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 7)
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 centre 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 7)
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 centre 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”.
How To Adjust The Blade Rotation
Control
WARNING: To prevent an injury, the
blade rotation control must operate
correctly.
In normal usage, the blade rotation control will
not require an adjustment. However, if the cut-
ting performance decreases or the quality of cut
is poor, make the following changes.
1. When you mow, make sure the throttle con-
trol in in the FAST position.
2.
(Figure 8) Move the blade rotation control to
the DISENGAGE position (1).
3. Stop the engine. Disconnect the wire from
the spark plug.
4. Check the blade(s). Keep a sharp edge on
the blade(s). A blade that is not sharp will
cause the tips of the grass to become brown.
5.
(Figure 9) Disconnect the blade drive
spring (2) from the blade control rod (1).
Move the blade drive spring (2) to the
middle hole
(4). This will increase the ten-
sion on the mower drive belt.
6. Attach the wire to the spark plug. Mow for a
short distance and again check the quality of
cut. If necessary, move the blade drive
spring (2) to the
bottom hole (5)
7. Again check the quality of cut. If the quality of
cut has not improved, replace the mower
drive belt. See “How To Replace The Mower
Drive Belt”. If the replacing the belt does not
correct the problem, take the unit to an auth-
orized service centre.
8. Move the blade rotation control to the DIS-
ENGAGE position. Stop the engine.
9.
(Figure 10) Check the operation of the blade
brake. Rotate the pulleys with your hand.
Make sure the brake pads (1) are pressed
tightly against the pulleys
WARNING: If the brake pads (1) do
not press tightly against the
pulleys, take the unit to an author-
ized service centre.
10.
(Figure 8) Move the blade rotation control to
the ENGAGE position (2).
11.
(Figure 10) Check the pads for the blade
brake (7). If the pads are excessively worn
or damaged, replace the brake pad assem-
blies. Correct replacement parts and assist-
ance are available from an authorized
service centre.
12. Attach the wire to the spark plug. Mow for a
short distance and again check the operation
of the blade rotation control.
13. When you move the blade rotation control to
the DISENGAGE position, all movement will
stop within five seconds. If there is move-
ment of the belt or the blades continue to ro-
tate, engage and disengage the blade
rotation control five times to remove any ex-
cess rubber from a new mower drive belt. If
you need assistance, take the unit to an
authorized service centre.
14.
(Figure 9) If you replace the mower drive
belt, move the blade drive spring (2) to the
top hole (3).
How To Adjust The Speed Control Pedal
(Figure 19)
If the unit will not go into REVERSE or if the unit
moves very slowly in REVERSE, adjust the
speed control pedal (1) as follows.
1. Stop the engine.
2. Set the parking brake.
3. Remove the hair pin (3) from the adjuster
nut (2). Disconnect the adjuster nut (2)
from the yoke assembly (4).
4. Rotate the adjuster nut one turn in the direc-
tion shown in Figure 19.
NOTE: Too much adjustment will cause
the REVERSE speed to be too fast and
the FORWARD speed to be reduced.
5. Attach the adjuster nut (2) to the yoke as-
sembly (4) with the hair pin (3).
6. To check the adjustment, drive the unit. If
the adjustment is correct, the unit will now go
into REVERSE.
NOTE: if you need assistance, go to the
nearest authorized Service Centre. They
have the equipment and experience to make
the adjustment.
How To Check And Adjust The Motion
Drive Belt
(Figure 12 and Figure 19)
If the motion drive belt is loose, the belt will slip
when; going up a hill, pulling a heavy load, or the
unit will not move forward.
IMPORTANT: Always operate with the engine
speed in the FAST position. If the engine
speed is in a slow or moderate position, the
engine and transmission can become too hot
and cause problems that are similar to a
loose motion drive belt.
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.
1. Check the routing of the motion drive belt.
Make sure the belt is installed correctly and
is inside all the belt guides.
2.
(Figure 12) Remove the cotter pin (1),
washer (2), and brake spring (3) from the
adjustable nut (4).
3. Disconnect the adjustable nut (4) from the
brake lever assembly (5) and the parking
brake latch (6).
4. Use the cotter pin (1) removed in step 2.
Hold the cotter pin(1) at the back of the slot
and move the brake lever assembly rearward
against the cotter pin (1). This will set a 1/8
inch (3 mm) gap (8) between the brake
lever assembly and the back of the slot.
5. Turn the adjustable nut (4) until the nut will
fit through the hole in the brake lever (5).
6. Assemble the adjustable nut (4) to the
parking brake latch (6), brake lever (5) and
brake spring (3). Fasten with the washer (2)
and cotter pin (1).
