8.0 POSSIBILIBIES OF FAILURE
1 When pushing the pressure switch the compressor does not run:
* blown fuse
* tank at pressure
* motor broken
* thermal failure
* defective pressure switch
- blown control current fuse
- defective star-delta switch
2 Repeating thermal failure:
* blown fuse
* loose wire
* pressure switch does not relieve
air circuit
* too low voltage
- defective electric valve
* overloading
3 Compressor keeps blowing off air:
* defective non-return valve
4 Too little air production:

5 Leaking safety valve:
* pressure too high
* defective safety valve
* general failures

Note:
to obtain conditioned dry air it is recommended to use a compressed air dryer in
combination with a pressure reducing valve for a constant operating pressure. Ask
your dealer for more information.
