Fault
Remedy
Possible cause
Machine runs but produces
no compressed air.
Inlet valve not opening or
only opening partially.
no compressed air.
Venting valve not closing.
Leaks in the pressure sys-
tem.
Check pipework and con-
nections for leaks and
tighten any loose fittings.
Air consumption is greater
than the capacity of the
compressor.
Check compressed air net-
work for leaks.
Shut down the consumer(s).
Hose coupling or mainten-
ance hose still plugged into
the quick ---release coupling
on the oil separator tank.
Remove coupling or main-
tenance hose.
Cooling oil runs out of the
air filter.
Oil level in the oil separator
tank too high.
Drain off oil until the correct
level is reached.
air filter.
Inlet valve defective.
Compressor switches be-
tween load and idle (off
Air receiver too small.
Compressor switches be-
tween load and idle (off
load) more than twice per
minute.
Flow into the compressed
air network restricted.
Increase air pipe diameters.
Check filter elements.
Switching difference too
small (e.g. p1 SD)
Cooling oil leaking into the
floor pan.
Hose coupling or mainten-
ance hose still plugged into
the quick ---release coupling
on the oil separator tank.
Remove coupling or main-
tenance hose.
Oil cooler leaking
Connections leaking.
Tighten connection fittings.
Replace seals.
Cooling oil consumption too
high.
Unsuitable oil is being used.
Use SIGMA FLUID cooling
oil.

Oil separator cartridge split.
Change the oil separator
cartridge.
Oil level in the oil separator
tank too high.
Drain off oil until the correct
level is reached.
Oil return line clogged.
Check dirt trap in the oil re-
turn line.
