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 rubber.
• 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 qualified
service center.
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
hazardous, 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 & attaching hard ware
(bolt, lock wash er, hardened wash er).
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.
Recommended tightening torque: 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
the blade - but if you do, be sure the blade is
balanced. An un bal anced blade will cause
eventual damage to 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.
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail ex posed. 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 de te ri o ra tion. Through normal use
it will wear. If catcher needs replacing,
replace only with ap proved replacement
catcher shown in the Repair Parts section
of this manual. Give the lawn mower model
number when ordering.
GEAR CASE
• To keep your drive system work-
ing properly, the gear case and area
around the drive should be kept clean
and free of trash build-up. Clean under
the drive cover twice a season.
• The gear case is filled with lubricant to the
proper level at the factory. The only time
the lubricant needs attention is if service
has been performed on the gear case.
