hours of continuous use. Tighten oil plug
securely each time you check the oil level.

mower or side of engine.
5. Slowly pour oil down the oil fi ll spout,
stopping every few ounces to check

before starting engine.
9. Re con nect spark plug wire to plug.

MUFFLER
Inspect and replace corroded muffl er as it
could create a fi re hazard and/or dam age.
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 C-
A 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 and 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.
