MUFFLER
Inspect and replace corroded muffl er as it could create a
fi re 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
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 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, muffl er, air fi lter and carburetor
are covered to keep water out. Water in engine can
result in shortened engine life.
WATER WASHOUT FEATURE (See Fig. 17)
Your lawn mower is equipped with a fi tting that allows quick
and easy cleaning of the underside of the housing. To use
this feature, proceed as follows:
1. Move lawn mower to an area of cut grass or another
hard surface.
NOTE: Water, grass and other debris will drain from beneath
the mower housing during the washout process.
2. Remove grass catcher and discharge chute assembly
from lawn mower.
3. Close mulcher door (if equipped).
4. Connect a garden hose to the fi tting where shown.
IMPORTANT: BE SURE THE GARDEN HOSE IS NOT ROUTED
UNDER THE LAWN MOWER HOUSING OR ENTANGLED IN
THE WHEELS.
5. Turn on water supply and check for leaks at the fi t-
ting.
If no leaks are present, start engine (as described in the
Operation section of this manual) and let engine run until
the underside of the lawn mower is clean.
WARNING: Do not engage the drive
system during the washout process.
6. Shut off the engine.
7. Shut off water supply and remove hose from fi tting.
CAUTION: Do not remove hose from
fi tting while engine is running. Water
in engine can result in shortened en-
gine life.
8. Start engine (as described in the Operation section
of this manual) and let engine run for a full minute to
remove excess water from mower.
