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 "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 finished surfaces / wheels free of gasoline, oil, etc.
• With the exception of the water washout port (if
equipped), we do not recommend using a garden
hose to clean the outside of your lawn mower unless
the elec tri cal system, muffler, air filter and carburetor
are covered to keep water out. Water in engine can
result in shortened engine life.
