• Turn mower on its side with carburetor and air filter
up.
• Clean the underside of your mower after each use
by scraping to remove build-up of grass clippings,
leaves, dirt or other matter. If this debris is allowed
to accumulate, it will invite rust and corrosion, and
may prevent proper mulching.
• Clean your mower and engine often to keep build­
up of grass or debris from accumulating around
engine. A clogged engine runs hotter and shortens
engine life.
NOTE: We DO NOT recommend using a garden hose
to clean mower unless the electrical system, muffler,
air filter and carburetor are covered to keep water out.
Water in engine can result in shortening engine life.
