Mast Cleaning and Lubrication

The Will-Burt Company's Pneumatic Masts come from the factory pre-lubricated. Under normal
operating conditions, the grease applied at the factory is sufficient for five years and no
scheduled maintenance is required. In extremely harsh environmental conditions, maintenance
of the mast may be required.
An optional mast lubricant (P/N: 900600) may be added to ensure smooth operation and prolong
the useful life of the mast in harsh environmental conditions. The mast lubricant is a blue-colored
mineral oil specifically designed for telescoping masts and their operating environment. Mast
lubricant comes in a 16 oz. capped plastic bottle.
The Will-Burt Company recommends removing the payload before performing the mast cleaning
and lubrication process.
Signs cleaning and lubrication might be needed can be:
• A noticeable gritty film on the exterior surfaces of the tubes
• Erratic extension or retraction of the mast
• Noisy operation of the mast
• Sticking of one or more tubes when mast is extending or retracting
