Axle Unlocked Alarm

To test the Axle Unlocked Alarm and Tipover
Hazard light do the following:

1. Start the engine from the ground control box

and stow the AB50J.

2. Use the Riser Boom switch to raise the riser

boom about 6 feet (2 m). The arm (1) of the
limit switch (2) at the end of the riser should
be up as shown.

3. Manually push the arm completely down then

operate Jib DOWN while holding switch.

4. Release the Jib DOWN switch, then release

the switch arm.

When you release the arm, the Axle Unlocked
Alarm should sound and the Tipover Hazard light
on the front of the platform control box should
come on.

5. Use the Riser Boom switch to lower the riser

boom onto the limit switch. The alarm should
stop sounding and the light should go out.

If either the Axle Unlocked Alarm or Tipover
Hazard light fails to respond correctly, repeat
this test.

If either fails a second time, remove the AB50J
from service IMMEDIATELY and refer the
problem to a qualified service technician.
