pressurized air to clean or dry cartridge.

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.
_LCAUTION: 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 sea-
son. Scrape underside of cover with putty
knife or similar tool to remove any build-up
of trash or grass on underside of drive cover.
i, WARNING: To avoid serious injury, before performing any service and 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 wire where it cannot come in
contact with plug.

See "TO ADJUST CUTTING HEIGHT" in
the Operation section of this manual.
REAR DEFLECTOR
The rear deflector, 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
deflector becomes damaged, it should be
replaced.
