut one log at a time. Use extreme caution when re-entering a previous cut. Watch for shifting logs or other forces that could close i a ocutnot attempt plunge and pinch or fall intocuts. chain. Use the Reduced-Kickback Guide Bar and LowKickback Chain specified for your saw. i KICKBACK SAFETY _ • Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting i chain. Stand with your Figure 4. weight evenly balanced on both feet. Do not overreach. You could be drawn or thrown off balance and lose control of the saw. ° Do not cut above shoulder height. It is difficult to maintain control of saw above shoulder height, UNDERSTANDING I[[J[ILLtt FEATURES REACTIVE FORCES Pinch-Kickback and Pull-In occur when the chain is suddenly 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, Either reaction can result in loss of control and possible serious injury. • Pinch-Kickback - occurs when chain on top of guide bar is suddenly stopped. - rapidly drives saw straight back toward operator. ° Pull-In - occurs when the chain on the bottom of the guide bar is suddenly stopped. - pulls the saw rapidly forward, Jl= I= I • Handguard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar. • Position front and rear handlebars, designed with distance between handles 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 resistance in controlling the pivot of the saw back toward the operator if kickback occurs. * ANSI B175.1-1991 - Safety requirements for gasoline powered chain saws as set by the American National Standards Institute, Inc., Standard B!75.1-1991.

During cutting, keep the saw frame against the log. \ Figure 18 THROTTLE TRIGGER & LOCKOUT (Fig. 19) • The throttle trigger controls engine speed. At idle, a centrifugal clutch automatically disengages the chain. • The throttle lockout prevents unintentional activation of the throttle trigger. Also, the throttle lockout must be depressed before the throttle trigger can be depressed. Figure 21 CUTTING SPEED • Accelerate engine to full throttle before entering cut by squeezing the throttle trigger. • Never cut with engine at partial throttle speed. Throttle Lockout \ Front Saw Frame" Throttle OPERATION ._ /5"t .:_ _ Trigger I I Figure 19 CUTTING TECHNIQUES USE/TIPS • Cut wood only. Do not cut metal; plastics; masonry; men-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 small amount of dirt will quickly dull a chain and thus increase the possibility of kickback. To get the "feel" of using your saw before you begin a major sawing operation, practice cutting a few small logs using the following technique: • Accelerate engine to full throttle before entering cut by squeezing the throttle trigger. • Begin cutting with the saw frame against the tog. - 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 completed, 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. (Fig. 20 & 21) • Overcutting - begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. • Undercutting - begin on the under side of the tog with the top of the saw against the log; exert light pressure 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. -10- ii i i ii i i iii i i OPERATION - SAFETY ill| GENERAL SAFETY AVOID REACTIVE Pinch-Kickback WARNING: IF SAW BECOMES PINCHED OR HUNG IN A LOG, DO NOT 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. RESTART THE SAW AND CAREFULLY RE-ENTER THE CUT. TO AVOID KICKBACK AND CHAIN DAMAGE, DO NOT USE A METAL WEDGE. DO NOT ATTEMPT TO RE-START YOUR SAW WHEN IT IS PINCHED OR HUNG IN A LOG. KICKBACK CAN OCCUR WHEN THE MOVING CHAIN CONTACTS AN OBJECT AT THE UPPER PORTION OF THE TIP OF THE 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 CHAIN TO DIG INTO THE 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 OF THESE REACTIONS CAN CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. PINCH FORCES 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 extreme_ 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 cutting with the engine at full throttle and the front saw frame against the wood. • Use wedges made of plastic or wood, (never of metal) to hold the cut open. -11 - i i i ]Nil I I OPERATION iii i i,iii ii i iii TREE FELLING ..=Felling Direction 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 (HAMMER) TO FORCE THE FELLING CUT OPEN. THE WEDGE WILL HOLD THE FELLING CUT OPEN ALLOWING YOU TO REMOVE THE SAW. KEEP EVERYONE AWAY TREE IN ALL DIRECTIONS. DETERMINE FROM THE NATURAL FALL DIRECTION PROCEDURE Cut I / ;_/_ THE • Wind - A tree evenly balanced will fatl in the same direction the wind is blowing. • Lean - Use a carpenter's level or ptumb bobto determine if tree has a natural lean. A leaning tree will tend to fal! in direction of lean. • Shape - A tree will tend to fall towards side that is more heavily branched. • Other Factors - Contacting or nearby trees, buildings, or wires can influence the direction the tree will fall. I CUTrlNG Felling Cut I Top NOtch---.-..._, (Fig. 22) After determining the Natural Fa_l 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 telling cut. The felling cut should be 2 inches above the center point of the notch cut. Before the felling cut is complete, use wedges to open the cut when necessary to control the direction of the fall. Use wood or plastic wedges, buI 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, move ON/STOP switch to "Stop" position, set it down, and move quickly away from direction of fall. 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. Cut deeper in the notch side of the tree until tree starts to fall. -12- Figure 22 • 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 fal!. Do so by driving the wedges deeper into the felling cut. • Keep everyone away from the tree in aFIdirections and then seek professional help! NOTE: For trees less than 6 inches in diameter, make a single feilingcut on the side away from the direction of fall. Cut through until tree begins to fall. Then turn off saw, set it down, and move quickly away from direction of fall. OPERATION USE/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 !/2 tree lengths from the nearest person or other objects. Engine noise can drown out a warning call. • Remove dire, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made. • Plan to stand on the up-HI side when cutting on a slope. ° Plan a clear retreat path to the rear and diagonal to the line of fall. • If unsure about which way a tree will fal!, use the notch cutting method. • 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.

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 with a cable winch, block and tackle, or tractor. To avoid injury, do not cut down a partially fatlen tree with your saw. -13- Check the lean - Don't cut on lean side i ........................

BAR AND CHAIN ,lllllllrlll FUEL WARNING: GUIDE i 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 SAE 30 oil until you are able to obtain Craftsman brand. The oil output is automatically metered during operation. Your saw will use one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank. iiiii i i iiiii i iiiii ii i STABILIZER Fuel stabilizer is an acceptable alternative in minimizing the formation of fuet gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the fuel mix ratio found on the stabilizer container, run engine at least 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 AIR-COOLED engine oil is specially blended with fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer (such as Craftsman No. 33500) to your fuel tank. 40:1 2-CYCLE AIR-COOLED ENGINE OIL: CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oil is strongly recommended. This oil is specially blended with fuel stabilizers for increased fuel stability (extends fuel life up to 5 times longer) and reduced smoke. If CRAFTSMAN 40:1 2-cycle AIR-COOLED engine oi! is not available, use a good quality 40:1 2-cycle AiRCOOLED engine oi_ that has a recommended fuel mix ratio of 40:1. IMPORTANT! Do not use: GASOLINE The two-cycle engine on this product requires a fuel mixture of regular unleaded gasoline and a high quality 40:1 2-cycle AIR-COOLED engine oil for lubrication of the bearings and other moving parts. The correct fueVoi! m_xture is 40:1 _see Fue! Mixture Chart). Too little oil- or the incorrect oil type will cause poor performance and may cause the engine to overheat and seize. Gasoline and oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. * AUTOMOTIVE OIL . BOAT OILS (NMMA, BIA etc.) These oils do not have proper additives for 2-cycle AIRCOOLED 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 directty in the unit's fuel tank. 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 formation of acids during storage. Acidic gas can damage the fue! 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. FOR ONE GALLON: ° Pour 3.2 ounces of high quality, 40:1 2-cycted AIRCOOLED engine oil into an empty, approved one gallon gasoline container. • Add one galion of regular unleaded gasoline to the gallon container, then securely replace the cap. • Shake the container. • The mixture is now ready for use. Fuel stabilizer can be added at this time if desired; follow mixing instructions on the label.

If in doubt, read the section on flooded engine in the starting section of this manual prior to beginning any adjustments. If you are unsure about adjusting the carburetor or experience any problem while attempting this process, please call the 1-800 number listed on the front cover of this manual for further assistance. The carburetor has been adjusted at the factory for sea level conditions. Adjustments may become necessary if the unit 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 "Idle Speed Adjustment." • Saw will not idle. See "Idle Speed Adjustment" and "Low Speed Mixture Adjustment." • Engine dies or hesitates when it should accelerate. See "Acceleration Adjustment." • Loss of cutting power which is not corrected by air filter cleaning. See "High Speed Mixture Adjustment." CARBURETOR CAUTION: DO NOT TURN SCREWS TOO TIGHT; THIS WILL RESULT IN DAMAGE TO NEEDLE TIPS AND NEEDLE SEATS. IF CHAIN MOVES WHEN ENGINE IDLES, TURN IDLE SPEED SCREW COUNTERCLOCKWISE UNTIL CHAIN STOPS. ° Turn wise • Turn turn. • Turn THE CHAIN WILL BE MOVING DURING MOST OF THIS PROCEDURE. WEAR YOUR PROTECTIVE EQUIPMENT AND OBSERVE ALL SAFETY PRECAUTIONS. (Fig. 58) Very small adjustments can affect engine performance. It is important to turn the screw a very small amount per adjustment and test performance before making further adjustments. Each adjustment should be no more than the width of the slot in the adjusting screw. NOTE: Do not attempt to adjust the screw beyond the stops as damage can occur. WARNING: PRESETS If your engine will not start due to suspected improper carburetor adjustment, the following presets may be required.
