Troubleshooting
Warning.
Before attempting any maintenance on the compressor;
• disconnect the mains electrical supply
• release the pressure in the air tank
• maintenance should be performed only by personnel suitably trained in the operation of
the compressor
Compressor does not start
1) No power from mains. Check fuses and socket.
2) Faulty electrical connections. Check continuity.
3) Oil level too high. Drain oil and replenish to correct level.
4) Excessive pressure in air tank. Operate the pressure relief valve to exhaust the
tank pressure.
5) Leaking non-return valve. Check for air leaking from the valve. Unscrew the valve
cap and remove the rubber seal. Clean the rubber seal and its seat with a dry
cloth. Refit the seal and the valve cap. If leakage persists replace the valve.
6) Faulty starter relay. Contact the service agency.
7) Faulty condenser. Replace the condenser or contact the service agency.
8) Thermal overload switch active. Wait for compressor to cool and ensure adequate
ventilation.
Compressor runs but pressure increases too slowly
1) The transportation cap has not been removed from the air intake pipe.
2) Air filter clogged. Clean or replace the filter.
3) Air leaks. Can be due to a bad seal/connection of any pipe. Check all pipe
connections.
Compressor does not reach maximum pressure
1) Air leaks. Can be due to a bad seal/connection of any pipe. Check all pipe
connections.
2) A failure in the non-return valve is creating a flow restriction. Replace the valve.
Compressor stops after working normally
1) The motor incorporates automatic thermal protection which stops the compressor
when the oil temperature is too high. The compressor can be restarted after
approx 50 minutes.
