TO CHANGE ENGINE OIL
(SEE ENGINE MANUAL)
• Be sure mower is on a level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• For engines without dipstick, remove
bottom oil drain plug.
• For engines with oil fill cap/dipstick,
remove bottom drain plug or remove en-
gine oil cap and turn mower on its side.
• After oil has drained completely, replace
oil drain plug and tighten securely.
• Refill engine with oil. Pour slowly. Do
not overfill.
• Fill to top of slot inside of filler hole or
to "FULl" line on dipstick on models so
equipped. Keep oil at proper level.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
Clean the element after every 25 hours
of operation, more often if lawn mower is
used in very dusty, dirty conditions.
See the maintenance section of your
engine manual.
SPARK PLUG
Change the spark plug once a year to
make the engine run better and easier
to start. Set spark plug gap according to
engine manual specifications.
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
CLEANING
IMPORTANT: For best performance, keep
mower housing free of grass build-up and
trash. Clean the underside of your mower
after each use.
• Clean the underside of your lawn mower
by scraping to remove buildup 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 your lawn mower unless the
electrical system, muffler, air filter, and
carburetor are covered to keep water out.
Water in engine can shorten engine life.
_LCAUTION: Before performing any
service or adjustments-
. Release operator presence control bar.
• Make sure the blade and all moving
parts have completely stopped.
• Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
LAWN MOWER
REAR DEFLECTOR (IF EQUIPPED)
The rear deflector, attached between the rear
wheels of your mower, is provided to minimize
the possibility that objects will be thrown out
of the rear of the mower into the operator
mowing position. If the deflector becomes
damaged, it should be replaced.
ENGINE
CARBURETOR
The carburetor has been preset at the fac-
tory and adjustment should not be neces-
sary. However, minor adjustment may be
required to compensate for differences in
fuel, temperature, altitude or load.
• The air filter must be assembled to the
carburetor when running engine.
• Best carburetor adjustment is obtained
when fuel tank is 1/4 full.
• In order for the engine to run, the operator
presence control bar must be held in the
operating position. Therefore, and assis-
tant will be required to hold the control bar
in the operating position when making final
adjustment to the carburetor.
See the ADJUSTMENT section of your
engine manual for further instructions.
ENGINE SPEED
The engine speed has been factory set.
Do not attempt to increase engine speed
as it may result in personal injury. If you
believe the engine is running too fast
or too slow, take your lawn mower to an
authorized engine service center for repair
and adjustment.
THROTTLE CONTROL
If it becomes necessary to adjust or re-
place the throttle control, see the ADJUST-
MENT section of your engine manual.
