TO SHARPEN BLADE (See Fig. 14)
NOTE: We do not recommend sharpening blade - but if
you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced. An un-
balanced blade will cause excessive vibration and eventual
damage to mower and engine.
• " The bladecan be sharpened with a file or on a grind-
ing 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
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 unth readed 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 untilthe blade is balanced.
