TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
REMEDY
Compressor will not run.
Reduction of performance.
Frequent start-up. Low
pressure values.
The compressor starts,
pressure is shown on the
pressure gauge, but the
tools do not start.
The compressor keeps
cutting out.
Pressure drop in the tank.
Pressure switch valve
leaks when compressor is
idle.
Compressor stops and
does not restart.
Compressor does not stop
at max pressure.
Compressor does not
reach max pressure.
Compressor noisy with
metallic knock.
No electrical power.
Blown fuse.
Breaker open.
Pressure switch bad.
Excessive performance request,
check for any leaks from the
couplings and/or pipes. Intake
filter may be clogged.
Loose hose connections.
Leak in a quick release connector.
Insufficient pressure set on the
pressure regulator.
Tripping of the thermal cutout due
to overheating of the motor
(removal of the plug with the
compressor running, low power
voltage).
Air leaks at connections.
Air leaks from safety valve.
Air leaks from cylinder head
gasket.
Non-return valve seal defective.
Power failure. Motor failure.
Pressure switch fault.
Filter clogged.
Head gasket or valve fault.
Low oil level.
Bearing or piston damage.
Check unit is plugged in.
Check fuse/breaker.
Replace blown fuse.
Reset, determine cause of problem.
Take compressor to service center.
Clean the air ducts. Ventilate the work
area.
Check the compressed air hose and
tools and replace if necessary.
Check the quick release connector and
replace if necessary.
Open the pressure regulator further.
Activate the on/off switch. Ventilate the
work area. Wait a few minutes. The
compressor will restart independently.
Remove any power cable extensions.
Run compressor to max. pressure,
then switch off. Brush soap solution
over connections and look for bubbles.
Tighten connections showing leaks.
If problem persists contact Authorised
Service Agent.
Operate the safety valve manually by
pulling on the ring. If valve continues to
leak when in the closed position it
should be replaced.
Check tightness of head bolts. If leak
continues contact Authorised service
Agent.
Replace pressure switch.
Check electricity supply and fuse.
