Close the cover of the dry ice con-

tainer.
NOTICE
To avoid disturbances due to aggluti-
nated dry ice pellets, it is useful to fully
use up the contents of the dry ice con-
tainer before adding fresh dry ice. If the
machine is to remain idle for a longer
time, operate the device until the dry
ice container is empty or empty the
container via the dry ice emptying func-
tion.
Settings
NOTICE
The settings depend on the substanc-
es contained in the detergent and the
type of dirt.
Release emergency-stop button by

turning.
Set the appliance switch to "I".

Turn the keyswitch in a clockwise

direction.
Increase/reduce the jet pressure by

using the respective keys.
NOTICE
The higher you set the jet pressure, so
much greater (more agressive) will the
cleaning effect be.
Increase/reduce the dry ice dosing

by using the respective keys.
Turn the keyswitch counter-clock-

wise and remove the key.
The automatic closure of the key
hole will prevent contamination dur-
ing operation.
When the key is removed, the de-
vice is protected against changes to
the settings and resetting the statis-
tics values.
Operation
Carry out maintenance jobs "daily

before starting work" (see section
"Maintenance and Care").
DANGER
Risk of injury on account of flying dry
ice pellets. Do not direct the jet pistol
on persons. Keep third persons away
from the place of use and when the
machine is being operated (by cordon-
ing off the area).
Do not touch/hold the nozzle opening
or the dry ice jet when the machine is
running.
First stop the compressed air supply
before disconnecting the jet gun from
the spray agent hose and the spray
agent hose from the device; remove all
pressure from the system and then pull
the plug out of the socket.
Cordon off the working area to pre-

vent persons coming close to the
machine when it is being operated.

DANGER
Risk of suffocation on account of car-
bon dioxide. The dry ice pellets are
made of solidified carbon dioxide. The
carbon dioxide content in the air at the
place where the machine is used will
increase when the machine is running.
Sufficiently ventilate the workstation
and use a personal warning device or
breathing apparatuses, if necessary.
Indication of high carbon dioxide con-
centration in the breathing air:
3...5%: headache, faster breathing.
–
7...10%: headache, nausea and
–
perhaps even unconsciousness.
If any of these symptoms occur, please
switch off the machine immediately and
get a breath of fresh air; improve the ven-
tilation before starting work again with the
machine or use respirators.
Carbon dioxide accumulates in lower
situated places. Prevent accumulation
by means of active ventilation meas-
ures.
Follow the safety specifications of the
manufacturer of dry ice.
DANGER
There is a danger because of danger-
ous to your health materials. If dust
that is dangerous to your health can be
generated, the appropriate safety
measures will have to be taken prior to
beginning work.
DANGER
Risk of explosion!
Do not work on light metals and iron-
containing substances simultaneously.
If you alternate between working on
light metals and iron-containing parts,
the work area and the suction device
must be cleaned between work cycles.
Danger due to dust explosion. If inflam-
mable dusts are formed during work,
accumulations of dust must be avoid-
ed. Regularly remove dust before criti-
cal amounts are accumulated.
Ensure adequate ventilation while

working in closed rooms in order to
keep the carbon dioxide concentra-
tion in the atmospheric air in the
room below the danger level.
Attach the object to be cleaned if

necessary.
DANGER
Risk of injury on account of electro-
static discharge; risk of damage to the
electronic components. The object be-
ing cleaned can get charged electrical-
ly during the cleaning process. Provide
suitable earthing for the object being
cleaned and ensure that the earthing
remains intact during the entire clean-
ing process.

WARNING
Risk of injury on account of tripping
and falling.
Lay spray agent hose and control line
in a way that they do not pose a risk of
stumbling during work.
CAUTION
Risk of damage by foreign objects fall-
ing into the dry ice container. Keep
cover of the dry ice container closed
during operation.
Connect the electrically conductive

earth wire to the object to be
cleaned or earth the object to be
cleaned in another way.
Wear safety gear, safety gloves,

close fitting safety goggles and ear-
protection.
Switch on the compressed air supply.

Release emergency-stop button by

turning.
Set the operating type for the com-

pressed air jet to "1" or dry ice jet to
"2" on the operating type switch of
the jet pistol.
Choose a safe place to stand, as-

sume a secure body stance to
avoid being thrown off-balance by
the recoil pressure of the jet pistol.
In order to prevent the sudden re-
coil, a gradual increase of the jet
pressure can be set up (see "Oper-
ation/Basic Setting", menu item
"soft start").
Press in the safety knob of the jet

pistol.
Activate the dry ice jet by pressing

the trigger of the jet pistol and carry
out the cleaning operation.
NOTICE
When using the Advanced jet pistol,
the dosing of dry ice pellets can be
switched on or off via the dry ice dosing
on/off key on the jet pistol. When the
dosing is turned off, the key illuminates
red, the display shows "ice off".
Moreover, when the Advanced jet pis-
tol is used, the jet pressure and the dry
ice quantity can be adjusted on the jet
pistol.
CAUTION
Risk of damage to the dosing equip-
ment on account of dirt. Keep the lid of
the dry ice container closed during the
spraying operation to prevent sprayed
off dirt from entering it.
Switch-off in case of emergency
Release the trigger of the jet pistol.

Press emergency-stop button.

The dry ice dosing is topped and the air
flow from the nozzle is interrupted.
Interrupt the compressed air sup-

ply.
