Fault Possible cause Remedy
Machine runs hot. Ambient temperature too high. Reduce the ambient tempera‐
ture.
Wrong direction of rotation. Changeover phase lines L1 and
L2.
Fan cannot draw air freely. Ensure unrestricted flow of air
to the fan.
Valves
1)
or valve plate between
cylinder head and cylinder are
leaking or dirty.
Have the valve
1)
or valve plate
replaced by a
KAESER SERVICE technician.
Broken pressure valve reed. Call KAESER SERVICE.
Motor overload protection trips
out after a short time.
Fault in the power supply. Check power supply.
Motor fault. Call KAESER SERVICE.
Motor overload protection trips
out after a long time.
Current too high because of low
supply voltage.
Check power supply cable con‐
ductor cross-sections.
Check and tighten connection
terminals or screws.
The machine runs continuously
but maximum pressure is not
reached.
Air filter clogged. Maintain or replace the air filter.
Valves 1) or valve plate between
cylinder head and cylinder are
leaking or dirty.
Have the valve 1) or valve plate
replaced by a
KAESER SERVICE technician.
Broken pressure valve reed. Have valve plate replaced.
Machine leaks air. Seal the leaks or replace the
components.
Leakage from an air consumer
connected to the air system.
Check possible leakage points.
The air demand is greater than
the machine's air delivery ca‐
pacity.
Use a larger machine.
Solenoid valve blows off contin‐
uously. Solenoid coil is defec‐
tive.
Replacing the solenoid valve.
Machine cuts in and out too of‐
ten.
External air receiver filled with
condensate.
Drain condensate.
Machine switches off. Undervoltage trip in the user's
pressure switch of the oil level
indication (option C5) activated.
Top up the oil.
Switch on the machine at the
pressure switch.
The machine switches off and
air escapes from the venting
valve.
The user's check valve is de‐
fective.
Replace the check valve.
The venting valve loses air
while the machine is running.
The venting valve is not clos‐
ing.
Maintain or replace the unload‐
ing valve.
The user's pressure switch
does not vent after switching
off.
