LAWN MOWER
Always observe safety rules when per-
forming 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.
BLADE CARE
For best results, 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 filter 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).
6. Remove debris shield (if equipped).
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 dam-
aged.

gine crank shaft. Be sure key in adapter
and crankshaft keyway are aligned;
and that the drive belt is inside the tabs
of the belt retainer (if equipped).
2. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the 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.
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 file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
