LAWN
MOWER
Always observe safety rules when per-
forming any maintenance.
TIRES
* Keep tires free of gasoline, oil, or insect
control chemicals which can harm rub-
ber.
* Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
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, be
sure to clean both front wheels.
1. Remove hubcaps, Iocknuts & washers.
2.
Remove wheels from wheel adjusters.
3. Remove any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel gear teeth.
4.
Put wheels back in place.
NOTE:
If after cleaning, the drive wheels
do not turn freely, contact a Sears or other
qualified
service center.
GEAR
CASE
* To keep your drive system working
properly, the gear case and area around
the drive should be kept clean and free
of trash build-up.
Clean under the drive
cover twice a season.
* The gear case is filled with lubricant to
the proper level at the factory.
The only
time the lubricant needs attention is if
service has been performed on the gear
case.
BLADE
CARE
For best results, mower blade must be
kept sharp.
Replace a bent or damaged
blade.
CAUTION:
Use only a replacement
blade approved by the manufacturer
of
your mower.
Using a blade not approved
by the manufacturer
of your mower is haz-
ardous, could damage your mower and
void your warranty.
TO REMOVE BLADE
1. Disconnect
spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Turn lawn mower on its side. Make
sure air filter and carburetor are up.
3. Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
NOTE:
Protect your hands with gloves
and/or wrap blade with heavy cloth.
4.
Remove blade bolt by turning counter-
clockwise.
5.
Remove blade and attaching hardware
(bolt, lock washer, hardened washer).

TO SHARPEN
BLADE
NOTE: We do not recommend
sharp-
ening blade - but if you do, be sure the
blade is balanced.
Care should be taken
to keep the blade balanced. An unbal-
anced blade will cause eventual damage
to mower or engine.
* The blade can be sharpened
with a file
or on a grinding wheel. Do not attempt
12
to sharpen while on the mower.
