MAINTENANCE

WARNINg! do not make any repairs, adjustments, or maintenance on the air compressor 

unless it is disconnected from the electrical power and the tank pressure is released.
Maintenance should always be performed by a qualified technician.

1. 

Check the oil level before each use. If the oil is low, add some. If it is high, drain some 

by removing the Drain Plug. Replace the oil once a year.

2.  Check and clean the Air Filter (B-5) every 50 hours, or sooner if used in a dusty 

environment.

3.  Drain the air tanks after each use by opening the drain petcock or the Tank Drain 

Valve (A-7). Leave open until the next use.

4.  After the compressor has cooled down, clean it with a damp rag containing mild 

detergent and water. Do not use flammable liquids or solvents.
