Troubleshooting

Observe the safety instructions!
Problem
A Protective motor
switch interrupts
power supply.
B Pressure relief does
not function
II/18
Cause
In case of malfunctions (e.g.
overheating; low
extension cable too long or
with incorrect cross-section),
the protective motor switch is
tripped.
The pressure relief is shut
down by an interruption of the
power supply or voltage drop
in the mains when the com-
pressor is switched on.
2.7.1 Preservation
Preservation of oil-lubricated compressors is
necessary if the compressor is taken out of
service for a long period (over 6 months) or
is new from the factory and will not be oper-
ated until much later.
1. Switch off the compressor. Disconnect
the power supply.
2. Allow the oil to drain. See Chap. 2.6.6.
3. Fill corrosion inhibiting oil (viscosity SAE
30). Insert the oil filler plug or oil dip-
stick.
4. Allow the compressor to warm up, switch
it off.
5. Refit intake filter, seal watertight with
Scotch tape.
6. Switch off the compressor. Disconnect
the power supply.
7. Drain condensate.
8. Depressurise the compressor.
Store the compressor dry and do not subject
it to large temperature fluctuations.
2.7.2 Disposal
Dispose of the unit and packaging materials
according to applicable regulations.
Remedy
X Switch off the compressor. Wait a
voltage; short while. For compressors
with an external protective motor
switch:
Switch on the compressor.
If the protective motor switch is
triggered again: switch off the
compressor. Disconnect the pow-
er supply. Contact the service
partner.
X
Switch off the compressor. It de-
pressurises. Switch on the com-
