Symptom Possible Cause Possible Solution
Machine has
vibration or
noisy operation. 1. Motor or component loose.
2. Machine feet loose.
3. Motor fan rubbing on fan cover.
4. Motor bearings at fault.
5. Compressor pump at fault.
1. Replace damaged or missing bolts/nuts or tighten if
loose.
2. Tighten screws.
3. Fix/replace fan cover; replace loose/damaged fan.
4. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
5. Compressor piston rod/bearings/crankshaft is worn.
Rebuild or replace pump.
Motor runs
continuously. 1. Machine is undersized.
2. Regulator needs to be adjusted for lower
airflow delivery.
3. Air leak in tanks 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 tanks, 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 tanks. 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 tanks.
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

6. Check valve components are dirty/damaged.
7. Pressure relief valve releasing below 135
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 tanks, 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.
