General notes
Read the original instructions
before using the device for the
first time and act in accordance with it.
Keep the original instructions for future ref-
erence or for future owners.
Intended use
● The device is used to remove dirt with
dry ice pellets that are accelerated by an
air jet.
● The dry ice pellets are produced in the
device. This requires liquid carbon diox-
ide from a riser bottle.
● The device may not be operated in a po-
tentially explosive atmosphere.
● The minimum air exchange specified in
the "Technical data" section must be ob-
served at the operating location.
● The casing of the device may only be re-
moved by KÄRCHER Customer Service
for maintenance purposes.
CO quality
2
To ensure trouble-free operation, the car-
bon dioxide used must at least comply with
the following specifications:
● Carbon dioxide technical, class 2.5 or
better
● Purity ≥ 99.5%
● Water content (H O) ≤ 250 ppm
2
● NVOC (oil and fat) ≤ 2 ppm
Function
Carbon dioxide snow is created via decom-
pression of liquid carbon dioxide. The gas-
eous carbon dioxide that also arises is
carried away from the workplace via the ex-
haust hose.
The carbon dioxide snow is pressed into
dry ice pellets in the device.
Compressed air reaches the jet gun via a
solenoid valve. The air pressure is con-
trolled by an on-site pressure reducer.
When the trigger of the jet gun is activated,
the valve opens and the air jet emerges
from the jet gun. Dry ice pellets are addi-
tionally dosed into the air jet via a dosing
device.
The dry ice pellets hit the surface to be
cleaned and remove the dirt. The -79 °C
11
cold dry ice pellets also create thermal
11
stresses between the dirt and the object to
11
be cleaned, which also contribute to the
11
loosening of the dirt. In addition, the dry ice
11
immediately turns into gaseous carbon di-
oxide when it hits the surface, thus taking
up 700 times its volume. Dirt penetrated by
the dry ice is blown away as a result.
Environmental protection
The packing materials can be recy-
cled. Please dispose of packaging in
accordance with the environmental regula-
tions.
Electrical and electronic appliances
contain valuable, recyclable materials
and often components such as batter-
ies, rechargeable batteries or oil, which - if
handled or disposed of incorrectly - can
pose a potential threat to human health and
the environment. However, these compo-
nents are required for the correct operation
of the appliance. Appliances marked by this
symbol are not allowed to be disposed of
together with the household rubbish.

Safety instructions
The device may only be operated by per-
sons who have read and understood these
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 device must carry out a
risk assessment on site and ensure that op-
erators are instructed.
Hazard levels
DANGER
● Indication of an imminent threat of danger
that will lead to severe injuries or even
death.
WARNING
● Indication of a potentially dangerous situ-
ation that may lead to severe injuries or
even death.
CAUTION
● Indication of a potentially dangerous situ-
ation that may lead to minor injuries.
ATTENTION
● Indication of a potentially dangerous situ-
ation that may lead to damage to proper-
ty.
Symbols on the device
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.
English
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.
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 device.
Risk of injury from a falling
carbon dioxide bottleRisk of
suffocation from carbon diox-
ide
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.
