CARE
For best results, mower blade must be
kept sharp.

blades.
TO REMOVE
BLADE
1. Disconnect
spark plug wire from spark
plug and place wire where
it cannot
come in contact
with spark 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
housing
to prevent
blade from
tuming
when removing
blade bolts.

Protect your hands with gloves
and/or wrap blade with heavy cloth.
4.

Be sure the
trailing edge of blade (opposite
sharp
edge) is up toward the engine and
install the blade bolts.

the
blade bolts, turning

36-44 ft. Ibs.
TO SHARPEN
BLADE
NOTE:
We do not recommend
sharpen-
ing 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 gdnding
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.
