tween the jet pistol and the nozzle.
16
Handle (accessory)
The handle can be fastened on the exten-
sion piece.
Working light (accessory)
The working light is connected between the
jet pistol and the nozzle. Switching on and
switching off is described in the chapter
"Operation/Basic Settings".
Connect compressed air supply
Note
To ensure smooth functioning of the ma-
chine, the compressed air must have a low
moisture content (max. 5% relative humidi-
ty, dewing point below 0°C). The com-
pressed air must also be free from oil, dirt
and foreign particles.
The compressed air must be dry and oil-
free, at least one aftercooler and a separa-
tor must be downstream of the compressor.
 Close pressure relief valve.
 Connect the compressed air inlet pipe
to the compressed air connection point
of the device.
The maximum permissible supply pres-
sure of 1 MPa (10 bar) must not be ex-
ceeded.
Establish mains contact
Danger
Risk of electric shock.
The socket to be used must have been in-
stalled by an electrician and be compliant
with IEC 60364-1.
The appliance may only be connected to a
electricity source with proper earthing.
The socket used must be accessible and at
a height between 0.6 m and 1.9 m off the
floor.
The socket used must be in the viewing
area of the operator.
The machine must have an FI fuse of type
B, 30 mA.
Check the mains cables of the machine
each time before using the machine to see
that it is not damaged. Never operate a ma-

chine with damaged cables. Get the dam-
aged cables replaced by an electrician.
The extension cord must be protected by
IPX4 safety mechanism and the cables
must at least be compliant with H 07 RN-F
3G1.5.
 Insert the mains plug into the socket.

Operation

Filling dry ice
Danger
Risk of cold burns. Dry ice has a tempera-
ture of -79 °C. Never touch dry ice or cold
parts of the machine without appropriate
protection. Wear protective gloves and pro-
tective overalls.
 Open the cover of the dry ice container.
 Check the dry ice container for pres-
ence of foreign particles and conden-
sate, remove them if found.
 Fill dry ice pellets into the container.
Caution
Risk of damage to the device. Use only dry
ice pellets as jet medium. The use of any
other spray agent will lead to loss of war-
ranty coverage.
 Close the cover of the dry ice container.
Note
To avoid disruptions in operations on ac-
count of melted dry ice pellets, it would
make sense to fully use up the contents of
the dry ice container before adding fresh
dry ice. If the machine is to remain idle for
a longer time, operate the device until the
dry ice container is empty or empty the con-
tainer via the dry ice emptying function.
Settings
Note
The settings depend on the substances
contained in the detergent and the type of
dirt.
 Release emergency-stop button by
turning.
 Set the appliance switch to "I".
 Turn the keyswitch in a clockwise direc-
tion.
 Increase/reduce the jet pressure by us-
ing the respective keys.
Note
The higher you set the jet pressure, so
much greater (more agressive) will the
cleaning effect be.
 Increase/reduce the dry ice dosing by
using the respective keys.
 Turn the keyswitch counter-clockwise
and remove the key.
The automatic closure of the key hole
will prevent contamination during oper-
ation.
When the key is removed, the device is
protected against changes to the set-
tings and resetting the statistics values.
