TROUBLESHOOTING
 Entrust a specialised company to sort and dispose of waste.
 Worn out components have no negative environmental impact.
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
Compressor does
not switch on
Compressor often
switches on
Low pressure in
the air tank
(compressor
running constantly)
05/2022
Possible cause
No voltage in the pressure switch
Motor winding failure, damaged
thermal protection
Capacitor failure
Seized piston or other rotating part
Pressure switch does not switch
Air leakage in pneumatic system
Non-return valve (SV) leakage
Large volume of condensed liquid in
pressure tank
Low compressor capacity
High air consumption of supplied
equipment
Leakage in pneumatic system
Low capacity of the pump
Pump failure
Solution
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
Replace motor or windings
Replace capacitor
Replace damaged components
Check function of pressure switch
Check pneumatic system – seal
loose connections
Clean non-return valve, replace
seals, replace non-return valve
Drain condensed liquid
Check time of filling the air tank
Decrease air consumption
Use compressor with higher
capacity
Check pneumatic system – seal
loose connections
Clean / replace the pump
Clean / replace the pump
