LAWNMOWER
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 REMOVE BLADE
• Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with spark plug.
• Turn lawn mower on its side. Make
sure air filter and carburetor are up.
• 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 by turning counter-
clockwise. Use a 9/16" box or open-
end wrench.
• Remove blade and attaching hardware.
TO REPLACE BLADE
• Position the blade adapter on the
engine crankshaft. Be sure the spacer
is in the adaptor and key in shaft and
adaptor keyway are aligned.
• Position blade on the blade adapter.
Be sure the trailing edge of blade
(opposite sharp edge) is up toward the
engine.
• Install the blade bolt with washers into
blade adapter and crankshaft.
• 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. Ibs.
IMPORTANT: Blade bolt is grade 8 heat
treated.
TO SHARPEN BLADE
NOTE: We do not recommend
sharpening blade - but if you do, be sure
the blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause eventual damage to lawn mower or
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.
