INSPECT MUFFLER AND SPARK ARRESTING SCREEN

WARNING: The muffler on this prod- uct contains chemicals known to the State of California to cause cancer.

As your unit is used, carbon deposits build up on the muffler and spark arresting screen and must be removed to avoid creating a fire haz- ard or affecting engine performance.

For normal homeowner use, the muffler and spark arresting screen will not require any service. After 50 hours of use, we recom- mend that your muffler be serviced or re- placed by an authorized service dealer.

CARBURETOR 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.
