SPARK PLUG

Replace spark plug at the beginning of each mowing season
or after every 100 hours of operation, whichever occurs
fi rst. Spark plug type and gap setting are shown in the
“PROD UCT SPEC I FI CA TIONS” section of this manual.

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.

CAUTION: To avoid serious injury, before
performing any service or adjustments:

1. Release control bar and stop engine.

2. Make sure the blade and all moving parts
have

completely

stopped.

3. Disconnect spark plug wire from spark

plug and place where it cannot come in

contact

with

plug.

IN-LINE FUEL FILTER (See Fig. 15)

The fuel fi lter should be replaced once each season. If fuel
fi lter becomes clogged, ob struct ing fuel fl ow to car bu re tor,
re place ment is re quired.

1. With engine cool, remove fi lter and plug fuel line sec-

tions.

2. Place new fuel fi lter in position in fuel line with arrow

pointing towards carburetor.

3. Be sure there are no fuel line leaks and clamps are

properly positioned.

4. Immediately wipe up any spilled gasoline.
