2.5.1 Insert
1. Plug in the power plug.
2. Connect the compressed air hose to the
quick-action coupling of the compressor.
It is locked automatically.
3. Then, connect the consumer.
4. Switch on the compressor at the ON/OFF
switch (item 10). The compressor starts
up and switches off automatically at
maximum pressure: it is ready to use.
When the switch-on pressure is reached, the
compressor restarts automatically.
2.5.2 Adjusting the working
pressure
1. Turn the pressure reducer fully clockwise
to 8 bar.
2. Then turn the reducer anticlockwise to
the required pressure setting.
Observe the specifications for compressed
air tools/units.
2.5.3 After use
1. Switch off the compressor.
2. Disconnect the power supply.
3. Disconnect the plug nipple of the com-
pressed air hose from the quick-action
coupling.
4. Clean the compressor if necessary (see
Chap. 2.6.2).
5. Depressurise the compressor (see Chap.
2.6.1).
6. Transport the compressor to the storage
location (see Chap. 2.4.1).
2.6 Maintenance
Observe the safety instructions!
2.6.1 Before each maintenance
task
1. Swtich on the compressor at the ON/OFF
switch (item 10). Disconnect the power
supply.
2. Depressurise the compressor: using the
blow gun, blow out all pressure from the
vessel.
2.6.2 Cleaning the compressor
• Clean the cooling fins on the cylinder, cyl-
inder head and aftercooler using com-
pressed air.
• Clean the fan impeller cover on the motor.
2.6.3 Draining condensate from
pressure vessel
L
Condensate is a water pollutant. Dispose
of it according to applicable regulations!
1. Place a suitable vessel under the conden-
sate drain.
2. To drain condensate, the pressure may
be no more than 2 bar.
3. Open the condensate drain valve
(item 09): rotate 1 1/2 turns anticlock-
wise.
4. Rotate the condensate drain valve clock-
wise to block it.
