INSPECT BLADE
WARNING: Before you inspect or remove the blade,
disconnect the wire to the spark plug. If the blade hits
an object, stop the engine. Check the unit for dam-
age. The blade has sharp edges. When you hold the
blade, use gloves or cloth material to protect your
hands.
If you keep the blade sharp and inspect the blade for damage, the
blade will cut better and be more safe to operate. Frequently check
the blade for excessive wear, cracks, or other damage. Frequently
check the nut that holds the blade. Keep the nut tight. If the blade
hits an object, stop the engine. Disconnect the wire to the spark plug.
See if the blade is bent or damaged. Check the blade adapter for
damage. Before you operate the unit, replace damaged parts with
original equipment parts. See the authorized service center in your
area. Every three years, have an authorized service person inspect
the blade or replace the old blade with an original equipment part.

blade adapter
according to the in-
structions for “Inspect Blade”. Replace a badly worn or dam-
aged
blade
with an original equipment blade. See an
authorized service center in your area.
5.
Clean the top and bottom of the mower housing. Remove all the
grass and debris.
6.
Mount the
blade
and
blade adapter
on the
mandrel
(Figure 11).
7.
Mount the
blade
so that the
hi--lift edges
are up. If the
blade
is upside down, the
blade
will not cut correctly and can cause
an accident.
8.
Fasten the
blade
with the original washers and
nut
. Make sure
the outside rim of the
Belleville washer
is against the
blade
(Figure 12).
WARNING: Always keep the nut tight that holds the
blade. A loose nut or blade can cause an accident.
9.
Tighten the
nut
that holds the
blade
to a torque of 35 foot
pounds (47,5 N--m).
10. Install the mower housing. See “How To Install The Mower
Housing”.

HOW TO SHARPEN THE BLADE
WARNING: Vibration can be caused if the blade is
not correctly balanced or if the blade is damaged. A
blade that is damaged with cracks can break and
cause an accident.
Keep a sharp edge on the
blade
. A
blade
that is not sharp will cause
the tips of the grass to become brown.
1.
Sharpen the
blade
two times a year or every 25 hours.
2.
Remove the
blade
according to the instructions in “How To Re-
move And Install The Blade”.
3.
Clean the
blade
with a brush, soap and water. Check the
blade
. Look for cracks, nicks, or other damage. Replace a
badly worn or damaged blade with an original equipment blade.
See an authorized service center in your area.
4.
Sharpen the
blade
with a
file
(Figure 13). Make sure you keep
the original bevel angle.
5.
Make sure the
blade
is balanced. Use a
screwdriver
and hold
the
blade
parallel to the
ground
(Figure 13). A
blade
that is
balanced will stay parallel to the
ground.
If the
blade
is not bal-
anced, the heavy end will rotate toward the
ground
. Sharpen
the heavy end until the
blade
is balanced.
6.
A new blade will cut better than a badly worn blade. Every three
years, have an authorized service person inspect the blade or
replace the old blade with an original equipment blade.
7.
Assemble the
blade
according to the instructions “How To Re-
move And Install The Blade”.
