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 unbalanced blade will cause

eventual damage to lawn mower or

engine.

•The 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, drive a nail into a beam or wall. Leave about one inch of

the straight nail exposed. Place center hole of blade over the head of the nail.

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. Blade
