CLEANING
IMPORTANT:  FOR BEST PERFORMANCE, KEEP MOWER 
HOUSING FREE OF BUILT-UP GRASS AND TRASH.  CLEAN 
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

•      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/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 
fi lter and carburetor are covered to keep water out. 
Water in engine can result in shortened engine life.

Clean under drive cover at least twice a season. Scrape un-
derside of cover with putty knife or similar tool to remove any 
build-up of trash or grass on underside of drive cover.
