TO SHARPEN BLADE (See Fig. 9)
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
unbalanced blade will cause excessive vibration and
eventual damage to mower and engine.
, The blade can be sharpened with afile 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" diame-
ter steel bolt, pin, or acone balancer. (When using a
cone baiancer, follow the instructions supplied with
balancer).
NOTE: Do not use a nail for balancing blade. The lobes
of the center hole may appearto be centered, but are not.
• Slide blade on to an unthreaded portion of the steel
bo]t 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.
