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 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.
몇
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
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 de-
vice.
3. Slowly open the on-site compressed air
stop valve.
Connecting the carbon dioxide
bottle
Requirements for the CO
2
supply:
●
CO
2
bottle with dip tube for withdrawing
liquid CO
2
.
Note
CO
2
bottles with a dip tube (also called a
riser) are usually 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
2
quality must correspond to the
specifications in the chapter "Intended
use".
ATTENTION
Malfunctions
A residual pressure valve or check valve
connected to the CO
2
bottle prevents ex-
traction 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 between
the bottle and the unit.

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.
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 dioxide
bottle. Follow the separate instructions
enclosed with the adapter.
8. Connect the bottle connection to the car-
bon dioxide filter on the carbon dioxide
bottle.
Make sure that a sealing ring bottle con-
nection in perfect condition is inserted
between the screw flange and the car-
bon dioxide bottle.
9. 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 di-
oxide 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 electrician 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 ac-
cessible 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 operator.
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 oper-
ate the device with a damaged power ca-
ble. Have a damaged cable replaced by a
qualified electrician.
The extension cable must ensure IPX4 pro-
tection and the cable design must at least
comply with H 07 RN-F 3G1.5.
Unsuitable extension cables can be dan-
gerous. If an extension cable is used, it
must be suitable for outdoor use 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.
Reset jet time
To account for working hours, the jet time
counter can be reset to 0 before work be-
gins.
1. Turn the program switch to the "Reset"
position.

Operation
DANGER
Risk of injury
Dry ice pellets flying around can cause inju-
ries or cold burns.
Do not point the jet gun at people. Remove
third parties from the operating location and
keep them away (e.g. via barriers) during
operation. Do not touch the nozzle or the
dry ice jet during operation.
1. Carry out all maintenance work from the
chapter "Care and maintenance / daily
before starting operation".
