PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
There is low
pressure, not
enough air, or the
compressor does
not stop.
1. The drain valve is open.
3. There is a prolonged or excessive
use of 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. Close the drain valve.
DO NOT OVERTIGHTEN.
3. Decrease the amount of air used.
4. Check the air requirement of 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.
WARNING: Immediately
replace the tank. DO NOT attempt
to repair.
7. Replace the compressor assembly.
8. Replace the compressor assembly.
9. Replace the compressor assembly.
Air leaks from the
regulator or the
regulator does
not regulate air
pressure.
1. The internal parts of the regulator
are dirty or damaged.
1. Replace the regulator or internal
parts.
The regulated
pressure gauge
reading drops
when the air
accessory is being
used.
1. This is normal.
2. The compressor is not large enough.
1. If the pressure drops too low,
adjust the regulator while the
accessory is used.
2. Check the air requirement of 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.
The pressure relief
valve opens.
1. The tank pressure exceeds the
normal rating pressure.
2. The pressure switch is stuck.
1. Replace the pressure switch.
2. Replace the pressure switch.
