6. While observing the RCP, lights, and mast, press and hold S4 on the Base Board.
7. Ensure that the RCP and lights are properly positioned as the mast goes from 90° to the
stowed position.
8. Immediately release the S4 button as soon as the RCP shaft is in the saddle. Do not over-
drive the mast into the saddle.
9. Visually check that the mast is properly stowed. Ensure that the lights do not bounce as the
vehicle drives on the road.
6.9.4

Emergency Stow without Power

If power is lost or an unrecoverable error occurs, the mast will automatically exhaust all air and
lower to its nested height. However, the mast will not return to its fully stowed, horizontal position.
Since there is no power to run the actuator, the emergency stow button cannot be used and the
mast must be stowed manually.
To manually stow:
1. Ensure all power has been properly disconnected from the system.
2. Adjust the pan and tilt, if necessary, to place the payload in the stow position. Ensure that the
payload will not make contact with the saddle or mounting surface when the mast stows. If
your system includes lights, make sure any lights have cooled completely before manually
panning and tilting. Lights should be rotated so they will be facing down when the mast is
stowed.
3. Remove the base right side cover to access the actuator.
4. Remove the 6 mm hex head bolt on the end of the actuator cover (Figure 6-1). This bolt acts
as a cap/seal and when removed exposes the manual actuation shaft in the actuator.
5. Place a long 6 mm hex head wrench into the hole to reach another 6 mm bolt. A socket hex
head wrench may be used, but care must be taken not to damage the adjacent components.
6. Turn the hex head wrench clockwise to lower the mast. Lower the mast until it seats firmly in
the saddle.
7. Replace the right side base cover.
