MAINTENANCE AND CLEANING

Disconnect AIR COMPRESSOR from power source and
bleed off all air pressure before attempting any maintenance or repair.
WHEN PERFORMING ANY MAINTENANCE OR SERVICE:
• The air compressor must be turned off.
• Disconnect compressor from the power source.
• Open tank drain to bleed off all air pressure before attempting any maintenance
or repair.
• Allow compressor to fully cool before attempting any maintenance or repair.
Check the air compressor frequently for any visible problems and follow mainte-
nance procedures each time the compressor is used.
All air compressors contain maintenance parts that require
periodic replacement. These used parts, including air filters and used lubricat-
ing oil, may contain regulated substances that must be disposed of in accor-
dance with local, state, and federal laws and regulations.
1. Slowly open tank drain valve to release pressure from the system and drain
moisture from the air tank. Tilt tank to remove all moisture. Once all the mois-
ture has drained out, close tank drain valve securely.
2. Wipe the compressor clean.
MAINTENANCE CHECKLIST:
Daily:
• Check oil level.
• Drain accumulated liquid from tank.
• Check for oil leaks.
• Check for unusual noise
and/or vibrations.
• Check that all fasteners are secure.
• Wipe compressor clean.
+ 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.
SIX MONTHS OR 200 OPERATING HOURS:
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.
Weekly:
• Inspect and clean air filter.
• Clean breather holes on oil fill plug.
Monthly:
• Check for air leaks. +
• Check safety relief valve.

OIL CHANGE:
• Change compressor oil. Use only SAE 30 weight non-detergent air compressor oil.
• Replace oil more frequently when used in dusty operating environments.
• 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.
2. Allow compressor to fully cool before attempting any maintenance or repair.
3. To access the oil drain plug, plastic front cover needs to be removed. Using
5/32 in. hex wrench, remove the 2 hex head screws and remove the front panel.
4. Place a suitable oil drain pan below oil
drain plug (see Figure 10).
5. Remove oil fill breather plug to allow air
to enter crankcase.
6. Remove oil drain plug.
7. Allow oil to drain completely. Tilt air
compressor towards the oil drain to
assist draining.
8. Clean and replace oil drain plug.
9. Refill crankcase with SAE 30 weight
non-detergent air compressor oil until
the oil level reaches the center of the red
circle in the oil level sight glass. Be careful not to overfill.
10.Reinstall the oil fill breather plug and plastic front cover.
NOTE: Used oil should be recycled or properly disposed of. Consult your local liq-
uid/solid waste authority for information on proper recycling or disposal.
CHECKING SAFETY RELIEF VALVE:
Safety RELIEF 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 relief valve.
