Troubleshooting

 

 

Troubleshooting problems may have similar causes and solutions.

 

 
 

 

 

 

Low pressure, not enough air, or compressor does not stop.

 

o

 

Tank drain valve is open: Close drain valve.

 

 

 

Prolonged excessive air.

 

o

 

Decrease amount of air used.

 

 

 

Compressor not large enough for job.

 

o

 

Check air requirement of accessory. If it is higher than CFM and pressure of compressor, you need a larger compressor. Most 
accessories are rated at 25% of actual CFM while running continuously.

 

 

 

Restricted check valve.

 

o

 

Remove and clean or replace.

 

 

 

Hole in air hose.

 

o

 

Check and replace if necessary.

 

 

 

Tank leaks.

 

o

 

Replace tank.

 

 

Immediately replace tank. Do not attempt to repair.

 

 
 

 

 

Blown seals.

 

o

 

Replace any faulty seals.

 

o

 

Replace worn parts and reassemble with new seals.

 

 

 

Excessive starting and stopping while not in use.

 

o

 

Fittings leak. Check fittings with soapy water. Tighten or reseal leaking fittings. DO NOT OVERTIGHTEN.

 

o

 

Replace worn parts and reassemble with new seals.

 

o

 

Replace any regulator internal parts.

 

 

 

Regulated pressure gauge reading drops when air accessory is being used.

 

o

 

This is normal in some applications.

 

 

 

Compressor not large enough.

 

o

 

If pressure drops too low, adjust regulator while accessory is used.

 

o

 

Check air requirement of accessory, it may be higher than CFM pressure supplied by compressor. Most accessories are rated 
at 25% of actual CFM while running continuously.

 

 

 

Circuit breaker trips (fuse blows) too often.

 

o

 

Low voltage, consult electrician.
