LAWN MOWER
Always observe safety rules when per-
form ing any main te nance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemi cals which can harm rub-
ber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
DRIVE WHEELS
Check front drive wheels each time be fore
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, locknuts & washers.
2. Remove wheels from wheel ad just ers.
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 qualifi ed
service center.
BLADE CARE
For best results, mower blade must be
kept sharp. Re place a bent or dam aged
blade.
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 fi
lter and carburetor are up.
3. Use a wood block between blade and
mower hous ing to prevent blade from
turning when re mov ing 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 wash er and hardened
wash er).
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter.
The key must be in good condition to work
properly. Replace adapter if damaged.
TO REPLACE BLADE
1. Position the blade adapter on the en-
gine crank shaft. Be sure key in adapter
and crankshaft keyway are aligned.
2. Position blade on the blade adapter.
IMPORTANT: To ensure proper as sem bly,
center hole in blade must align with star
on blade adapter.
3. Be sure the trailing edge of blade (op-
posite sharp edge) is up toward the
engine.
4. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
5. 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. lbs.
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 en-
ing blade - but if you do, be sure the blade
is balanced. An un bal anced blade will
cause eventual damage to lawn mower or
engine.
• The blade can be sharp ened with a fi le
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 bal anc er,
follow the in struc tions supplied with
bal anc er.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
