DRIVE WHEELS
Check front drive wheels each time before
you mow to be sure they move freely.
The wheels not turning freely means trash,
grass cuttings, etc. are in the drive wheel
area and must be cleaned to free drive
wheels.
If necessary to clean the drive wheels,
check both front wheels.
Remove hubcaps (if equipped), hairpin
cotters and washers (or flange Iocknut If
equipped with threaded axle) from both
drive wheels.
Remove wheels from wheel adjusters.
Remove any trash or grass cuttings
from inside the dust cover, pinion and/or
drive wheel gear teeth.
Put wheels back in place.
If after cleaning, the drive wheels do not
turn freely, contact your nearest
authorized service center.

ENGINE
Read the maintenance section of your
engine manual.
LUBRICATION
Change the oil after the first two hours of
operation and every 25 hours thereafter or
at least once a year if the lawn mower is
not used for 25 hours in one year. Refer
to engine manual.
TO CHANGE ENGINE OIL
(SEE ENGINE MANUAL)
Be sure lawn mower is on 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
engine 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
"FULU' 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 or every season. Replace the
air filter every 100 hours of operation or
every season, whichever occurs first.
Service air cleaner more often under dusty
conditions. See the maintenance section
of your engine manual.
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
SPARK PLUG
Replace spark plugs at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs first.
Set spark plug gap according to engine
manual specifications.
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.
GRASS CATCHER (IF SO EQUIPPED)
Grass catcher may be hosed with water
but must be dry when used.
_I,CAUTION: Under normal usage, the
catcher material is subject to deterioration
and wear and should therefore be checked
to ensure compliance with original
manufacturer specifications.
