As your unit is used, carbon deposits build up on the muffler and spark arresting screen. For normal homeowner use, however, the muffler and spark arresting screen will not re- quire any service. After 50 hours of use, we recommend that your muffler be serviced or replaced by your authorized service dealer.

CARBURETOR ADJUSTMENT

WARNING: Keep others away when making idle speed adjustments. The blade will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. When making adjust- ments, use a screwdriver short enough to keep your hands behind the handguard and away from the blade. After making adjust- ments, the blade 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:

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

SThe blade moves at idle.

Keep others away when making idle speed adjustments. Make adjustments with the unit resting on a level surface free of debris that can be caught in the hedge trimmer blade. Serious injury to the operator and others can occur if the carburetor is not properly adjusted. Keep all parts of your body away from the blade and muffler.

Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine runs without blade moving (idle too fast) or en- gine stalling (idle speed too slow).

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

STurn idle speed screw counterclockwise to decrease engine speed if the blade moves at idle.

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