The device's installation location must
meet the following requirements:
 dry, cool, protected from frost
 firm, horizontal and level surface.
A
Danger!

correct installation.
Secure the device against rolling

away, tipping over and slipping.
 Do not pull the device by the hose
or power supply cable. Transport
the machine by the handle only.

Mains connection

B
Danger! High voltage
Operate machine in dry environment
only. 
ENGLISH
Operate machine only on a power
source complying with the following re-
quirements:
– outlets properly installed, earthed
and tested;
– fuse protection in accordance with
technical data.
Make sure that the mains cable is out
of the way so that it does not interfere
with the work and cannot be damaged.
Always check to see that the machine
is switched OFF before plugging in.
B
Check direction of rotation!
Depending on the phase sequence, the
motor can turn in the wrong direction.
This can damage the machine. There-
fore, after each new connection, check
the direction of rotation: the compres-
sor's V-belt pulley must turn in the di-
rection indicated by the arrow (on the
belt guard).
In case of wong direction, the phases
must be exchanged in the power cable
plug:
1. Unplug power cable.
2. Use a flat-blade screwdriver to ex-
change the phases as illustrated:
– Slightly depress button switch
(45).
– Turn switch by 180°.
45
Protect mains cable from heat, aggres-
sive liquids and sharp edges.
Use only extension cables with suffi-
cient lead cross section (see 'Technical
Data').
Do not stop the compressor by unplug-
ging, but switch OFF using the ON/OFF
switch.
Unplug after use.
