Initial startup
DANGER
Risk of injury
Dry ice pellets can escape from damaged components
and cause injuries.
Before initial startup, check all components of the de-
vice, especially the abrasive hose, to ensure that they
are in good condition. Replace damaged assemblies
with flawless ones. Clean soiled assemblies and check
that they are working properly.
ATTENTION
Risk of damage
Condensation water can drip from the device casing on-
to the floor.
Do not operate the device on surfaces that are sensitive
to moisture.
1. Open the drain tap and drain the condensation wa-
ter that has collected in the device.
2. Close the drain tap.
3. Store the device on a level and flat surface.
4. Block the steering rollers with the parking brakes.
5. Connect the abrasive hose to the coupling on the
device.

6. Unscrew the union nut of the abrasive hose and
slightly tighten it with an open-end wrench.
7. Plug the control cable into the device.
8. Screw on the union nut of the control cable and tight-
en by hand.
9. Insert the jet gun with the retaining cone into the
holder on the device.
DANGER
Risk of asphyxiation
Carbon dioxide escapes from the exhaust hose. From a
concentration of 8 percent by volume in the breath, car-
bon dioxide leads to unconsciousness, respiratory ar-
rest and death. The maximum workplace concentration
is 0.5%. Carbon dioxide is heavier than air and collects
in pits, basements and depressions.
Lay the exhaust hose so that nobody is endangered by
the escaping carbon dioxide.
Note: Carbon dioxide is heavier than air. Make sure that
carbon dioxide does sink to lower-lying areas, for exam-
ple by flowing from the outside into a basement below
the workshop (flows).
10. Lay the exhaust hose outdoors or connect it to an
extraction device.
Changing the jet nozzle
The jet nozzle on the jet gun can be exchanged in order
to adapt the device to the material and degree of con-
tamination of the object to be cleaned.
DANGER
Risk of injury
The unit can start unintentionally and cause injuries and
cold burns from the jet of dry ice pellets.
Set the program switch to "0/OFF" before removing the
nozzle.
WARNING
Risk of injury
Immediately after use, the nozzle is very cold and can
cause cold burns if touched.
Let the nozzle thaw before replacing it or wear protec-
tive gloves.
ATTENTION
Risk of damage
Do not operate the device if no jet nozzle is attached to
the jet gun.
1. Press the unlocking button down and pull the jet
nozzle out of the jet gun.

2. Press the other jet nozzle into the jet gun until it
clicks into place.
Note: The jet nozzle is correctly engaged when the
pin no longer protrudes from the casing. The jet noz-
zle can be rotated to the desired orientation.
Connecting compressed air
Note
For trouble-free operation, the compressed air must
have a low moisture content (maximum 5% relative hu-
midity, dew point below 0°C). The compressed air must
be free of oil, dirt and foreign bodies.
The compressed air must be dry and oil-free, at least
one aftercooler and a separator must be connected
downstream of the compressor.
The compressed air supply must be equipped with an
on-site pressure reducer.
1. Don personal protective equipment.
2. Connect a compressed air hose to the compressed
air connection on the device.
3. Slowly open the on-site compressed air stop valve.
Connecting the carbon dioxide bottle
Requirements for the CO supply:
2
● CO bottle with dip tube for withdrawing liquid CO
2
Note
CO bottles with a dip tube (also called a riser) are usu-
2
ally marked with a large "T" on the bottle or the back of
the bottle.
In some cases, the dip tube is additionally symbolised
by a vertical colour line on the bottle.
● The CO quality must correspond to the specifica-
2
tions in the chapter "Intended use".
ATTENTION
Malfunctions
A residual pressure valve or check valve connected to
the CO bottle prevents extraction of the required CO
2
amount.
If a CO2 bottle with residual pressure valve is used, the
ABS residual pressure valve (order number 2.574-
006.0), available as an accessory, must be installed be-
tween the bottle and the unit.

As the temperature rises, the effectiveness of pellet pro-
duction decreases and a larger proportion of carbon di-
oxide is released in gaseous form via the exhaust hose.
Store carbon dioxide bottles as cool as possible (below
31 °C) and protect them from heat, solar radiation and
heat during operation.
1. Push the device onto a level, stable surface.
2. Apply the parking brakes on both steering rollers.
3. Open both straps for the carbon dioxide bottle.
4. Place the carbon dioxide bottle on the storage
space on the device.
English
Note: If the carbon dioxide bottle is transported on a
bottle cart, the front edge of the floor area on the
transport cart can be placed on the surface of the
device. The bottle can then be moved from the trol-
ley to the base by rotating it.
5. Place both straps around the carbon dioxide bottle,
lock and tighten.
6. Unscrew the protective cover from the carbon diox-
ide bottle.
ATTENTION
Malfunctions possible
Traces of fat interfere with the formation of dry ice snow
in the device.
Check the connection nozzle and thread of the carbon
dioxide bottle and the carbon dioxide hose and, if nec-
essary, clean them before connecting to the device.
Make sure that an undamaged seal is inserted between
the bottle and the bottle connection.
7. For bottles with residual pressure valve, attach the
ABS residual pressure valve (order number 2.574-
006.0), available as an accessory, to the carbon di-
oxide bottle. Follow the separate instructions en-
closed with the adapter.
8. Open the CO bottle valve briefly (approx. 1 second)
2
to remove any contamination.
9. Connect the bottle connection to the carbon dioxide
filter on the carbon dioxide bottle.
Make sure that a sealing ring bottle connection in
perfect condition is inserted between the screw
flange and the carbon dioxide bottle.
10. Lightly tighten the narrow union nut of the screw
flange with an open-end wrench or ring spanner
(e.g. 6.574-337.0). Hold the wide union nut with an
open-end wrench to prevent the carbon dioxide
hose from twisting.
ATTENTION
Do not put torsion (twist) on the carbon dioxide hose,
otherwise it may be damaged.
Establishing the voltage supply
DANGER
Risk of injury from electric shock
The power socket used must be installed by an electri-
cian and comply with IEC 60364-1.
The device may only be connected to a voltage supply
with protective earth.
The power socket used must be easily accessible and
at a height of between 0.6 m and 1.9 m above the floor.
The power socket used must be within sight of the op-
erator.
The device must be protected by an error current circuit
breaker, 30 mA.
Check the mains connection of the device for damage
before each use. Do not operate the device with a dam-
aged power cable. Have a damaged cable replaced by
a qualified electrician.
The extension cable must ensure IPX4 protection and
the cable design must at least comply with H 07 RN-F
3G1.5.
Unsuitable extension cables can be dangerous. If an ex-
tension cable is used, it must be suitable for outdoor use
.
2
and the connection must be dry and above the ground.
It is recommended to use a cable drum that holds the
socket at least 60 mm above the floor.
1. Plug the mains plug into the socket.
Switching off the LED work lighting
The jet gun is equipped with an LED light to illuminate
the working area. In normal operation, the working light
switches on as soon as the gun trigger is pulled. The
working light switches off automatically after the spray-
ing work has been completed and an after-running time
of 5 seconds has elapsed. The working light can be de-
activated so that it does not switch on automatically
2
when the jet starts.
1. Press and hold the compressed air / pellets button
with indicator light for 4 seconds.
The working light is deactivated and "LED OFF" ap-
pears on the display.
Note
After restarting the device, the working light is automat-
ically reactivated and must be deactivated again if nec-
essary
2. To switch it on again during operation, press and
hold the button again for 4 seconds.
"LED ON" appears on the display.
