TO SHARPEN BLADE
NOTE: We do notrecommend sharpen-
ing blade - butif 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 gdndingwheel. Do not attempt
to sharpen while on the mower.
To check blade balance, you will need
a 5/8" diameter steelbolt, pin, or a cone
balancer. (When using a cone bal-
ancer, follow the instructionssupplied
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
portionof the steel bolt or pin and hold
the bolt or pin parallel with the ground.
If blade is balanced, it shouldremain in
a horizontal position, if either end of
the blade moves downward, sharpen
the heavy end untilthe blade is
balanced.
