LAWN MOWER
Always observe safety rules when perform-
ing any maintenance.
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 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. Ibs.
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.
ENGINE
Read the maintenance section of your
engine manual.
LUBRICATION
Change the oil after the first two hours of
operation and every 25 hours thereafter or
at least once a year if the lawn mower is
not used for 25 hours in one year. Refer to
engine manual.
TO CHANGE ENGINE OIL
(SEE ENGINE MANUAL)
• Be sure lawn mower is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• For engines without dipstick, remove
bottom oil drain plug.
• For engines with oil fill cap/dipstick,
remove bottom drain plug or remove en-
gine oil cap and turn mower on its side.
• After oil has drained completely, replace
oil drain plug and tighten securely.
• Refill engine with oil. Pour slowly. Do
not overfill.
• Fill to top of slot inside of filler hole or
to "FULE' line on dipstick on models so
equipped. Keep oil at proper level.

AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
Clean the element after every 25 hours of
operation or every season. Replace the air
filter every 100 hours of operation or every
season, whichever occurs first. Service air
cleaner more often under dusty conditions.
See the maintenance section of your
engine manual.
