CHAIN SHARPENING

Chain sharpening is a complicated task that requires special tools. We recommend that you refer chain sharpening to a professional chain sharpener.

CARBURETOR ADJUSTMENTS

WARNING: The chain will be moving during most of this procedure. Wear your pro- tective equipment and observe all safety pre- cautions. The chain must not move at idle speed.

The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions:

SChain moves at idle. See IDLE SPEED--T adjusting procedure.

SSaw will not idle. See IDLE SPEED--T ad- justing procedure.

Idle Speed--T

Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Adjust speed until engine runs without chain movement (idle too fast) or stalling (idle too slow). The idle speed screw is located in the area above the primer bulb and is labeled T.

STurn idle speed screw (T) clockwise to in-

crease engine speed.

STurn idle speed screw (T) counterclock- wise to decrease engine speed.

STORAGE

WARNING: Stop engine and allow 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. Store unit with all guards in place. Position so that any sharp object cannot accidentally cause injury to passersby. Store the unit out of reach of children.

SBefore storing, drain all fuel from the unit. Start engine and allow to run until it stops.

SClean the unit before storing. Pay particu- lar attention to the air intake area, keeping it free of debris. Use a mild detergent and sponge to clean the plastic surfaces.

SDo not store the unit or fuel in a closed area where fuel vapors can reach sparks or an

open flame from hot water heaters, electric motors or switches, furnaces, etc.

SStore in a dry area out of the reach of chil- dren.

CAUTION: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel fil- ter, fuel hose, or fuel tank during storage. Al- cohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to fuel mixture separation and formation of acids during storage. Acidic gas can damage the engine.
