TO SHARPEN BLADE
NOTE: We do not recommend 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 gdnding wheel. Do not attempt
to sharpen while it ison the mower.
• To check blade balance, you will need
a 5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone bal-
ancer, follow the 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 onto 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 ina
horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
