1. Replace oil with corrosion inhibitor oil
(viscosity SAE 30). See Chap. 2.6.7.
2. Allow the compressor to warm up, switch
it off, disconnect the power supply.
3. Drain the condensate, depressurise the
compressor.
4. Prior to returning to operation, replace
corrosion inhibiting oil with compressor
oil.
Store the compressor in a dust-free and dry
area where it is not exposed to high tem-
perature fluctuations.
2.7.2 Environment
Do not dispose of the device in
household waste!
Recycle de-
vices, accessories and packaging.
Observe applicable national regu-
lations.
EU only:
In accordance with European Di-
rective on waste electrical and electronic
equipment and implementation in national

mentally friendly recycling.
2.8 Troubleshooting
Problem
Cause
Remedy
A Protective motor
switch interrupts
power supply
In case of malfunctions (e.g.
overheating; low voltage;
extension cable too long or
with incorrect cross-section),
the protective motor switch is
tripped.
Switch off the compressor. Wait a
short while. Actuate the protective
motor switch is available. Switch on
the compressor.
Protective motor switch trips again:
switch off compressor. Disconnect
the power supply. Contact the ser-
vice partner
B Pressure relief
does not function
Power failure / undervoltage in
mains with compressor
switched on
Switch off the compressor. It de-
pressurises. Switch on the com-
pressor
C Compressor does
not start when
switched on.
Vessel pressure is higher than
switch-on pressure.
Relieve pressure in the vessel until
the pressure switch is activated au-
tomatically.
Power supply faulty.
Have the power supply checked by
a qualified person (service partner).
Protective motor switch inter-
rupts power supply.
See item A.
Pressure switch defective
Have the pressure switch changed
by a qualified person.
D Compressor
starts up briefly /
buzzes and then
switches off
automatically
Mains connection cable longer
than permitted or the cross
section is too small
Check connection cable length and
cable cross-section (see
Chap. 2.4.4)
E Compressor runs
continuously
Intake filter badly contami-
nated
Clean or replace
Air consumption of compressed
air tools is too high
Check air consumption. Contact the
service partner
Leakage at compressor
Locate leak, contact service partner
Excessive condensate in the
tank
Drain the condensate (see
Chap. 2.6.5)
Compressed air line leaky
Check the compressed air network,
seal leak
Condensate drain valve is open
or missing
Close or replace
