AIR FILTER

be damaged by using a dirty air fiJter. Rein
place the air filter every 100 hours of op-
eration or every season, whichever occurs

dusty conditions. Do not wash air filter.
IMPORTANT: For best performance, keep
mower housing free of builbgrass and
trash. Clean the underside of your mower
after each use.
_il.CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
o Clean the underside of your lawn mower
by scraping to remove build_up of grass
and trash.
o Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
o Keep finished surfaces and wheels free
of all gasoline, oil, etc.

hose to clean lawn mower unless the
electrical system, muffler, air filter and
carburetor are covered to keep water
