ing blade - but if you do, be sure the blade
is balanced.
TO SHARPEN BLADE
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause eventual damage to lawn mower or
engtne.
. 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,.
