Instruction manual for owner's use
7. POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES
Request the assistance of a qualified electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc).
Fault
Air leak from the valve of the pressure switch.
Reduction of efficiency, frequent start-up. Low
pressure values
The motor and/or the compressor overheat
irregularly.
After an attempt to start the compressor, it Stops
due to tripping of the thermal cutout caused by
orcing of the motor.
During operation, the compressor stops for no
apparent reason.
When operating, the compressor vibrates and
the motor emits an irregular buzzing sound. If if
stops, it does not restart although the sound of
the motor is present.
Irregular presence of oil in the network.
Leaking of condensate from the vent cock.
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.
Cause
Check valve does not perform its function
correctly due to wear or dirt on the seal.
Condensate drainage cock open (11).
Rilsan hose not inserted correctly in pressure
switch.
Excessively high consumption.
Leaks from joints and/or pipes.
Clogging of the suction filter (18).
Slipping of the belt
Insufficient ventilation.
Closing of air ducts.
Insufficient lubrication.
Start-up with head of the compressor charged.
Low temperature.
Voltage too low.
Incorrect or insufficient lubrication
Inefficient electrovalve.
Tripping of the thermal cutout of the motor
Electric Fault
Faulty capacitor.
Too much oil inside the unit.
Wear on segments.
Presence of dirt/grit inside the cock.
Remedy
Unscrew the hex-shaped head of the check
valve, clean the housing and the special rubber
disk (replace if wom). Re-assembler and tighten
carefully
Close the Condensate drainage cock (11).
Insert the Rilsan hose correctly inside the
pressure switch
Decrease the demand of compressed air.
Change gaskets
Clean/replace the suction filter (18) (fig. 5a-5f).
Check belt tension
Improve ambient conditions.
Check and if necessary clean the air filter.
Top up or change oil (fig. 8a-9d).
Relase the compressor head by using the pressure
switch push button.
Improve ambient conditions.
Check that the mains voltage matches that of the
dataplace. Eliminate any extensions
Check level, top up and if necessary change the oil.
Call the Service Center
Check level oil
Operate on the button (8) of the pressure switch (1)
returning this to the OFF position
Reset the thermal cutout (19) (fig.6) and restart
If the fault persists, call the Service Center.
Call the service center.
Have the capacitor replaced.
Check oil level.
Call the Service Center.
Clean the cock.
