keep mower housing free of built-grass
and trash. Clean the underside of your
mower after each use.

o Clean the underside of your lawn
mower by scraping to remove buildmup
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
out. Water in engine can result in short-
