_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.
REPLACE
SPARK PLUG
Replace the spark plug each year to
ensure the engine starts easier and
runs better. Set spark plug gap at
0.025 inch. Ignition timing is fixed and
nonadjustable.
