any maintenance.
TIRES
• Keep tires free of gasoline,
oil, or insect
control chemicals
which can harm rubber.

stones,
deep ruts, sharp
objects
and other
hazards
that may
cause
tire damage.
DRIVE
WHEELS
Check
rear drive wheels
each time you
mow to be sure they move freely.
The
wheels
not turning
freely means
trash,
grass cuttings,
etc., may be inside
the
drive wheel
and dust cover area and must
be cleaned
out to free drive wheels.
BLADE
CARE
For best results,
mower
blade must be kept
sharp.
Replace
a bent or damaged
blade.
A CAUTION:
Use only a replacement
blade approved
by the manufacturer
of
your mower.
Using a blade not approved
by the manufacturer
of your mower
is
hazardous,
could damage
your mower
and
void your warranty.

spark
plug wire from spark
plug and place wire where
it cannot
come in contact
with plug.
2.
Turn lawn mower

Use a wood
block between
blade and

blade from
turning
when
removing
blade bolts.
NOTE:
Protect
your hands
with gloves
and/or
wrap blade with heavy
cloth.

TO SHARPEN
BLADE
NOTE:
We do not recommend
sharpening
the blade - but if you do, be sure the blade is
balanced.
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.
13
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.
