is balanced, balanced. An unbalanced
blade will cause eventual damage to lawn
mower or engine,
° The blade can be sharpened with a fife
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.

water, but must be dry when used.

ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
