General Maintenance 61
Adjusting Arm Stowed Limit Switch
The Arm Stowed limit switch turns on the ARM EXTENDED warning light on the dashboard
(see Figure 3-52) when the operator extends the arm or closes the gripper. If this limit switch is
misaligned, the warning light may continue to flash even if the gripper is fully open and the arm is fully
retracted. The Arm Stowed limit switch also activates an audible alarm when the arm is out and the
vehicle speed is greater than about 3 mph (5 km/h).

Arm Stowed limit switch
This limit switch is located behind the left gripper finger when facing the arm.
To adjust the Arm Stowed limit switch:
1. Park the vehicle on safe, level ground.
2. Fully open the gripper and retract the arm alongside the body.
3. Adjust the limit switch in such a way that the ARM EXTENDED warning light on the dashboard
stop flashing when the gripper is fully open and the arm is fully retracted. To do this:
3 a. Loosen the limit switch nut.
3 b. Adjust the rod (see Figure 3-51) so that the gripper finger will trigger the limit switch (click
sound) and turn off the warning light.
