Warning

Risk of injury. When the angle jet pipe is 

used, a torsional moment acts on the jet 

pistol in addition to the repulsion power. 

Hold the jet pistol tightly.

Start your work with low jet pressure and in-

crease the jet pressure as necessary.

The handle can be fastened on the exten-

sion piece.

(only with Advanced jet pistol)

The working light is connected between the 

jet pistol and the nozzle. Switching on and 

switching off is described in the chapter 

"Operation/Basic Settings".

Note

For failure-free operation the compressed 

air must have a low moisture content. The 

compressed air must also be free from oil, 

dirt and foreign particles.

The compressor must at least be equipped 

with aftercooler, oil and water separator.



Close pressure relief valve.



Connect the compressed air inlet pipe 

to the compressed air connection point 

of the device.

The maximum permissible supply pres-

sure of 1.6 MPa (16 bar) must not be 

exceeded.



Danger

Risk of electric shock.

The socket to be used must have been in-

stalled by an electrician and be compliant 

with IEC 60364-1. 

The machine must have an FI fuse of type 

B, 30 mA. 

Check the mains cables of the machine 

each time before using the machine to see 

that it is not damaged. Never operate a ma-

chine with damaged cables. Get the dam-

aged cables replaced by an electrician.

The extension cord must be protected by 

IPX4 safety mechanism and the cables 

must at least be compliant with  H 07 RN-F 

3G1.5.



Insert the mains plug into the socket. 



Danger

Risk of cold burns. Dry ice has a tempera-

ture of -79 °C. Never touch dry ice or cold 

parts of the machine without appropriate 

protection. Wear protective gloves and pro-

tective overalls.



Open the cover of the dry ice container.



Check the dry ice container for pres-

ence of foreign particles and conden-

sate, remove them if found.



Fill dry ice pellets into the container.

Caution

Risk of damage to the device. Use only dry 

ice pellets as jet medium. The use of any 

other spray agent will lead to loss of war-

ranty coverage.



Close the cover of the dry ice container.

Note

To avoid disturbances due to agglutinated 

dry ice pellets, it is useful to fully use up the 

contents of the dry ice container before 

adding fresh dry ice. If the machine is to re-

main idle for a longer time, operate the de-

vice until the dry ice container is empty or 

empty the container via the dry ice empty-

ing function.

Note

The settings depend on the substances 

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 direc-

tion.



Increase/reduce the jet pressure by us-

ing the respective keys.

Note

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-clockwise 

and remove the key.

The automatic closure of the key hole 

will prevent contamination during oper-

ation.

When the key is removed, the device is 

protected against changes to the set-

tings and resetting the statistics values.



Carry out maintenance jobs "daily be-

fore starting work" (see section "Mainte-

nance and Care").



Danger

Risk of injury on account of flying dry ice 

pellets.  Do not direct the jet pistol on per-

sons.  Keep third persons away from the 

place of use and when the machine is being 

operated (by cordoning 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 prevent 

persons coming close to the machine 

when it is being operated. 



Danger

Risk of suffocation on account of carbon di-

oxide. The dry ice pellets are made of solid-

ified carbon dioxide. The carbon dioxide 

content in the air at the place where the ma-

chine is used will increase when the ma-

chine is running. Sufficiently ventilate the 

workstation and use a personal warning 

device or breathing apparatuses, if neces-

sary.

Indication of high carbon dioxide concen-

tration in the breathing air:

–

3...5%: headache, faster breathing.

–

7...10%: headache, nausea and per-

haps even unconsciousness.

If any of these symptoms occur, please 

switch off the machine immediately and get 

a breath of fresh air; improve the ventilation 

before starting work again with the machine 

or use respirators.

Carbon dioxide accumulates in lower situ-

ated places. Prevent accumulation by 

means of active ventilation measures.

Follow the safety specifications of the man-

ufacturer of dry ice. 



Danger

There is a danger because of dangerous to 

your health materials. If dust that is danger-

ous 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-con-

taining 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 inflamma-

ble dusts are formed during work, accumu-

lations of dust must be avoided. Regularly 

remove dust before critical amounts are ac-

cumulated. 



Ensure adequate ventilation while 

working in closed rooms in order to 

keep the carbon dioxide concentration 

in the atmospheric air in the room below 

the danger level.



Attach the object to be cleaned if neces-

sary.



Danger

Risk of injury on account of electro-static 

discharge; risk of damage to the electronic 

components. The object being cleaned can
