7 Maintenance, Adjustments and Disposal
This section describes the routine maintenance and adjustment procedures required to keep
your system operational. Be sure to read and understand the entire operation procedure (Section
6) and the Safety Summary (Section 1) before beginning any maintenance or adjustment
procedure.
7.1 Power Isolating Procedure
Remove all power sources from the mast system (including mast controls, lighting power, and
auxiliary device power) before performing any maintenance operation on the mast system other
than optional cleaning and lubricating. Use proper lock-out tag-out procedures.
To isolate power to the mast system:
1. Disconnect all power sources using lock-out tag-out procedures. It is recommended that the
vehicle ignition keys be held by the maintenance engineer as an additional precaution to
prohibit unexpected power-up.
2. Unplug the mast Hand-Held Remote Control (HHRC) and keep it with the maintenance
engineer during maintenance to avoid unexpected mast operation. Be sure the HHRC is
attached before powering up the system again to avoid a communications error.
Refer to section 6.4 for power-up procedure once maintenance is complete.
7.2 Cleaning and Lubricating the System
The Will-Burt Company’s pneumatic telescoping masts come from the factory pre-lubricated and
require no scheduled lubrication under normal operating conditions for the life of the product. In
extremely harsh environmental conditions, cleaning and lubrication of the mast may be required.
Signs that cleaning and lubrication are needed can be:
• A noticeable gritty film on the exterior surfaces of the mast sections.
• Erratic extension or retraction of the mast.
• Noisy operation of the mast.
• Sticking of one or more mast sections when mast is extending or retracting.
