Routine Maintenance
You must follow the maintenance schedule and use only Airworks genuine replacement parts to maintain
your system and warranty.
The most critical aspect of maintenance is proper air filtration and clean oil. If any particles enter the
compressor through the air inlet or other means, they can contaminate roller bearings, gears and rotors in
the compressor. Contamination will cause severe and rapid damage to components.
Ensure compressor is completely unloaded before servicing. Clean Areas to be serviced. Remove fill
cap and filters slowly.
Damage caused by contamination not covered by warranty.
