Care should be taken to keep the blade balanced° An unbalanced blade will cause excessive vibration and even-

tual damage to mower and engine.,

oThe blade can be sharpened with a file or on a grinding 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 bal- ancer).

°Slide blade on to 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 horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.,

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not°
