TACT WITH THE SPARK PLUG,
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.
