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.

With a basic understandingof kickback, you cen reducethe 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 obstructionthat your chain could hit while you are cuttingthrougha 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'schain sharpening and maintenance instructions. Check tension at regufarinterva{s 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. Do not attempt plunge cuts. Watchforshiftinglogsorotherforoesthatcouldclose a cut and pinch or fall into chain.

Inspect the saw and repair or replace parts as necessary. • Keep the chain cut of dirt and sand. Even a small amount of dirt wilt quickty dull a chain and thus increase the possibility of kickback. To get the _eel" of usingyour saw before you begin a major sawing opera, on, practice cutting a few small togs usingthe followingtechnique: • Accelerate engine to full throttle before entedng cut by squeezing the throttle trigger. t I I ,, I ,,,,,,,,,,,,,,, i iiii i iii ii i Begin cuttingw_ththe saw frame against the log. Keep engine at fullthrottle during cuttingprocedure. 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 thethrottle triggeras soonas the cutis completed, allowing the engine to idle. Ifyou run the unit at futl throttle without cutting,unnecessarywear can occurto the chain, bar, and engine. To avoid losing control when completingthe cut, do not put pressure on the saw dunngthe end of the cut. Stop engine before settingunitdownafter operation.

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 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 Tile 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 3"HE 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.

A leaning tree willtend to fall in direction of lean. • Shape - A tree willtend to fail towards sidethatis more heavily branched. • Other Factors- Contacting or nearbytrees, buildings, or wires can influence the direction the tree willfall. CUTTING PROCEDURE (Fig. 23 ) After determining the Natura! Fall Direction,the tree should be cul as foliows: 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 notchcut Remove notch of wood. On the side of the tree oppositethe notch cut, make the felling 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, but neversteel or iron, to avoid idckback 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, 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 directionof fall is acceptS, le, c_ietully re:. move the felling wedge, Cut deeper in me notchsioe ot the tree untiltree startsto fall. • If the wrong directionof falt is not ac.c. eptable,.a_empt.to use one or more felling wedges to mrce the tree in.me original direction of fall Do so by ddving the weoges deeper into the fellingcut, • Keep everyone away from the tree in all directionsand then seek professionalhelp!

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 avaJlable, you may use a goodgrade SAE30 oiluntil you are able to obtain Craftsman brand. The oil output is automaticallymetered during operation. Your saw willuse one tank of baroil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank. Fuel stabilizer isan acceptable alternative in minimizing the formationof fuel gum depositsdudngstorage.AddstabilLzer to gasoline in fuel tank or storage container.Always follow the fuel mix ratio found on the stabilizer container. Run engine at least 5 minutesafteradding stabilizerto allow the stabilizer to reach the carburetor.You do not have to drain the fuel tank for storage if you are usingfuel stabilizer. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is speciallyblended with fuel stabilizers.Ifyou do not use this Sears oil, you can add a fuel stabilizer (such as Craftsman No. 33500) to your fue! tank, 2-CYCLE OIL: CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) stronglyrecommended.This oilisspe_a|ly blendedwithfue| stabilizersfor increasedfuel stabilk'y(extendsfuel rffeupto 5 times longer) and reduced smoke. If CRAFTSMAN 40:1 2.cycle engine oil (AIR-COOLED) is not available, use a good quality 40:1 2-cycle engine oil (AIR-COOLED) engine oil thathas a recommendedfuel mix . ratio40:1. IMPORTAN'13 Do not use: • AUTOMOTIVE OIL • BOAT OILS (NMMA, BIA. etc.) These oils do not have proper additives for 40:1 2-cycle engine oil (AIR-COOLED) engines and can cause engine damage. GASOLINE The two-cycle engine on thisproductrequiresa fuel mixture of regular unleaded gasolineand a high quality40:1 2.-cycle engine oil (AIR-COOLED) for lubricationof the bearings and other moving parts. The correctfueVo_ mixture is40:1 (see Fuel Mixture Chart). Too t_le oil or the incorrect oiltype will cause poor performance and may causethe engine to overheat and seize. Gasoline and,oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. Thisengine hasbeen certified to operateon unleaded gasoline and Craftsman 40:1 2-cycle engine oil(AIR-COOLED). IMPORTANT: Experience indicates that alcohol blended fuels caIled gasohol (or using ethanol or methanol) can attract moisture, which leads to oiVgas 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, 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. GASOLINE AND OIL MIXTURE MIX GASOLINE AND OIL AS FOLLOWS: • Consult cha.,tfor correctquarr_ies. • Do not mix gasoline and oil directly in the fuel tank. FOR ONE GALLON: • Pour 3.2 ounces of high quality, 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 momentarily. o The mixture is now readyfor use. Fuel stabi{izercan be added at this time if desired;follow mixing ins'mJCtions on the label.
