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 wail. 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.
