Air Cleaner Service
The air cleaner prevents
dirt
and dust from entering
the engine
through
the carburetor. It
is
very important
that the air cleaner filter be replaced if dirty, and prop-
erly installed at all times. This will prevent premature
wear
or
damage
to
the engine. A clean fi Iteralso avoids
starting and overheating problems.

Areas To Be Kept Clean
Your
equipment
has an air-cooled engine, so it is
important
that
air be able to circulate freely
to
keep the
engine cool while running. Always remove dirt, grass
and debris from the following areas: the cooling fins;
engine covers; the
air
intake screen just behind the
starter rope. Use a brush
for
thorough
cleaning regu-
larly. See Photo 5-5
for
reference. Also keep the air
holes in the center
of
the
front
cover
of
your
machine
clean. Always shut
off
the engine, make sure all parts
have stopped completely, and disconnect the spark
plug wire before cleaning these air holes. Use a small
wire
or
piece
of
coat hanger to unclog the
air
holes.
