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. 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.
