CARBURETOR IDLE SPEED ADJUSTMENT
WARNING: Keep others away when making idle speed adjustments. The trimmer head, blade or any optional attachment will be spinning during most of this procedure. Wear your protective equipment and observe all safe- ty precautions. After making adjustments, the trimmer head, blade or any optional attachment 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 released.
S The trimmer head, blade or optional attachment moves/spins at idle.
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 ad- justments. Keep all parts of your body away from the cutting attachment and muffler.
To adjust idle speed:
Allow engine to idle. Adjust speed until engine runs without trimmer head, blade or optional attachment moving or spinning (idle too fast) or stalling (idle speed too slow).
S Turn idle speed screw clockwise to increase engine speed if engine stalls or dies.
STurn idle speed screw counterclockwise to decrease engine speed if trimmer head, blade or optional attachment moves or spins at idle.
WARNING: Recheck the idle speed after each adjustment. The trimmer head, blade or optional attachment must not move or spin at idle speed to avoid serious injury to the operator or others.
