TO SHARPEN BLADE

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 unbalancedblade will cause

excessive vibration and eventual damage to mower and engine.

•The blade can be sharpened with a file

or on a grindingwheel. Do notattempt to sharpen while it is 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 instructionssupplied with bal-

ancer).

NOTE: Do not use a nail.for balancing blade. The lobes of the center hole may appear to be centered, butare 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 in a hod- .

zontal position. If either end of the blade

moves downward, sharpen theheavy end untilthe blade isbaianced_
