CLEANING

IMPORTANT: For best performance,
keep mower housing free of built-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.

1. Release control bar and stop engine.

LAWN MOWER

TO ADJUST CUTTING HEIGHT
See “TO ADJUST CUTTING HEIGHT” in
the Operation sec tion of this manual.

REAR DEFLECTOR
The rear defl ector, attached between the
rear wheels of your mower, is provided to
minimize the possibility that objects will
be thrown out of the rear of the mower
into the operator mowing position. If the
defl ector becomes dam aged, it should be
replaced.

plug and place wire where it cannot
come in contact with plug.

2. Remove screws retaining drive cover

(not shown); and remove drive cover
from lawn mower housing.

3. Remove drive cable from anchor, then

detach it and return spring from idler

• Keep fi nished surfaces and wheels free

of all gasoline, oil, etc.

• We do not recommend using a garden

hose to clean lawn mower unless the
elec tri cal system, muffl er, air fi lter and
carburetor are covered to keep water
out. Water in engine can result in short-
ened engine life.

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.
