5 hours of operation.

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

lease air filter cover.

To avoid creating a fire hazard or
producing harmful evaporative emissions, do
not clean filter in gasoline or other flammable

MUFFLER AND SPARK ARREST-
ING SCREEN

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.

tion timing is fixed and nonadjustable.
