Operation
Symptom
Possible Cause
Possible Solution
Air leaks from
pressure
switch.
1. Check valve components are dirty/damaged.
2. Pressure switch at fault.
1. Clean/replace check valve components (
Page 30).
2. Turn compressor
OFF, disconnect from power, and
empty tank. DO NOT USE until switch is replaced.
Low pressure
in tank, or
tank pressure
drops after
compressor is
turned
OFF.
1. Drain valve is open.
2. Air filter dirty/clogged.
3. Regulator needs to be adjusted for lower
airflow delivery.
4. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
5. Air leak in tank or delivery pipes.
6. Check valve components are dirty/damaged.
7. Pressure relief valve releasing below 115
PSI.
8. Gasket(s) leaking.
9. Worn pump piston rings.
1. Close drain valve.
2. Replace air filter (
Page 24).
3. Turn regulator knob counterclockwise to decrease line
PSI.
4. Adjust settings (
Page 31). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
5. Check air tank, pipes, and all connections for leaks
(
Page 26). Do not attempt to repair leaking/damaged
tank, only replace.
6. Clean/replace check valve components (
Page 30).
7. Replace pressure relief valve.
8. Check gaskets on cylinder head assemblies, repair or
replace as needed.
9. Inspect and replace pump piston rings.
Compressor
does not build
air pressure, or
does not reach
full pressure.
1. Drain valve is open.
2. Tank needs to be drained.
3. Air filter dirty/clogged.
4. Air leak in tank or delivery pipes.
5. Check valve components are dirty/damaged.
6. Reed valve(s) not sealing.
7. Head gasket or valve body gasket leaking.
8. Worn pump piston rings.
9. Broken crankshaft or connecting rod.
1. Close drain valve.
2. Open drain valve to drain condensation, then close.
3. Replace air filter (
Page 24).
4. Check air tank, pipes, and all connections for leaks
(
Page 26). Do not attempt to repair leaking/damaged
tank, only replace.
5. Clean/replace check valve components (
Page 30).
6. Remove cylinder head and replace reed valve(s).
7. Remove cylinder head and replace gasket(s).
8. Inspect and replace pump piston rings.
9. Replace or rebuild compressor pump.
Symptom
Possible Cause
Possible Solution
Motor runs
continuously.
1. Machine is undersized.
2. Regulator needs to be adjusted for lower
airflow delivery.
3. Air leak in tank or delivery pipes.
4. Pressure switch at fault.
1. Use a smaller attachment tool or a larger air
compressor.
2. Turn regulator knob counterclockwise to decrease line
PSI.
3. Check air tank, pipes, and all connections for leaks
(
Page 26). Do not attempt to repair leaking/damaged
tank, only replace.
4. Turn compressor
OFF, disconnect from power, and
empty tank. DO NOT USE until switch is replaced.
Pressure relief
valve stays
open and motor
will not stop
running.
1. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
2. Pressure switch at fault, unit is trying to
overpressurize tank.
3. Pressure relief valve at fault/relieving
pressure too early.
1. Adjust settings (
Page 31). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
2. Turn compressor
OFF, disconnect from power, and
empty tank. DO NOT USE until switch is replaced.
3. Replace.
