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.
ACLCAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come into contact with spark 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 shortened 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.
ACLWARNING: 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 wire where it cannot
come into contact with spark plug.
