Care should be taken to keep the blade
balanced. An unbalanced blade will cause
eventual damage to lawn mower or motor.
• 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 intoa
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, itshould remain in a horizontal
position.. If either end of the blade moves
downward, sharpen the heavy end until the
blade is balanced.
