TO SHARPEN
BLADE
NOTE:
We do not recommend
sharpening
your mower
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 mower
or engine.
o The blade can be sharpened
with a file
or on a grinding
wheel.
Do not attempt
to sharpen
while on the mower.
o 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.
GRASS
CATCHER
o The grass catcher
may be hosed
with
water,
but must be dry when
used.
o Check
your grass catcher
often for dam-
age or deterioration.

If catcher

ing, replace
only with approved

ment catcher
