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.)
