CARBURETOR ADJUSTMENT

WARNING: Keep others away when making idle speed adjustments. The trimmer head will be spinning during most of this pro- cedure. Wear your protective equipment and observe all safety precautions. After making adjustments, the trimmer head must not move/spin at idle speed.

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

S Engine will not idle when the throttle is re- leased.

SThe trimmer head moves/spins at idle speed.

Make adjustments with the unit supported so the cutting attachment is off the ground and 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 cutting attachment and muffler.

Idle Speed Adjustment

Allow engine to idle. Adjust speed until engine runs without trimmer head moving or spinning (idle speed too fast) or engine stalling (idle speed too slow).

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

STurn idle speed screw counterclockwise to decrease engine speed if trimmer head moves or spins at idle speed.

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