Possible cause
Remedy
Machine runs but produces no
compressed air.
Inlet valve not opening or only
opening partially.
Call an authorized KAESER
service representative.
Venting valve not closing.
Call an authorized KAESER
service representative.
Leaks in the pressure system.
Check pipework and connec‐
tions for leaks and tighten any
loose connections.
Air demand is greater than the
capacity of the compressor.
Check the air system for leaks.
Shut down consumer(s).
Hose coupling or maintenance
hose still plugged into the
quick-release coupling on the
oil separator tank.
Remove coupling or mainte‐
nance hose.
Cooling oil runs out of the in‐
take filter.
Oil level in the oil separator
tank too high.
Drain off oil until the correct lev‐
el is reached.
Inlet valve defective.
Call an authorized KAESER
service representative.
Compressor switches be‐
tween LOAD and IDLE more
than twice per minute.
Receiver too small.
Increase size of receiver.
Airflow into the compressed air
network restricted.
Increase air pipe diameters.
Check filter elements.
The differential between cut-in
and cut-out pressure too is
small.
Check switching differential.
Cooling oil leaking into the ma‐
chine interior.
Hose coupling or maintenance
hose still plugged into the
quick-release coupling on the
oil separator tank.
Remove coupling or mainte‐
nance hose.
Oil cooler leaking.
Call an authorized
KAESER service representa‐
tive.
Leaking pipe joints.
Tighten pipe joints.
Replace seals.
Cooling oil consumption too
high.
Unsuitable oil is being used.
Change to SIGMA FLUID cool‐
ing oil.
Oil separator cartridge split.
Change the oil separator car‐
tridge.
Oil level in the oil separator
tank too high.
Drain off oil until the correct lev‐
el is reached.
Oil return line dirty.
Check the dirt trap strainer in
the oil return line.
