Troubleshooting,
Malfunctions
Inadequate compressor
delivery performance
Air leaks from the pressure
vessel into the air line:
"Hiss" in the compressed air
supply line when switching
off the compressor
Compressor switches off
during operation,
overheating of the motor
Compressor stops during
operation
Compressor vibrates during
operation, uneven hum of
the motor, motor hums after
rebooting, the compressor
will not start.
Residual oil in the
compressed air and the
pressure vessel
NOTE: If malfunctions are not listed here, contact the manufacturer, authorised on-site
representative or retailer.
Probable cause
A dirty air filter
Bad connection or damaged air
lines
Belt slippage due to low voltage
or dirt
Check valve wear or foreign
body between the valve and
seat
Low oil level in the crankcase
of the compressor
Continuous operation of the
compressor with a relative duty
cycle [ED] of over 60%, max.
pressure and air consumption.
Motor protection is activated
Power supply circuit failure
No voltage in one phase of the
power supply circuit
Oil level in crankcase too high

Solution
Clean or replace filter element
Locate air leakage, tighten the
screws, replace air line
Tighten the belt and remove dirt
Loosen hex bolt, clean seat and
valve
Check the oil quality and status,
replenish as required
Reduce compressor load by
reducing air consumption, restart
motor
Check the power supply circuit
Check the power supply circuit
Restore normal oil level
