CAUSE
of the switch.
SOLUTIONS
1. Double-check feeding line voltage, the fuses or correct
the motor overload.
2. Consult with a quali ed electrician.
3. Inspect to detect leaks. If replacing the valve is
necessary go to a TASC*.
1. Double-check feeding line voltage, the fuses or correct
the motor overload.
2. Consult with a quali ed electrician.
1. Change and use SAE-30 oil
2. Add oil to the casing up to the right level.
3. A more effective lter is needed in the air admission. Go
to the nearest TASC*
1. Double-check feeding line voltage, the fuses or correct
the motor overload.
2. Consult with a quali ed electrician.
3. Ask for a motor capacitor check-up (only monophasic
units) in a TASC*
4. Double-check if the tank pressure is higher than the
cutting pressure in the pressure switch (the motor will
start again when pressure in the tank drops below the
cutting pressure).
5. Check to detect leaks. If replacing the valve is needed
go to a TASC*
6. Press the thermic button to restart the motor.
