valve before unscrewing the extraction de-
vice. The gas bottle still has considerable
residual pressure.
Before returning it, screw the locking nut and
the protective cover onto the gas bottle.
If the gas escapes uncontrolled, close the
bottle valve. If the gas emission cannot be
stopped, take the bottle outside or leave the
room, lock the access and only enter and
ventilate the room if a concentration meas-
urement rules out a danger.

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
