Symbols on the unit
Danger from flying dry ice pellets.
Do not point the jet gun at people.
Remove third parties from the oper-
ating location and keep them away
(e.g. via barriers) during operation.
Do not touch the nozzle or the dry
ice jet during operation.
Risk of suffocation from carbon
dioxide.
During operation, the carbon dioxide
content of the air at the workplace in-
creases.
Make sure there is sufficient air ex-
change at the workplace.
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 levels of carbon dioxide:
3...5%: Headache, high breathing rate.
7...10%: Headache, nausea, possibly unconscious-
ness.
If these symptoms occur, switch off the device immedi-
ately and get some fresh air. Before continuing work, im-
prove ventilation or use a breathing apparatus.
Carbon dioxide is heavier than air and collects in con-
fined spaces, lower-lying spaces or in closed contain-
ers. Ensure adequate ventilation at the workplace.
Observe the safety data sheet from the carbon dioxide
supplier.
Risk of injury, risk of damage from
electrostatic charging.
The cleaning object can become electro-
statically charged during the cleaning
process.
Ground the object to be cleaned and
keep it grounded it until the cleaning process is com-
plete.
Risk of injury from electric shock.
Do not open the device. Work on the device may only
be performed by KÄRCHER Customer Service.
Risk of injury from cold burns.
Dry ice has a temperature of -79 °C. Do
not touch the dry ice or cold parts of the
unit.
Risk of injury from carbon dioxide
bottle falling over, Danger of suffoca-
tion due to carbon dioxide
Attach the carbon dioxide bottle securely.
Risk of injury from flying dry ice pel-
lets and dirt particles.
Wear safety goggles.
Danger of hearing damage.
Wear hearing protection.
Risk of injury from flying dry ice pel-
lets and dirt particles.
Wear protective gloves according to EN
511.
Risk of injury from flying dry ice pel-
lets and dirt particles.
Wear long-sleeved protective clothing.
Caution! Permanent malfunctions
possible.
Traces of fat or oil interfere with the for-
mation of dry ice snow in the device. Do
not use grease, oil or other lubricants on the connection
nozzle or on the thread of the carbon dioxide bottle or
the carbon dioxide hose.
General safety instructions
DANGER
Risk of injury
The device may start up unexpectedly.
Unplug the mains plug from the power socket before
working on the device.
Risk of injury
Dry ice and cold device parts can cause cold burns on
contact with the skin.
Wear cold protection clothing or allow the device to
warm up before working on the device.
Never put dry ice in your mouth.
Risk of injury
The dry ice jet can be dangerous if used improperly.
10
Do not direct the dry ice jet at persons, live electrical
equipment or at the device itself.
Do not aim the dry ice jet at yourself or others, e.g. to
clean clothes or shoes.
Risk of injury
Light objects can be blasted away by the dry ice jet.
Fix light objects in place before starting cleaning.
Risk of asphyxiation
Increased concentration of carbon dioxide in the air you
breathe can lead to death from suffocation.
Make sure that no exhaust gases are emitted close to
air vents.
Provide adequate ventilation in the workplace and en-
sure that the exhaust gases are properly discharged.
WARNING
Risk of injury
The recoil force of the jet gun can throw you off balance.
Find a safe place to stand and hold the jet gun firmly be-
fore you pull the trigger.
Risk of injury
Dry ice pellets and dirt particles can hit and injure peo-
ple.
Do not use the device when other people are within
range unless they are wearing protective clothing.
Do not use the device if a power cable or important parts
of the device are damaged, e.g. safety devices, abra-
sive hose, jet gun.
Safety instructions for gas bottles
DANGER
Risk of bursting, risk of suffocation
Gas bottles can burst if they become too hot or if they
are mechanically damaged. Leaking carbon dioxide can
cause death by suffocation.
Protect gas bottles from excessive heat, fire, dangerous
corrosion, mechanical damage and unauthorized ac-
cess.
Store gas bottles so that no escape routes are restrict-
ed.
Do not store gas bottles in underground rooms, on and
at stairs, in hallways, corridors and garages.
Do not store gas bottles together with flammable mate-
rials.
Store gas bottles upright.
Secure gas bottles against tipping over or falling.
Close the bottle valve before transporting gas bottles.
Transport gas bottles with a gas bottle cart or a vehicle
and secure the bottles against falling.
Pull on the protective cover before lifting the gas bottle
to check that the protective cover is securely in place.
Secure the gas bottle at the point of use against falling
over.
Do not open the bottle valve to check the pressure.
Open and close the bottle valve only by hand without
the aid of tools.
Check the bottle valve/device connection for leaks.
Close the bottle valve during work breaks and at the end
of work to prevent uncontrolled gas escaping.
Only empty gas bottles so far that a small residual pres-
sure remains in the bottle in order to prevent foreign
matter from entering.
When the gas bottle has been emptied to the residual
pressure, first close the bottle valve before unscrewing
the extraction device. The gas bottle still has consider-
able residual pressure.
Before returning it, screw the locking nut and the protec-
tive 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 en-
ter and ventilate the room if a concentration measure-
ment rules out a danger.
