3.6.2 Detailed Instructions
The following are detailed instructions describing the operation of the Mast System using the
Crank Handle Assembly.
Use manual operation for emergency situations only. The normal limit switches and software
limits are not in effect during manual operation. There are mechanical hard stops just beyond
both the upper and lower limit switch locations that will stop the mast safety, however it is good
practice to stop the mast at the normal positions.
Note: When manually operating the mast, the intermediate height on the Universal Control Box
will not change.
Prepare the System for Manual Operation
To prepare the Mast System for manual operation:
•
Ensure the Mast System is stationary on level, stable ground
•
Perform the Pre-Operation Check (Section 3.1)
•
Ensure power is removed from the Mast System. Do not manually operate the Mast
System with power to the Mast System.
•
Retrieve the Crank Handle Assembly from its storage location.
The Mast System is now operational.
