air filter.
1. Check valve components are dirty/damaged.
2. Reed valve(s) not sealing.
1. Clean/replace check valve components (
Page 30).
2. Remove cylinder head and replace reed valve(s).
Air tools have
oily discharge.
1. Tank needs to be drained.
2. In-line oiler is out of adjustment (if used).
3. In-line filter is damaged or missing (if used).
4. Compressor pump is at fault.
1. Open drain valve to drain condensation.
2. Adjust in-line oiler drip ratio or use correct viscosity oil.
3. Replace filter or in-line filter assembly.
4. Worn compressor piston, rings, or valves. Rebuild or
replace pump.
Air tools
have watery
discharge or
get cold and
freeze up with
ice during use.
1. Tank needs to be drained.
2. In-line water separator is full (if used).
3. Ambient environment has too much humidity.
1. Open drain valve to drain condensation.
2. Drain water separator.
3. Install in-line air dryer and water separator.
Air tool has low
supply pressure
but compressor
has sufficient
air pressure.
1. Air hose is too long.
2. Regulator needs to be adjusted for higher
airflow delivery.
3. Machine is undersized.
4. In-line filter is damaged or clogged (if used).
5. In-line water separator is full (if used).
6. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
7. Air leaks in hose.
8. Regulator at fault.
9. Pressure gauge(s) at fault.
1. Use shorter hose.
2. Turn regulator knob clockwise to increase line PSI. DO
NOT exceed pressure rating of attached tool.
3. Use a smaller attachment tool or a larger air
compressor.
4. Replace filter or in-line filter assembly.
5. Drain water separator.
6. Adjust settings (
Page 31). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
7. Check air hoses and all connections for leaks
(
Page 26).
8. Inspect regulator for leaks. Replace if at fault.
9. Replace pressure gauge(s).
Safety relief
valve leaks.
1. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
2. Safety relief valve at fault.
3. Pressure switch at fault.
1. Adjust settings (
Page 31). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
2. Test/replace.
3. Turn compressor
OFF, disconnect from power, and
empty tank. DO NOT USE until switch is replaced.
Delivered air
is dirty or has
excessive
moisture.
1. Tank needs to be drained.
2. Delivery pipes are dirty (if used).
