We do not recommend

the blade - but ifyou
do, be sure the blade is

An unbalanced
blade
will
cause eventual
damage
to 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.

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.
