LAWN MOWER
Always observe safety rules when
performing any maintenance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm
rubber.
• 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 bent or damaged
blades.
TO REPLACE BLADE
• Turn lawn mower. See engine manual
for proper direction of turning over the
engine.
• Use a wood block between blade and
mower housing to prevent blade from
turning when removing blade bolt.
• Protect your hands with gloves and/or
wrap blade with heavy cloth.
• Remove blade bolt, lock washer and flat
washer.
• Remove blade and blade adapter.
• Inspect the key inside blade adapter.
Replace adapter if damaged.
IMPORTANT: Blade bolt is grade 8 heat
treated.
• Install new or sharpened blade with
trailing edge up toward the engine.
• Position blade on blade adapter. Align
the two (2) holes in blade with raised
lugs of adapter.
• Reassemble blade bolt, lock washer
and flat washer into blade adapter and
crankshaft in exact order as shown.
• Position block of wood between blade
and mower housing.
• Tighten blade bolt securely. Recom-
mended tightening torque is 35-40 ft.

NOTE: We do not recommend sharpening
blade - but if you do, be sure the blade is
balanced.
TO SHARPEN BLADE
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
excessive vibration and eventual damage
to lawn mower and 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.

DRIVE COVER
Clean under the drive cover at least twice
a season. Scrape underside of cover with
a putty knife or similar tool to remove any
buildup of trash or grass.
GEAR CASE (GEAR DRIVE MODELS)
• To keep your drive system working
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.
• If lubricant is required, use only Texaco
Starplex Premium 1 Grease, Part No.
750369. Do not substitute.
