8. POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES
FAULT
Leakage of air from the valve
of the pressure switch with the
compressor off.
Reduction of performance.
Frequent start-up. Low pressure
values.
The compressor stops and
restarts automatically after a few
minutes.
In the V, 3 HP versions, it is does
not start.
After a few attempts to restart,
the compressor.
The compressor does not stop
and the safety valve is tripped.
Any other type of operation must be carried out by authorized Service Centers, requesting original
parts. Tampering with the machine may impair its safety and in any case make the warranty null
and void.

area. Reset the thermal cutout.
On lubricated and V type
models, check oil level and
quality. On V models, have the
voltage checked.
Activate the on/off switch.
