Adjusting the Tracking

Note: Determine the left and right sides of the machine
from the normal operating position.
1. Push both control levers forward the same distance.
2. Check if the machine pulls to one side.
Note: If it does, stop the machine and set the parking
brake.
3. Release the cushion from the rear of the machine.
4. Rotate the right cable adjustment to position the right
motion control in the center of the control panel
neutral-lock slot (Figure

2. Right motion-control lever
5. Rotate the left cable adjustment to match the left
wheel speed to the previously set right wheel speed.
6. Adjust in quarter-turn increments until the machine
tracks straight.
Note: Only adjust the left cable to match the left
wheel speed to the right wheel speed. Do not adjust
the right wheel speed as this will position the right
motion-control lever out of the center for the control
panel neutral-lock slot.

8. Repeat the cable adjustment until the tracking is
correct.
9. Check that the machine does not creep from neutral
with the park brakes disengaged.
Important: Do not rotate the linkage too far, as this
may cause the machine to creep in neutral.
Adjusting the Proximity Switch
Use this procedure if the machine will not start after adjusting
the tracking.
1. Ensure that the bolt attached to the motion-control
lever aligns with the proximity switch target
2. If needed, loosen the bolts and adjust the proximity
switch until the target aligns with the bolt attached to
the motion-control lever
3. Check the distance of the bolt to the proximity switch;
it needs to be between 0.51 to 1.02 mm (0.02 to 0.04
inches) as shown in
4. If adjustment is needed, loosen the jam nut and adjust
the bolt to the correct distance.
5. Tighten the jam nut after adjusting the bolt
6. Test the safety-interlock system before operation.
