Always observe safety rules when per-
forming any maintenance.
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 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.

kept sharp. Replace a bent or damaged

TO SHARPEN
BLADE
NOTE: We do not recommend sharpening
blade - but if you do, be su re blade is balanced.
Care should be taken to keep the blade bal-
anced. An unbalanced blade will cause even-
tual 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, drive a nail into
a beam or wall. Leave about one inch of
the straight nail exposed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
GRASS CATCHER
(if purchased as an accessory)
* The grass catcher may be hosed with
water, but must be dry when used.
. Check your grass catcher often for dam-
age or deterioration.
Through normal
use it will wear. If catcher needs replac-
ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
