Chapter 3 Maintenance
3.1 Compressor Maintenance
This compressor is oil-less with teflon rings as piston sleeves. DO NOT LUBRICATE THIS
COMPRESSOR! The piston cups are designed to run dry and the grease packed sealed bearings require
no additional lubrication. Replace compressor air filter every 6 months or sooner in dusty locations.
3.2 Valve Maintenance
The major cause of improper solenoid valve operation is foreign material lodging in the valve. It is
important to supply clean air to the valve. This is typically done with a filter regulator lubricator module
similar to Will-Burt part number 900484. The filter bowl should be drained regularly. The lubricator should
be adjusted to put a fine mist into the air line in direct proportion to the rate of flow.
