AIR FILTER
Your engine will not run properly and may be damaged
by using a dirty air fi lter. Replace the air fi lter every 100
hours of operation or every season, whichever occurs fi rst.
Ser vice air cleaner more often under dusty conditions. See
the main te nance section of your engine manual.

or after every 100 hours of operation, whichever occurs

CLEANING
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with plug.
• 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
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.
