MAINTENANCE
LAWN MOWER
Always observe safety rules when performing any main-
tenance.
TIRES
•
Keep tires free of gasoline, oil, or insect control chem-
icals which can harm rubber.
•
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
bent or damaged blades.
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
hazardous, could damage your mower
and void your warranty.

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 and hardened washer).
TO REPLACE BLADE (See Fig. 15)
1.
Position blade on the blade adapter aligning the two
(2) holes in the blade with the raised lugs on the
adapter.
2.
Be sure the trailing edge of blade (opposite sharp edge)
is up toward the engine.
3.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
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 damage or deterio-
ration. Through normal use it will wear. If catcher needs
replacing, replace only with approved replacement
catcher shown in the Repair Parts section of this manual.
Give the lawn mower model number when ordering.
ENGINE
Maintenance, repair, or replacement of the emission con-
trol devices and systems, which are being done at the
customers expense, may be performed by any non-road
engine repair establishment or individual. Warranty repairs
must be performed by an authorized engine manufacturer's
service outlet.
LUBRICATION
Use only high quality detergent oil rated with API service
classification SG-SL. Select the oil's SAE viscosity grade
according to your expected operating temperature.
