General Recommendations
1. The owner’s responsibility is to maintain this
product. This will extend the life of the prod-
uct and is also necessary to maintain war-
ranty coverage.
2. Check the spark plug, drive brake, lubricate
the unit, and clean the air filter once a year.
3. Check the fasteners. Make sure all fasteners
are tight.
4. Follow the Maintenance section to keep the
unit in good operating condition.
WARNING: Before you make an in-
spection, adjustment, or repair to
the unit, disconnect the wire to the
spark plug. Remove the wire from the
spark plug to prevent the engine from
starting by accident.
NOTE: Torque is measured in foot pounds
(metric Nm). This measurement describes
how tight a nut or bolt must be. The torque is
measured with a torque wrench.
Inspect Blade
(Figure 13)
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 damage. The blade has sharp
edges. When you hold the blade, use
gloves or cloth material to protect your
hands.
If you keep the
blade
(1)
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 dam-
age. Frequently check the
nut (3)
that holds the
blade (1).
Keep the
nut (3)
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 (5)
for dam-
age. Before you operate the unit, replace dam-
aged 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.
How To Remove And Install The Blade
(Figure 13)
1. Remove the mower housing. See the instruc-
tions on “How To Remove The Mower Hous-
ing”.
2. Use a piece of wood to keep the blade from
rotating.
3. Remove the
nut (3)
that holds the
blade
(1)
.
4. Check the
blade (1)
and the
blade adapter
(5)
according to the instructions for “Inspect
Blade”. Replace a badly worn or damaged
blade
with an original equipment blade. See
an authorized service center in your area.
5. Clean the top and bottom of the mower hous-
ing. Remove all the grass and debris.
6. Mount the
blade (1)
and
blade adapter (5)
on the
mandrel (6).
7. Mount the
blade (1)
so that the
hi–lift edges
(7)
are up. If the
blade
is upside down, the
blade
will not cut correctly and can cause an
accident.
8. Fasten the
blade (1)
with the original
washers and
nut (3)
. Make sure the outside
rim of the
Belleville washer (2)
is against
the
blade (1)
.
WARNING: Always keep the nut (3)
tight that holds the blade (1). A
loose nut or blade can cause an
accident.
9. Tighten the
nut (3)
that holds the
blade (1)
to
a torque of 30 foot pounds (41,5 Nm).
10.Install the mower housing. See “How To Re-
move The Mower Housing”.
