7.5.3 Adjusting the Mast Stowed Limit Switch
The Mast Stowed (near 0°) Switch (Figure 7-2) senses that the mast is in the saddle upon power
up, and when the mast is nearing the saddle during stowing. The circuit then looks for a pre-
determined current rise (for a maximum of 0.5 seconds) to indicate a solid nesting before shut -
ting off. This current monitoring allows the controls to drive the RCP into the saddle to remove all
mechanical play for vehicle transport. The limit switch is activated by a magnet located on the
actuator arm.
To adjust the Mast Stowed Switch:
1. Make certain that the base is level.
2. Remove the two base covers to access the switches and Base Board.
3. Raise the mast to gain access to the Mast Stowed Switch.
4. Loosen the lock nuts to adjust the switch position in the slot.
