Replace the air filter every year, more
often if you mow in very dusty, dirty
conditions.

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean the underside of your mower
after each use.
_I, CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
plug.
•Tum lawn mower on its side. Make sure air
filter and carburetor are up. Clean the
underside of your lawn mower by scraping
to remove buildup of grass and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep finished 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, muffler, air filter 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 underside of cover with putty
knife or similar tool to remove any buildup of
trash or grass on underside of drive cover.
