CARBURETOR IDLE SPEED ADJUSTMENT

WARNING: Keep others away when making idle speed adjustments. The chain will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. After making adjust- ments, the chain must not move at idle speed. The carburetor has been carefully set at the factory. Adjustment to the idle speed may be necessary if you notice any of the following conditions:

SEngine will not idle when the throttle is re- leased.

SThe chain moves at idle.

Make adjustments with the unit supported so the pruner is off the ground and the chain will not make contact with any object. Hold the unit by hand while running and making adjust- ments. Keep all parts of your body away from the chain and muffler.

S Turn idle speed screw clockwise to in- crease engine speed if engine stalls or dies.

S Turn idle speed screw counterclockwise to decrease engine speed if chain moves at idle.

WARNING: Recheck the idle speed after each adjustment. The chain must not move at idle speed to avoid serious injury to the operator or others.

FUEL SYSTEM

Under FUELING ENGINE in the OPERA- TION section of this manual, see message la- beled IMPORTANT regarding the use of ga- sohol in your engine.

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. Fol- low the mix instructions found on stabilizer container. Run engine at least 5 minutes after adding stabilizer.
