• Clean the underside of your lawn mower by scraping
to remove build-up of grass and trash.
• Clean engine often to keep trash from accumulating. A
clogged engine runs hotter and shortens engine life.
• Keep fi nished surfaces and wheels free of all gasoline,
oil, etc.
• We do not recommend using a garden hose to clean
lawn mower unless the electrical system, muffl er, air
lter and carburetor are covered to keep water out.
Water in engine can result in shortened engine life.
