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 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, 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. Operate the mast to the desired position for the maintenance procedure.
2. Active the emergency stop if the location is not in the nested position to turn off the mast.
Note the mast will descend if extended as air will be removed from the mast.
3. 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 pro-
hibit unexpected power up.
4. Unplug the mast hand held remote control and keep it with the maintenance engineer during
maintenance to avoid unexpected mast operation.
Refer to section 6.4 for power-up procedure once maintenance is complete.
7.2

Cleaning and Lubricating the System

Will-Burt 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 might 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
To clean the system:
1. While at 90°, wipe down the base using a soft cloth or sponge and a mild solution of soapy
water.
2. Wipe down the RCP using a soft cloth or sponge and a mild solution of soapy water.
