TO SHARPEN
BLADE
NOTE:
We do not recommend
sharp-
ening
blade-
but if you do, be sure the
blade
is 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,
you will need
a 5/8" diameter
steel bolt, pin, or a cone
balancer.
(When
using
a cone
balancer,
follow
the instructions
supplied
with it.)
NOTE:
Do not use a nail for balancing
blade.
The lobes
of the center
hole may
appear
to be centered,
but are not.
• Slide blade
on to an unthreaded
portion
of the steel bolt or pin and hold the
bolt or pin parallel
with the ground.
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.
