MUFFLER

Inspect and replace corroded muffler as it

could create a fire hazard and/or damage.

SPARK PLUG

Replace spark plug at the beginning of

each mowing season or after every 100
hours of operation, whichever occurs
first. Spark plug type and gap setting
are shown in the “PRODUCT SPECIFIC

ATIONS” section of this manual.

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.
