Prolonged use in cold weather has 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 feelings in the fingers, hands or joints, discontinue the use of this tool and seek medical attention° An anti-vibralion system does not guarantee the avoidance of these problems. Users who operate power tools on a continual and regular basis must monitor closely their physical condition and the condition of this unit. LOOK FOR THIS SYMBOLTO POINT OUT IMPORTANT SAFETY PRECAUTIONS. IT MEANS - A'I-rENTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED. -2- SAFETY OPERATE YOUR SAW SAFELY ° Do not operate a chain saw with one hand. Serious injury to the operator, helpers, bystanders or any combination of these persons may result from 0ne-handed operation. 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 whencutting 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. GUARD _ AGAINST KICKBACK RULES MAINTAIN YOUR SAW IN GOOD WORKING , .• 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 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. ORDER TRANSPORTING:AND STORAGE -: Stopthe unitbefore.transporting. ° Allow engine to,cool,-c0ver 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 fuel vapors cannot reach sparks or open flames from water heaters, _ectric 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 reaction that can lead to serious injury. Kickback Path KICKBACK OCCUR WHEN THE MOVKICKBACK CAN WARNING: ING CHAIN CONTACTS AN OBJECT ATTHE UPPER PORTION OFTHE TIP OFTHE GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE CHAIN IN THE CUT. CONTACT AT THE UPPER PORTION ()F THE TIP OF THE GUIDE BAR CAN CAUSE THE CHAIN TO DIG INTO THE OBJECT, WHICH STOPS THE CHAIN FOR AN INSTANT.THERESULT 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. Figure 2 Avoid Obstructions Clear The Working Area Figure 3 -3- SAFETY Hand Positions Under Side O -- Elbow Locked Never __ Reverse _t_\ Stand To Thumb On Handlebar The Left Of The Saw _f_I_ Figure 4 REDUCE THE CHANCE OF KICKBACK * Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents. • Never let the m_oving 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 av_0idany obstructionthat 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 kickbackto 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. o 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. _o 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 LowKickback Chain specified for your saw. KICKBACK SAFETY FEATURES- RULES 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 encircling 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 straight line with your right hand on the rear handle 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 feet. • 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 balance and lose control of thesaw. • Do not cut above shoulder height. It is difficultto maintain control of saw above shoulder height. UNDERSTANDING REACTIVE FORCES Pinch-Kickback and PulHn occur when the chain is suddenly stopped by being pinched, caught, or by contacting 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 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. • Handguard, designed to reduce the chance of your left hand contacting the chain:if your hand slips off the front handlebar. ....... ,_ • Position of 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;_f the saw back toward the operator if kickback occurs. THE FOLLOWING FEATURES ARE INCLUDED ON YOUR SAW TO HELP REDUCE THE HAZARD *OF, KICKBACK; HOWEVER, SUCH FEATURES 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 MAINTENANCE IN THIS MANUAL TO HELP AVOID KICKBACK AND OTHER FORCES WHICH CAN RESULT IN SERIOUS INJURY. * ANSi B175.1-1991 - Safety requirements for gasoline powered chain saws as set by the American National Standards Institute, Inc., Standard B175.t-1991.

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_se a good grade SAE30 oil until you are able to obtain Craftsman brand. The oil output is automaticaUy metered during operation. Your saw will use approximately onetank'0f 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 unleaded gasoline and a quality 40:1 2_cycle engine oil (AIR-COOLED) for lubrication of the bearings and other moving parts. The correct fuel/oil mixture is 40:1 (see Fuel 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. 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 fuel system of amengine 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 is an acceptable alternative in minimizing the formation of fuel 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 engine oil (AIR-COOLED) is specially blended with fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer to your fuel tank. AiR-COOLED 40:1 2-CYCLE 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 fue! life up to 5 times longer) and reduced smoke. If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is not available, use a good quality 2-cycle engine oil (AIRCOOLED) that has a recommended fuet 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 quatity, 40:t 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 container momentar)ly: The mixture is now ready for _e. 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 Gasoline Oil {fl.oz.) 1 gallon 2.5 gallons 3.2 8.0 NOTE: Fuel containers may hold more than the specified amount. If too much gasoline is in the container, the resulting gas-to-oil fuel mixture will not be correct for proper engine operation. -10- OPERATION STOPPING YOUR ENGINE ' o Move on/stop switch to the "Stop" position. • If engine does not stop, pull blue choke knob out fully.

Do not cut metal; plastics; masonry; nonwood building materials; etc. • Stop lhe 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 incre&se 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 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 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. OPERATION SAFETY AVOID REACTIVE WARNING: IF SAW BECOMES PINCHED OR HUNG IN A LQG, 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. RESTARTTHE 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. KICKBACK CAN OCCUR WHEN THE MOVING CHAIN CONTACTS AN OBJECT ATTHE 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 WHICHKICKS 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 Pinch-Kickback and Pull-In occur when the chain is suddenly stepped 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. Pir,ch-Kickback drives the saw straight back toward the operator. Pull-In pulls the saw away from the operator. Either reaction can result in loss 6f control and possibly serious ihjury. 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 cutting with the engine at full throttle and the saw housing against wood_s: ° Use wedges made of plastic or.wood, (never of metal) to hold the cut open. -12- OPERATION TREE m 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, IFTHE 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 R EMOVE THE SAW. KEEP EVERYONE AWAY FROM THE TREE IN ALL DIRECTIONS. DETERMINE THE NATURAL PROCEDURE F ....... Bottom Notch Cut Cut t Buttress Root FALL DIRECTION • Wind - A tree evenly balanced wilt fall in the same direction the wind is blowing. • Lean - Use a carpenter's level or plumbbob to deter. mine if tree has a natural tean, A leaning tree will tend to fall in direction of lean. • • Shape - A tree wilt 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. CUTTING Felling Top Notch Cut (Fig. 12) After determining the Natura! 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) AVAI_BLE 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 idegree .angle until yoly meet the top notch cut. Remove notch of wood.' .... _.... ° On the side of the tree opposite the notch cut, make the felling cut. The fe!ling 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, 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 tall. -13- • .Ogure 12.: If your chain saw binds in the felling cut, you have three options: • if the wrong direction of fal! is acceptable, carefully remove the feffing wedge. Cut 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 • Clearthe 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, Ioose_bark,::nails,staples; and wire .._._fromthe .treewhere_cuts_m:_o be made, _ . ...... -.Plan to stand on the up-hill;side,when cutting on a slope. • .--Planaclearretreat_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 POSITIONS Check the wind Don't cut down wind I_ Check the lean Don't cut on down side DOARNING: NOT_CUT: - NEAR ELECTRICAL WIRES OR BUILDINGS. - IF YOU DO NOT KNOW THE DIRECTION OFTREE FALL. - AT NIGHT. - DURING BAD WEATHER - RAIN, SNOW, STRONG WIND, ETC. • Look for decay and rot. If the trunk is rotted, itcan snap and fal{ toward the operator. - Check for broken or dead branches which can fall on you while cutting. • Be extremehJ cautious with partially fallen trees that may be poody supported. When a tree doesn't fal! 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 fallen tree with your saw. -!4- Check the balance Don't cut on weighted side OPERATION BUCKING Bucking is cutting a fallen tree to the desired• log size. "I_nPES OF CU'I-rlNG (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 log with the top of the saw chassis against the log; exert light pressure upward. During undercutting, the saw will tend to push back at you. Be prep.ared for this reaction and hold the saw firmly to maintain control. 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 - Undercut 1/3 of the way through the log. - Finish with an ovemut. • Area B - Overcut 1/3 of the way through the log. - Finish with an undercut. 2nd Cut 2nd Cut 1st !1st Cut Sawhorse Saw Chassis Figure 13 BUCKING ON THE GROUND (Fig. 14) • Overcut with a 1t3 diameter cut. • Roll log over and finish with an overcut. Another Log Figure 16 BUCKING • Cut only one log at a time. • Cut shattered wood very carefully. 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_anarea where, logs, limbs, and roots are tangled suchas ina blown down area. Drag the logs into a clear area beforecutting 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. / Figure 14 OPERATION BUCKING TIPS SAFETY SAFETY WARNING: DO NOT STAND ON THE LOG BEING CUT'.

OPERATION PRUNING AND LIMBING SAFETY '_ "" SAFETY , Watch out for springpoles. Use extreme caution when cutting small size limbs. Slender material may catch the saw chain and be whipped' toward you or pull you off • balance. • Be alert for springback. Watch out for branches that are bent or under pressure as you are cutting to avoid being struck by the branch or the saw when the tension in the wood fibers is released. T _ AND LIMBING TIPS • Work slowly, keepingboth 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 support the tree as you work. • Start at the base of the fetled 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. NEVER CLIMB INTO A TREE TO LIMB OR WARNING: PRUNE UNLESS SPECIFICALLY TRAINED TO DO SO. DO NOT STAND ON LADDERS, PLATFORMS, A LOG, OR IN ANY POSITION WHICH CAN CAUSE YOU TO LOSE YOUR BALANCE OR CONTROL OFTHE SAW. 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 UMBING OR PRUNING. ALLOWING SUCH CONTACT CAN RESULT IN SERIOUS INJURY.

ALWAYS WEAR GLOVES WHEN HANDLING THE CHAIN. THE CHAIN CAN BE SHARP ENOUGH TO CUT YOU EVEN THOUGH IT IS TOO DULLTO CUTWOOD. CHAIN TERMINOLOGY Tools required: • Flat file • .025 depth gauge • 4.5mm round file & file holder Conditions which indicate the need for chain sharpening: • Reduction in size of wood chips. The size of the wood chip will decrease as the chain gets duller until it becomes more like a powder than a chip. Note that dead or rotted wood will not produce a good chip. • Saw cuts to one side or at an angle. • Saw requires excessive force to cut. • Noticeable loss of cutting speed. Sharpening instructions: • Move on/stop switch to the "Stop" position. • Check chain for proper tension. Adjust chain tension if necessary. (See Chain Tension/Adjustment). • Check and lower depth gauges before sharpening cutters. • Depth gauges should be checked every third sharpening. When cutting frozen wood!he depth gauges should be checked each time you_sharpen the chain_ • To check depth gauge, place gauge tool on cutter, If the depth gauge projects above the tool, then file it level to the top of the depth gauge tool.

Do not adjust for best power by sound or speed, but judge 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-o[ Jackspower while cutting. • Repeat the test cut. ° Continue with 1t16 turn adjustments until the saw performance is acceptable while cutting. • Aftercompleting 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 acceleration. • Check the idle speed for stability and no chain movement: Adjust as necessary. • Recheck for smooth acceleration and stable idle. RePeat process as necessary for acceptable performance. - 26 - STORAGE Immediately prepare your unit for storage at the end of the season or if it will not be used for 30 days or more. I_bb IMPORTANT: It is important to prevent gum deposits from forming in essential fuel System parts such as the carburetor, fuel filter, fuel hose or tank during storage. Also, experience 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 fuel system should be emptied before storage of 30 days or longer. 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 SWITCHES, FURNACES, ETC. . Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to the gasoline in the fuel tank or fuel storage container. Always follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor.
