Troubleshooting

Possible Solution
1. Motor will not start if tanks are fully pressurized.
2. Ensure correct power supply voltage and circuit size
(Page 11).
3. Adjust settings (Page 34). Do not exceed cut-in/cut-
out pressures listed on data sheet (Page 6) or inside
pressure switch.
4. Ensure circuit is free of shorts. Reset circuit breaker or
replace fuse.
5. Reduce load on compressor and allow longer cool
down periods. Press motor overload reset button to
reset when motor has cooled (Page 5).
6. Test/replace if at fault.
7. Adjust centrifugal switch/clean contact points. Replace
either if at fault.
8. Fix broken wires or disconnected/corroded
connections.
9. Clean/replace check valve components (Page 33).
10. Turn compressor OFF, disconnect from power, and
empty tanks. DO NOT USE until switch is replaced.
11. Replace motor.
1. Replace air filter (Page 26).
2. Clean cylinder fins, motor fan, and vent area.
3. Adjust settings (Page 34). Do not exceed cut-in/cut-
out pressures listed on data sheet (Page 6) or inside
pressure switch.
4. Reduce load on compressor and allow longer cool
down periods. Press motor overload reset button to
reset when motor has cooled (Page 5).
5. Drain and replace with correct oil (Page 25).
6. Test/repair/replace.
7. Move machine closer to power supply; use shorter
extension cord.
8. Clean/replace check valve components (Page 33).
9. Adjust centrifugal switch/clean contact points. Replace
either if at fault.
10. Replace motor.
11. Rebuild/replace.
