harmful emissions. Always clean after every
5 hours of operation.

keep dirt from falling into the carburetor
chamber when the cover is removed.

MUFFLER AND SPARK ARREST-
ING 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 your authorized service dealer.

card.
