13 TROUBLESHOOTING
Problem Cause Resolution
Stop machine for
oil thermostat
intervention Excessive temperature of air/oil
mixture exiting the screw
(max 105°C)
- Check the oil level
- Check the clean of cooler.
- Check when the machine is running if the fan
works
To restart the machine must be switched off
and press the reset thermostat button located
under the cover of the thermostat.
If the arrest due to high temperature persists,
contact the service center.
Stop machine
intervention thermal
compressor motor
- Switch 0/1 on the pressure
switch unarmed and
compressor is stopped.
- High temperature of motor.
- High power consumption.
- If the intervention happens when the
compressor is on, check that the phases are
stable.
- If it happens when the compressor is
running, make sure the internal pressure of
the group and replace the separator
cartridge.
- If the motor draws a current higher than the
rated current, contact an authorized service
technician.
Do not insist too much with the starts
because they could cause serious damage
to the electrical plant of compressor
Opening safety
valve
Pressure switch do
esn’t work and
the pressure exceeds the value
set by the safety valve.

switch has traces of oxide or dirt. If there
are, remove them with a mild antioxidant
- Intake valve does not close, check that it is
locked.
The compressor runs
but the pressure
remains low
- The intake valve does not
open
- Loss of air that prevents the
increase pressure
- Coupling screw-engine to check
- When the machine is off and depressurized
safely, remove the air filter and check if the
shutter moves
- Check if there are leaks from the pipes that
disperse the air produced.
