7.8.2 Adjusting the mast 90° Limit Switch
The 90° Switch (Figure 7-2 and Figure 7-3) senses when the mast is at 90° by checking the
position of the actuator. There is a magnet mounted to the actuator arm that triggers the limit
switch. When the mast is being raised from the stowed position and the 90° Switch is sensed,
power to the actuator is removed. This allows the mast to remain at 90°. The mast will not extend
and certain remote control functions will not function if the mast is not at 90°.
To adjust the 90° Limit Switch:
1. Make certain that the base is level.
2. Remove the left base cover to access the Limit Switches and Base Board.
3. Loosen the lock nuts to adjust the switch position in the slot.
4. Raise the mast to 90° by holding the "Mast Up" button until the mast is at 90°. Do not use the
Auto-Up feature to raise the mast to 90°.
5. Check that the mast is at 90° by using a level, ensuring that the mast is square to the sheet
metal side plate on the base. A value range of 89.5 to 90.5° is acceptable.
6. Adjust the 90° Switch until it senses the actuator. This is indicated by the diagnostic LEDs on
the Base Board (Figure 7-1).
7. Secure the switch in position using the lock nuts.
8. Raise and lower the mast several times, checking that the mast is plumb each time, and
adjust the switch if necessary. The mast should drive into the rubber pad slightly for stability.
