CLEANING
iMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN
THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

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 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 season. Scrape
underside of cover with putty knife or similar tool to remove
any build-up of trash or grass on underside of drive cover.
WATER WASHOUT FEATURE (See Fig. 16)
Your lawn mower is equipped with a fitting 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 fitting 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 fit-
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 |
i
system during the washout process.
!
6. Shut off the engine.
7. Shut off water supply and remove hose from fitting.
&
CAUTION: Do not remove hose from
fitting while engine is running. Water
in en.gine can result in shortened en-
gine life.
