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, re move
bottom oil drain plug.
• For engines with oil fi ll cap/dipstick,
remove bottom drain plug or remove en-
gine oil cap and turn mower on its side.
• After oil has drained completely, re place
oil drain plug and tighten se cure ly.
• Refi ll engine with oil. Pour slowly. Do
not overfi ll.
• Fill to top of slot inside of fi ller 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 fi lter.
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 specifi cations.
MUFFLER
Inspect and replace corroded muffl er as it
could create a fi re 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 fi nished 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, muffl er, air fi lter, and
carburetor are covered to keep water out.
Water in engine can shorten engine life.
SERVICE AND ADJUSTMENTS
CAUTION:
Before performing any
service or adjustments-
• Release operator presence control bar.
• Make sure the blade and all moving
parts have com plete ly stopped.
• Disconnect spark plug wire from spark
plug and place wire where it can not
come in con tact with plug.
LAWN MOWER
REAR DEFLECTOR (IF EQUIPPED)
The rear defl ector, attached between the rear
wheels of your mower, is provided to minimize
the pos si bil i ty that objects will be thrown out
of the rear of the mower into the operator
mowing position. If the defl ector becomes
dam aged, it should be replaced.
ENGINE
CARBURETOR
The carburetor has been preset at the fac-
tory and ad just ment should not be neces-
sary. However, minor ad just ment may be
required to compensate for differences in
fuel, temperature, altitude or load.
• The air fi lter must be assembled to the
car bu re tor 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. There fore, and assis-
tant will be required to hold the control bar
in the operating position when making fi nal
adjustment to the car bu re tor.
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 man ual.
