TROUBLESHOOTING
PROBLEM
There is low
pressure, not
enough air, or the
compressor does
not stop.
Air leaks from the
regulator or the
regulator does
not regulate air
pressure.
The regulated
pressure gauge
reading drops when
the air accessory is
being used.
The pressure relief
valve opens.

POSSIBLE CAUSE
1. The tank drain valve is open.
2. There is a leak in the fittings.
3. There is a prolonged or
excessive use or air.
4. The compressor is not large
enough.
5. There is a hole in the air hose.
6. The tank leaks.
7. The seals are blown.
8. The valve leaks.
9. There is a leaking or worn
piston.
1. The internal parts of the
regulator are dirty or damaged.
1. This is normal.
2. The compressor is not large
enough.
1. The tank pressure exceeds the
normal rating pressure.
2. The pressure switch is stuck.
CORRECTIVE ACTION
1. Close the tank and drain the valve.
2. Check fittings with soapy water.
Tighten or reseal leaking fittings.
DO NOT OVERTIGHTEN.
3. Decrease the amount of air used.
4. Check the air requirement or the
accessory. If it is higher than the
CFM and the pressure supplied by
the compressor, you need a larger
compressor. Most accessories are
rated at 25% of the actual CFM
while running continuously.
5. Check and replace if necessary.
6.
replace the tank. DO NOT attempt
to repair.
7. Replace the compressor assembly.
8. Replace the compressor assembly.
9. Replace the compressor assembly.
1. Replace the regulator or internal
parts.
1. If the pressure drops too low,
adjust the regulator while the
accessory is used.
2. Check the air requirement or the
accessory. If it is higher than the
CFM and the pressure supplied by
the compressor, you need a larger
compressor. Most accessories are
rated at 25% of the actual CFM
while running continuously.
1. Replace the pressure switch.
2. Replace the pressure switch.
