Adjusting Arm Stowed Limit Switch
The arm stowed limit switch illuminates the ARM OUT warning lights on the dashboard when the
operator extends the arm or closes the gripper. If this limit switch is misaligned, the warning lights on
the dashboard may continue to flash even if the gripper is fully open and the arm 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).
This limit switch is located behind the gripper’s right side fingers (see illustration above). On dual
H
ELPING-HAND™ units, the arm stowed limit switch on the street side is behind the gripper’s left side
finger.
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 OUT warning lights 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 so that the gripper’s fingers will trigger the limit switch (click sound) and
turn off the warning lights.
