TO SHARPEN
BLADE (See Fig. 13)
Care should be taken to keep the blade balanced.
An
unbalanced blade will cause excessive vibration and even-
tual 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 bal-
ancer).
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.
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
