7. Connect the carbon dioxide hose with fil-
ter to the bottle.
8. Make sure that there is a seal between
the bottle and the hose.
9. Tighten the union nut lightly with an
open-end wrench.
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.
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 begins.
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".
2. Cordon off the work area to prevent peo-
ple from entering during operation.
DANGER
Risk of asphyxiation
Risk of suffocation from carbon dioxide.
The dry ice pellets consist of solid carbon
dioxide. The carbon dioxide content of the
air at the workplace increases when the de-
vice is operated.
Lay the exhaust hose outdoors, for exam-
ple, so that nobody is endangered by car-
bon dioxide.
14
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).
For longer jet work (longer than 10 minutes
per day) and especially in small rooms (less
than 300 m³), we recommend wearing a
carbon dioxide warning device.
Signs of high carbon dioxide concentration
in the air you breathe:
3...5%: Headache, high breathing rate.
7...10%: Headache, nausea, possibly un-
consciousness.
Turn off the device immediately and seek
fresh air at the first signs of these symp-
toms. Before continuing work, be sure to
improve the ventilation measures or use a
breathing apparatus.
Observe the safety data sheet provided by
the carbon dioxide supplier.
Danger from substances harmful to
health.
Substances removed from the object to be
cleaned are whirled up as dust.
Adhere to the appropriate safety measures
if harmful dusts can arise during the clean-
ing process.
Risk of explosion
A mixture of iron oxide and light metal dust
can ignite under unfavourable conditions
and generate intense heat.
Never work on light metals and ferrous
parts at the same time.
Clean the work area and the extraction de-
vice before you work on the respective oth-
er material.
3. When working in confined spaces, ensure
that there is sufficient air exchange to keep
the carbon dioxide concentration in the
room air below the dangerous level.
4. Fasten light cleaning objects in position.
DANGER
Danger of electrostatic discharge
The cleaning object can become electro-
statically charged during the cleaning pro-
cess. The subsequent discharge can cause
injuries and damage electronic assemblies.
Ground the object to be cleaned and main-
tain it during the cleaning process.
5. Electrically ground the object to be
cleaned.
6. Wear protective clothing, protective
gloves, tightly fitting safety goggles and
hearing protection.
7. Activate the compressed air supply.
8. Open the stop valve on the carbon diox-
ide bottle.
9. Turn the program switch to level 3.

Cleaning with dry ice pellets
1. Select operation with pellet jet using the
compressed air / pellets button. (The in-
dicator light must not light up.)

Lights up red: Compressed air jet
Off: Pellet jet
2. Set the jet pressure on the on-site pres-
sure reducer to the desired value. Mini-
mum pressure:
● Level 1: 0.7 bar
● Level 2: 1.4 bar
● Level 3: 2.8 bar
Note
The pressure is shown in the display. If the
minimum pressure is not reached or the
maximum pressure is exceeded, the dis-
play flashes.
3. Point the jet gun away from your body.
4. Push the safety lever of the jet gun up-
wards and at the same time activate the
trigger.

The working light switches on at the
same time as the pellet production.
5. Wait until the pellet jet has built up.
ATTENTION
Never operate the device without or with
an empty carbon dioxide bottle.
Use the program switch to select a higher
level or change the carbon dioxide bottle if
no pellets come out of the jet gun after 5
minutes of jet.
6. If necessary, turn the program switch
back to level 2 or 1.
7. Direct the pellet jet at the object to be
cleaned and remove the dirt with the jet.
8. Release the trigger.
The pellet jet stops.
The working light goes out after 30 sec-
onds.
9. Insert the jet gun with the retaining cone
into the holder on the device.

ide bottle if the work break lasts longer
than 30 minutes.
Compressed air without pellet jet
Loose dirt can be removed with com-
pressed air without dry ice pellets.
1. Select operation with compressed air
using the compressed air/pellets button.
(The indicator light must light up red.)
