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.
