CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-grass
and trash. Clean the underside of your
mower after each use.
ACAUTION: 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 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 short-
ened 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
build-up of trash or grass on underside of
drive cover.

1. Release control bar and stop engine.
2. Make sure the blade and all moving parts have completely stopped.
