Muffler
This unit must never be operated with a
faulty or missing spark arrester or muffler.
Make sure the muffler is well secured and
in good condition. A worn or damaged
muffler is a fire hazard and may also cause
hearing loss.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws) are
tight.
Prior to each work day, perform the
following:
■ Remove all dirt and debris from the
engine, check the cooling fins and air
cleaner for clogging, and clean as
necessary.
■ Carefully remove any accumulations of
dirt or debris from the muffler and fuel
tank. Dirt build-up in these areas can
lead to engine overheating, fire, or
premature wear.
