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 injuries 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 oper-
ation".
2. Cordon off the work area to prevent people from en-
tering during operation.
DANGER
Risk of asphyxiation
Risk of suffocation from carbon dioxide. The dry ice pel-
lets consist of solid carbon dioxide. The carbon dioxide
content of the air at the workplace increases when the
device is operated.
Lay the exhaust hose outdoors, for example, so that no-
body is endangered by 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).
For longer jet work (longer than 10 minutes per day) and
especially in small rooms (less than 300 m³), we recom-
mend 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 unconscious-
ness.
Turn off the device immediately and seek fresh air at the
first signs of these symptoms. 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 cleaning 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 device before
you work on the respective other 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 electrostatically
charged during the cleaning process. The subsequent
discharge can cause injuries and damage electronic as-
semblies.
Ground the object to be cleaned and maintain 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.
Note
Before starting the spraying work, the device must be
rinsed to remove any contamination or moisture.
1
Keep the shut-off valve of the CO2 cylinder closed.
2
Operate the device for 30 seconds with compressed
air only.
The "Compressed air/pellets" button must not be
pressed during this process.
After rinsing, work can be continued normally.
8. Open the stop valve on the carbon dioxide bottle.

10. Choose a safe place to stand and adopt a safe pos-
ture so as not to be unbalanced by the recoil force
of the jet gun.
Cleaning with dry ice pellets
1. Select operation with pellet jet using the com-
pressed air / pellets button. (The indicator light must
not light up.)

Off: Pellet jet
2. Set the jet pressure on the on-site pressure reducer
to the desired value. Maximum pressure: 10 bar.
Minimum 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 ex-
ceeded, the display flashes.
3. Point the jet gun away from your body.
4. Push the safety lever of the jet gun upwards 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.
ATTENTION
Risk of damage
Coarse pellets may possibly escape.
Check the cleaning performance on a non-visible area
first to avoid damage.
Note
If there are interruptions in the dry ice stream, increase
the blasting pressure or set a lower level on the pro-
gramme selector switch.
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 seconds.
9. Insert the jet gun with the retaining cone into the
holder on the device.

10. Close the stop valve on the carbon dioxide bottle if
the work break lasts longer than 30 minutes.
Compressed air without pellet jet
Loose dirt can be removed with compressed air without
dry ice pellets.
1. Select operation with compressed air using the
compressed air/pellets button. (The indicator light
must light up red.)
