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.
