Always
observe
safety
rules when per-
forming
any maintenance.
TIRES
• Keep tires free of gasoline,
oil, or insect
control chemicals
which can harm rubber.
• Avoid
stumps,
stones,
deep ruts, sharp
objects
and other
hazards
that may
cause tire damage.
BLADE
CARE
For best results,
mower
blade must be kept
sharp.
Replace
bent or damaged
blades.
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.

Disconnect
spark plug wire from spark
plug and place wire where
it cannot
come
in contact
with plug.
2.
Turn lawn mower on its side. Make
sure air filter and carburetor
are up.
3.
Use a wood
block between
blade and
mower
housing
to prevent
blade from
turning
when
removing
blade bolt.
NOTE:
Protect
your hands with gloves
and/or wrap blade with heavy cloth.

TO SHARPEN
BLADE
NOTE:
We do not recommend
sharp-
ening the blade - but if you do, be sure
the blade is 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 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
• The grass catcher
may be hosed with
water,
but must be dry when used.
• Check your grass catcher
often for dam-
age or deterioration.
Through
normal
use it will wear.
If catcher
needs
replac-
ing, replace
only with approved
replace-
ment catcher
shown
in the Repair
Parts
section
of this manual.
Give the lawn
mower model
number
when ordering.
ENGINE
Maintenance,
repair, or replacement
of the
emission
control devices and systems,
which
are being done at the customers
expense,
may be performed
by any non-road
engine
repair establishment
or individual.
Warranty
repairs
must be performed
by an authorized
engine
manufacturer's
service
outlet.

NOTE:
Multi-viscosity
oils (5W30,

etc.) improve
starting
in cold weather,
and
you should
check your engine
oil level fre-
quently
to avoid possible
engine
damage
from running
low on oil.
Change
the oil after every 25 hours of opera-
tion or at least once a year if the lawn mower
