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 device, especially the abrasive hose,
to ensure that they are in good condition.
Replace damaged assemblies with flaw-
less ones. Clean soiled assemblies and
check that they are working properly.
ATTENTION
Risk of damage
Condensation water can drip from the de-
vice casing onto the floor.
Do not operate the device on surfaces that
are sensitive to moisture.
1. Open the drain tap and drain the con-
densation water that has collected in the
device.
2. Close the drain tap.
3. Store the device on a level and flat sur-
face.
4. Block the steering rollers with the park-
ing brakes.
5. Connect the abrasive hose to the cou-
pling 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 ca-
ble and tighten 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, carbon dioxide leads
to unconsciousness, respiratory arrest and
death. The maximum workplace concentra-
tion is 0.5%. Carbon dioxide is heavier than
air and collects in pits, basements and de-
pressions.
Lay the exhaust hose so that nobody is en-
dangered by the escaping carbon dioxide.
Note: Carbon dioxide is heavier than air.
Make sure that carbon dioxide does sink to
lower-lying areas, for example by flowing
from the outside into a basement below the
workshop (flows).
10.Lay the exhaust hose outdoors or con-
nect it to an extraction device.
Changing the jet nozzle
The jet nozzle on the jet gun can be ex-
changed in order to adapt the device to the
material and degree of contamination of the
object to be cleaned.
DANGER
Risk of injury
The device 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 protective 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 en-
gaged when the pin no longer protrudes
from the casing. The jet nozzle can be
rotated to the desired orientation.
Connecting compressed air
Note
For trouble-free operation, the compressed
air must have a low moisture content (max-
imum 5% relative humidity, dew point below
English
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 separa-
tor 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
2
● Riser bottle for withdrawing liquid CO
● The CO quality must correspond to the
2
specifications in the chapter "Intended use".
● CO2 bottle without residual pressure
valve or check valve.
ATTENTION
Malfunctions
A residual pressure valve or check valve
connected to the CO bottle prevents ex-
2
traction of the required CO
2
Only use CO2 bottles without a residual
pressure valve / check valve. A residual
pressure valve can be recognized by the
smaller outlet diameter.

As the temperature rises, the effectiveness
of pellet production decreases and a larger
proportion of carbon dioxide 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 sur-
face.
2. Apply the parking brakes on both steer-
ing rollers.
3. Open both straps for the carbon dioxide
bottle.
4. Place the carbon dioxide bottle on the
storage space on the device.
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 trolley to the base by rotating it.
5. Place both straps around the carbon di-
oxide bottle, lock and tighten.
6. Unscrew the protective cover from the
carbon dioxide 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 di-
oxide hose and, if necessary, clean them
before connecting to the device.
Make sure that an undamaged seal is in-
serted between the bottle and the bottle
connection.
