CLEAN AIR FILTER
A dirty air filter decreases engine per-
formance and increases fuel con-
sumption and harmful emissions. Al-
ways clean after every 5 hours of
operation.
1. Clean the cover and the area
around it to keep dirt from falling into
the carburetor chamber when the
cover is removed.

button (see illustration). Remove
air filter.
NOTE: To avoid creating a fire hazard
or producing harmful evaporative
emissions, do not clean filter in gaso-

INSPECT MUFFLER AND SPARK
ARRESTING SCREEN
,_WARNING: The muffler on this
product 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 arrest-
ing screen. For normal homeowner use,
however, the muffler and spark arresting
screen will not require any service.
After 50 hours of use, we recommend
that your muffler be serviced or re-
placed by your Sears Service Center.

ensure the engine starts easier and
runs better. Set spark plug gap at
0.025 inch. Ignition timing is fixed and
nonadjustable.

2. Remove spark plug from cylinder
and discard.
3. Replace with Champion RCJ-6Y
spark plug and tighten securely with
a 3/4 inch (19 mm) socket wrench.
