6.10.3 Emergency Stow with Power
If the mast cannot be stowed using the Auto Stow® feature or "Mast Down" button, the
emergency stow button (S4) on the Base Board can be used to stow the mast if the following are
both true:
• Power is still applied to the system.
• The actuator is still functional.
Using the emergency stow button causes the actuator to lower the mast without regard to any
faults, switches, or system interlocks. It is totally up to the operator to ensure safe operation
during an emergency stow attempt. Also, the current limiting feature is not used so it is possible
to over-drive the actuator. Release the S4 button once the saddle is reached. Pressing the
emergency stow button causes the system to generate an "ERR 1,20" error. Errors cause the
mast to automatically:
• Move the mast to the home position (provided there are no electrical or mechanical issues).
• Exhaust all air from the mast, which lowers the mast to its nested position.
Once the mast has lowered to its nested position, pressing and holding S4 will drive the tilt
actuator to stow the mast. The mast will continue to tilt and drive in the saddle until S4 is
released. Do not over-drive the actuator into the saddle.
To stow the mast using the emergency stow button:
1. Remove the left side cover (the side with the look-up light) (as viewed from the back of the
mast).
2. Tap S4 on the Base Board. Do not hold down S4; just press, then immediately release S4
once. This will cause the controller to show an "ERR 1,20". The error will cause the mast to
go to its home position and exhaust all air from the mast.
3. Wait until all air has exhausted from the mast. The mast should now be retracted and in the
90° position.
4. Ensure there are no obstructions in the path of the mast.
5. While observing the mast, press and hold S4 on the Base Board.
6. Ensure that the mast is properly positioned as it goes from 90° to the stowed position.
7. Immediately release the S4 button as soon as the mast is in the saddle. Do not over-drive the
mast into the saddle.
8. Visually check that the mast is properly stowed. Ensure that the mast does not bounce as the
vehicle drives on the road.
