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 rear 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 rear wheels.
BLADE CARE
For best results, mower blade must be
kept sharp.
Replace a bent or damaged
blade.
A 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 bolts by turning coun-
ter-clockwise.
5. Remove blade and blade adapter.

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 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, 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
• 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.
