off again if the rotation direction is incor-
rect.
2. Unplug the power plug.
3. Three-phase plug with phase inverter:
press it in and rotate it by 180°. (Figure
2a)
Three-phase plug without phase invert-
er: reverse the phases in the plug.
Repeat step 1.
4. If direction of rotation has not changed:
contact service partner.
2.5 Operation

Do not overload the compressor: do not
exceed the max. number of switching cy-
cles and the ratio of operating time to
standstill!
2.5.1 Insert
Switch on the compressor at the ON/OFF
switch (item 10). The compressor starts up
and switches off automatically at maximum
pressure.
2.5.2 Adjusting the working pressure
1. Pull up the adjustment button on the
pressure reducer (fig. 3a).
2. Rotate clockwise = pressure is in-
creased. Rotate anticlockwise = pressure
is reduced.
3. Press the adjustment button down to
lock it in place.
2.5.3 After use
1. Switch off the compressor.
2. Disconnect the power supply.
3. Disconnect plug nipple of air hose from
(safety) quick-action coupling.
4. Clean compressor (Chap. 2.6.2), depres-
surise it (Chap. 2.6.1), transport to stor-
age location (Chap. 2.4.1).
2.6 Maintenance
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.

Only drain oil if the unit has been suffi-
ciently cooled.
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.
