Six months or 200 operating hours*:
Change compressor oil. Use only SAE 30 weight non-detergent air compressor oil.
Replace oil more frequently when used in dusty operating environments.
* The pump oil must be changed after the first 20 hours of operation. Thereafter, change oil every 200 hours of operation or every six
months, whichever comes first. In harsh operating conditions, maintenance must be performed more frequently.
+ Apply a solution of soapy water around joints. Look for air bubbles around joints when compressor reaches the pressure cut-out limit
and the pump turns off.
Oil change:
Used lubricating oil, may contain regulated substances that must be disposed of in accordance with local, state, and federal laws and
regulations.
1. The air compressor must be turned OFF.

3. Place a suitable oil drain pan below oil drain plug.
4. Remove oil fill plug to allow air to enter crankcase.
5. Remove oil drain plug.
4. Allow oil to drain completely. Tilt air compressor towards the oil drain to assist draining.
5. Clean and replace oil drain plug.
6. Refill crankcase with SAE 30 weight non-detergent air compressor oil until the oil level reaches the top of the red circle in the oil
level sight glass. Be careful not to overfill.
7. Reinstall the oil fill plug.
Checking Safety Relief Valve:
SAFETY VALVE MUST BE REPLACED IF IT CANNOT BE ACTUATED OR IT LEAKS AIR AFTER THE RING IS RELEASED.
1. The air compressor must be turned OFF.
2. Disconnect compressor from the power source.
3. Open tank drain to bleed off all air pressure before attempting any maintenance or repair.
4. Allow compressor to fully cool before attempting any maintenance or repair.
5. Grasp the wire ring on the safety valve.
6. Pull and release the ring a few times to ensure that the plunger moves in and out. Replace the safety valve if plunger does not
move or is difficult to move.
Checking Air Filter Element:
1. The air compressor must be turned OFF.
2. Disconnect compressor from the power source.
3. Open tank drain to bleed off all air pressure before attempting any maintenance or repair.
4. Allow compressor to fully cool before attempting any maintenance or repair.
