TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
DRIVE WHEELS
Check 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
or dust cover area and must be cleaned to
free drive wheels.
If necessary to clean the drive wheels, be
sure to clean all wheels.
1. Remove hubcaps, Iocknuts, and wash-
ers.
2.
Remove wheels from wheel adjusters.
3. Remove any trash or grass cuttings
from inside the dust cover, pinion and/

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.

sharp.
Replace a bent or damaged blade.

ardous, could damage your mower and
void your warranty.

gine crankshaft.
Be sure key in adapter

keyway are aligned;
and that the drive belt is inside the tab
of the belt retainer.
2.
Install debris shield.
3.
Position blade on the blade adapter.
IMPORTANT:
To ensure proper assembly,

posite sharp edge) is up toward the
engine.
5.
Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.

TO SHARPEN
BLADE
NOTE: We do not recommend
sharpening
blade - but if you do, be sure the blade is
balanced.
An unbalanced
blade will cause
eventual damage to lawn mower or engine.
• The blade can be sharpened
with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer.
(When using a cone balancer,
follow the instructions
supplied with it.)
NOTE:
Do not use a nail for balancing
blade. The lobes of the center hole may
inside hub of blade adapter. 13 appear to be centered, but are not.
