ENGINE FUEL MIXTURE • Your chain saw is powered by a two-cycle engine which requires a fuel mixture of =regular gasoline and a high quality engine oil specially made for 2-cycle, air-cooled engines. The internal design of the 2-cycle engin_ requires lubrication of moving" parts. Lubi:icatlon is provided whenyouuse the Tecomrnended mixture of gasoline and oi1. 1. USE THE FOLLOWING r MIXTURES: 'o, . SEARS #32-36555 1r_u.o" ENGINE OIL I • "' _ = ANYGOOD . GRADE __OR__ AIR-COOLED, • Gasoline-must be clean and not over two months• old. After a short period of • time, gasoline begins to chemically break down and will form compounds that can cause hard starting and damage in 2-cycle engines. • The correct measure of gasoline to oil is very important. --:Too much oil in the mixture will foul the spark plug. --Too little oil will cause the engine to overheat resulting in damage. FUEL -- _ 2-CYCLE ENGINE OIL 2. DO NOT USE THE FOLLOWING IN FUEL MIXTURES: _ OIL AUTOMOTI VE Does not have proper additives for 2;cycte engines and could cause damage. Burns too hot for 2-cycle engines; will shorten spark plug life and could • damage your engine. • • Mix the fuel thoroughly in a container since gasoline and oil do not readily combine. Do not try to mix fuel directly in the fuel tank. GASOHOL Alcohol absorbs moisture causing acids to form _hich will damage metal and rubber parts. 3. HOW 4. IMPORTANT TO MIX FUEL a. Use only recommended fuel mixtures. b. 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. c. Mix and store fuel in an approved, marked container. a. Pour one-half of the gasoline into an approved, marked container. Do not try to mix oil and gasoline directly in the fuel tank. b. Add entire measure of 2-cycleEngine Oil. c_ Mix. d. Add remainder of gasoline. e. Mix'thoroughly for one minute. POINTS d. 'Mix and pour fuel in a well.ventilated area. Gasoline vapors are harmful to your health and are a serious fire hazard. e. Avoid over lilling the fuel tank, Allow 3/4 inch for expansion.

Carefully study this section before you make the first cut with your new saw. You must understand what causes kickback, how :you can reduce the chance of kickback, and how you can remain in the best control of the saw it kickback does e. Operate the engine at full throttle for all cutting. If the chain is moving at a slower speed, there is greater chance for kickback to occur.. f. Use the Lo-Kick ® Guide Bar' and Guard Link Chain specified for your particular saw. These devices have been designed to reduce the possibility of kickback. g: Use extra caution if yoursaw is equipped with the Power Sharp ® System. The Power Sharp ® saw isequipped with a Lo-Kick ® ....Guide Bar and a Guard Link Chain. However, due to the chain requirements of the built-in sharpening mechanism, the kickback force from the Power Sharp ® chain may be greater than that from other Guard Link chains. Occur. •.1. WHAT CAUSES KICKBACK .... Kickback can happen when the moving chain contacts an object at the tip of the guide bar while the saw is being operated. This contact causes the chain to dig into the object and stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the saw.tip up and back at the operator. The operator can lose control of the saw and the cutting chain can cause serious injury if it ,_co._t'aats anypart:of thebody._ ., : " 3: HOW YOU_ CAN - MAINTAIN" THE BEST .,r ...........

NOTE: The hinge helps to keep the tree fromtwisting and falling in the wrong direction. d. Use a wedge if there is any chance that the tree will not fall in the desired direction. NOTE: Stop cutting before the felling cut is complete; use a wedge to open up the cut, e. Be alert for signs that the tree is ready to fall: 1.) cracking sounds 2.) widening of the felling cut 3.) movement in the upper branches. b. Make the felling cut onthe opposite side of the notch about 2" higher than the bottom of the notch. c. Leave enough uncut wood between the fell, _i0,g,__qutand the notch to form a hinge.
