How To Check 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
cutting performance decreases or the quality of
cut is poor, make the following changes.
1. When you mow, make sure the throttle
control is in the FAST position.
2. (Figure 6) Move the blade rotation control
(1) to the DISENGAGE position (8).
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. 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 authorized
service center.
6. Move the blade rotation control (1) to the
DISENGAGE position (8). Stop the engine.
Disconnect the wire from the spark plug.
7. (Figure 15) Check the operation of the
blade brake. Rotate the pulley with your
hand. Make sure that the brake pad (7) is
pressed tightly against the pulley.
WARNING: If the brake pad (7) does not
press tightly against the pulley, take the
unit to an authorized service centre.
8. (Figure 6) Move the blade rotation control
(1) to the ENGAGE position (9).
9. (Figure 15) Check the pads for the blade
brake (7). If the pads are excessively worn
or damaged, replace the brake pad
assemblies. Correct replacement parts and
assistance are available from an authorized
service center.
10. Attach the wire to the spark plug. Mow for a
short distance and again check the
operation of the blade rotation control.
11. When you move the blade rotation control to
the DISENGAGE position, all movement will
stop within five seconds. If there is
movement of the belt or the blades continue
to rotate, engage and disengage the blade
rotation control five times to remove any
excess rubber from a new mower drive belt.
If you need assistance, take the unit to an
authorized service center.
How To Check And Adjust The Clutch
(Figure 16)
If the motion drive belt is loose, the clutch will
slip when; going up a hill, pulling a heavy load,
or the unit will not move forward. Adjust the
clutch as follows.
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. 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).
4. Align the hole in the brake lever (5) with the
rear of the slot in the frame.
5. Push the clutch rod (6) toward the rear.
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
brake lever (5) and to the brake spring (3).
Fasten with the washer (2) and cotter
pin (1).
7. If the belt still slips after the clutch has been
adjusted, then the motion drive belt is worn
or damaged and must be replaced. See
“How To Replace The Motion Drive Belt”.
How To Check And Adjust The Drive
Brake (Figure 17)
1. The location of the drive brake is on the left
side of the gear box (see Figure 17).
2. Make sure the parking brake is set and the
automatic drive disconnect is in the PUSH
position (A, Figure 7).
3. Push the unit. If the rear wheels rotate,
adjust the brake pads as follows:
a. Release the parking brake.
b. Remove the brake arm spring (1) and
cotter pin (2) that secures the castle nut
(3).
c. Insert a 0.020 in. feeler gauge between
the brake rotor and top brake puck, then
set the brake by finger tightening or
loosening the castle nut.
d. Install a new cotter pin to secure the
castle nut, and then install the brake arm
spring.
e. Engage the parking brake.
f. Push the unit. If the rear wheels do not
turn, the drive brake is correctly adjusted.
g. Release the parking brake.
NOTE: If you cannot correctly adjust the
drive brake, replace the brake pads. Correct
replacement parts and assistance are
available from an authorized service center.
How To Remove The Battery (Figure 3)
To charge or clean the battery (1), remove the
battery (1) from the unit as follows.
WARNING: To prevent sparks,
disconnect the black battery cable (8)
from the negative (-) terminal before
you disconnect the red cable (5).
WARNING: The battery contains
sulphuric acid which is harmful to the
skin, eyes and clothing. If the acid
gets on the body or clothing, wash with
water.
1. Disconnect the black cable (8) from the
negative (-) terminal.
2. Disconnect the red cable (5) from the
positive (+) terminal (4).
3. To disconnect the battery retainer (2) from
the battery tray (3), push in on the lower
end of the battery retainer (2).
4. Remove the battery (1) from the right side
of the unit.
How To Charge The Battery (Figure 3)
WARNING: When you charge the
battery, do not smoke. Keep the
battery away from any sparks. The
fumes from the battery acid can cause an
explosion.
1. Before you charge the battery (1), remove
the battery (1).
2. To charge the battery (1), use a 12 volt
battery charger. Charge at a rate of 6
amperes for 1 hour.
3. Install the battery (1).
WARNING: To prevent sparks, fasten
the red cable to the positive (+) terminal
before you connect the black cable.
4. Fasten the red cable (5) to the positive (+)
terminal (4) with the fasteners as shown.
5. Fasten the black cable (8) to the negative
(-) terminal with the fasteners as shown.
6. Connect the battery retainer (2) to the
battery tray (3).
How To Level The Mower Housing
If the mower housing is level, the blade will cut
easier and the lawn will look better.
WARNING: Before you make an
inspection, adjustment, or repair to
the unit, disconnect the wire to the
spark plug. Remove the spark plug wire to
prevent the engine from starting by accident.
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tires. If the air
pressure is incorrect, the mower housing
will not cut level. The correct air pressure is
shown on the side of the tire.
3. Open the cover (5).
4. (Figure 18) Move the lift lever (1) to the
LEVEL ADJUSTMENT position (2).
5. (Figure 18 and 19) Loosen the front and
rear adjuster knobs (4). Make sure both
sides of the mower housing are sitting on a
flat surface. Also, make sure the lift links
and adjuster plates are loose and can easily
move up or down.
6. Tighten the front and rear adjuster knobs
(4). Make sure the adjuster knobs (4) are
tight. If necessary, use a wrench to tighten
the adjuster knobs (4). For plastic adjuster
knobs (4), tighten to a torque of 7 foot
pounds (9,5 Nm). For metal adjuster knobs
(4), tighten to a torque of 10 foot pounds
(13,5 Nm).
7. (Figure 20) Raise the lift lever (1) from the
LEVEL ADJUSTMENT position (2) to a
CUTTING HEIGHT position (3).
8. Close the cover (5).
9. Mow for a short distance. If the height of cut
is not level, repeat the above steps.
CAUTION: Do not operate with the mower
housing in the LEVEL ADJUSTMENT
position (2). If you operate in the LEVEL
ADJUSTMENT position (2), the mower
housing and blade will be damaged.
