operating instructions. In particular, all
safety instructions must be observed.
Store these operating instructions so that
they are available to the operator at all
times.
The operator of the unit must carry out a
risk assessment on site and ensure that op-
erators are instructed.

death.

● Indication of a potentially dangerous situ-
ation that may lead to severe injuries or

Symbols on the unit
Danger from flying dry ice
pellets.
Do not point the jet gun at
people. Remove third par-
ties from the operating loca-
tion 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 car-
bon dioxide content of the
air at the workplace increas-
es.
Make sure there is sufficient air exchange
at the workplace.
Lay the exhaust hose outdoors, for exam-
ple, so that nobody is endangered by car-
bon dioxide.
Note: Carbon dioxide is heavier than air.
Make sure that carbon dioxide does sink to
lower-lying areas, for example 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 recommend wearing a
carbon dioxide warning device.
Signs of high levels of carbon dioxide:
3...5%: Headache, high breathing rate.
7...10%: Headache, nausea, possibly un-
consciousness.
If these symptoms occur, switch off the de-
vice immediately and get some fresh air.
Before continuing work, improve ventilation
or use a breathing apparatus.
Carbon dioxide is heavier than air and col-
lects in confined spaces, lower-lying spac-
es or in closed containers. Ensure
adequate ventilation at the workplace.
Observe the safety data sheet from the car-
bon dioxide supplier.
12
Risk of injury, risk of damage
from electrostatic charging.
The cleaning object can be-
come electrostatically charged
during the cleaning process.
Ground the object to be cleaned and keep
it grounded it until the cleaning process is
complete.
Risk of injury from electric shock.
Do not open the device. Work on the device
may only be performed by KÄRCHER Cus-
tomer 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 di-
oxide bottle falling over, Dan-
ger of suffocation due to
carbon dioxide
Attach the carbon dioxide bottle
securely.
Risk of injury from flying dry
ice pellets and dirt particles.
Wear safety goggles.
Danger of hearing damage.
Wear hearing protection.
Risk of injury from flying dry
ice pellets and dirt particles.
Wear protective gloves accord-
ing to EN 511.
Risk of injury from flying dry
ice pellets and dirt particles.
Wear long-sleeved protective
clothing.
Caution! Permanent malfunc-
tions possible.
Traces of fat or oil interfere with
the formation 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 di-
oxide 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 im-
properly.
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 oth-
ers, 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.
English
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 emit-
ted close to air vents.
Provide adequate ventilation in the work-
place and ensure 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 before you pull the trigger.
Risk of injury
Dry ice pellets and dirt particles can hit and
injure people.
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, abrasive 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 access.
Store gas bottles so that no escape routes
are restricted.
Do not store gas bottles in underground
rooms, on and at stairs, in hallways, corri-
dors and garages.
Do not store gas bottles together with flam-
mable materials.
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 uncon-
trolled gas escaping.
Only empty gas bottles so far that a small
residual pressure remains in the bottle in
order to prevent foreign matter from enter-
ing.
When the gas bottle has been emptied to
the residual pressure, first close the bottle
