TO SHARPEN
BLADE
(See
Fig. 13)
NOTE: We do not recommend sharpening blade - but ifyou
do, be sure the blade is balanced.
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 g rinding
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, followthe 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 hodzontal
position.
If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.
