TO SHARPEN
BLADE
NOTE:
We do not recommend
sharp-
ening
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
excessive
vibration
and eventual
damage
to 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,
you will need a
5/8" diameter
steel bolt, pin, or a cone
balancer.
(When
using a cone balancer,
follow the instructions
supplied
with
balancer.)
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.
