TO SHARPEN BLADE (See Fig. 14)
Care should be taken to keep the blade balanced. An
unbalanced blade willcause 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 tosharpen while on the mower.
To check blade balance, you will need a 5/8" diameter
steel bolt, pin, or a cone batancer. (When using a cone
balancer, follow the instructions supplied with bal-
ancer).
Slide blade on to an unthreaded portion ofthe steelbolt
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.
