ing 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,
ddve 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.
