Stop switch must be pushed down to start or restart engine. 19. THROTTLE TRIGGER controls engine speed. 11. SAFETY TRIGGER prevents accidental acceleration of the engine. Throttle trigger (19) cannot be squeezed unless the safety latch is depressed. 17. RED CHOKE LEVER aids in starting the engine. 5. CHAIN BRAKE® LEVER / HAND GUARD protects the operator’s left hand in the event it slips off the front handle while saw is running. CHAIN BRAKE® is a safety feature designed to reduce the possibility of injury due to kickback by stopping a moving saw chain in milliseconds. It is activated by the CHAIN BRAKE® lever 2. LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of kickback, due to specially designed depth gauges and guard links. 20. CHAIN CATCHER reduces the danger of injury in the event saw chain breaks or derails during oper ation. The chain catcher is designed to intercept a whipping chain. 3. CHAIN SAW ADJUSTMENT SCREW It is normal for a new chain saw chain to stretch after the first 30 minutes of use. Check the tension of the chain regularly to ensure the best performance, see SAW CHAIN ADJUSTMENT under MAINTENANCE AND REPAIR INSTRUCTIONS. 7 A B B C A B B C RULES FOR SAFE OPERATION KICKBACK SPECIFICS KICKBACK SPECIFICS Kickback can lead to WARNING: dangerous loss of control of the chain saw and result in serious or fatal injury to the saw operator or to anyone standing close by. Always be alert. Rotational kickback and pinch-kickback are major chain saw operational dangers and the leading cause of most accidents. KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator. Any of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Rotational Kickback 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. BA AA A = Kickback path B = Kickback reaction zone Fig. 1 Pinch Kickback Pinch kickback can occur when the saw chain is pinched along the bottom or top of the guide bar. When pinched on the bottom of the guide bar, it may pull the saw forward, away from the operator When pinched along he top of the guide bar, it may push the guide bar rapidly back toward the operator.

Be sure to use fresh (less than 60 days old) clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture. Definition of Blended Fuels Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate and lead to formation of acids during storage. When using alcohol- blended fuel, use fresh fuel. Using Blended Fuels If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions: • Always use the fresh fuel mix explained in your operator's manual • Always shake the fuel mix before fueling the unit • Drain the tank and run the engine dry before storing the unit Using Fuel Additives The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion and minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit. If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as STA-BIL® Gas Stabilizer or an equivalent. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according to the instructions on the container. NEVER add fuel additives directly to the unit's fuel tank. For proper engine CAUTION: operation and maximum reliability, pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine. To Obtain Correct Fuel Mix: Thoroughly mix the proper ratio of 2-...
