TROUBLESHOOTING
Risk of electric shock.
Before interfering with the equipment, first disconnect it from the mains (remove
the power socket).
Working with pressurised pneumatic components poses a risk of injury.
Before interfering with the equipment, vent the air tank and the compressed air
system to zero pressure.
Troubleshooting may only be performed by a qualified service technician.
Damage to the safety valve could cause pressure to rise to hazardous levels.
Never adjust a safety valve.
Malfunction Possible cause Solution
Compressor does
not switch on No voltage in the pressure switch
Check voltage in socket
Check circuit breaker switch
–
switch to position switched-
on „I“
Loose conductor from terminal -
repair
Check electrical cord
– replace
defective cord
Motor winding failure, damaged
thermal protection Replace motor or windings
Capacitor failure Replace capacitor
Seized piston or other rotating part Replace damaged components
Pressure switch does not switch Check function of pressure switch
Compressor often
switches on Air leakage in pneumatic system Check pneumatic system
– seal
loose connections
Non-return valve (SV) leakage Clean non-return valve, replace
seals, replace non-return valve
Large volume of condensed liquid in
pressure tank Drain condensed liquid
Low compressor capacity Check time of filling the air tank
Low pressure in
the air tank
(compressor
running constantly) High air consumption of supplied
equipment Decrease air consumption
Use compressor with higher
capacity
Leakage in pneumatic system Check pneumatic system
– seal
loose connections
Low capacity of the pump Clean / replace the pump
Pump failure Clean / replace the pump
Dryer failure Replace dryer
Prolonged
operation of the Air leakage in pneumatic system Check pneumatic system
– seal
loose connection
