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.
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 bolt by turning counter-
clockwise.
5. Remove blade and attaching hard-
ware (bolt, lock washer and hardened
washer).
TO REPLACE BLADE
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 (op-
posite sharp edge) is up toward the
engine.
3. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
4. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.
•The recommended tightening torque is
35-40 ft. Ibs.
IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts
section of this manual.

TO SHARPEN BLADE
NOTE: We do not recommend sharp-
ening the 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, 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.
RASS CATCHERG
oThe 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.
ENGINE
Maintenance, repair, or replacement of the
emission control 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 accord-
ing to your expected operating temperature.
