Safety devices

Safety devices protect the user and may not be disabled
or functionally circumvented.
Pressure regulator
The pressure regulator keeps the boiler pressure as
constant as possible during operation. The heating is
switched off when the maximum operating pressure in
the boiler has been reached and switched on again
when the pressure in the boiler drops due to steam re-
moval.
Water shortage thermostat
The heating temperature rises when the water in the
boiler runs out. The water shortage thermostat switches
the heating off and the "Water shortage" indicator light
lights up red. The heating cannot be switched on again
until the boiler has cooled down or is refilled.
Safety thermostat
● If the water shortage thermostat fails and the device
overheats, the safety thermostat switches the de-
vice off.
● Before resetting of the safety thermostat, contact
the responsible KÄRCHER Customer Service.
Safety lock
● The safety lock seals the steam boiler against the
steam pressure present. If the pressure regulator is
defective and overpressure occurs in the steam boil-
er, an pressure relief valve opens in the safety lock
and steam escapes through the lock.
● Before re-commissioning the device, contact the re-
sponsible KÄRCHER Customer Service.

Cleaning methods

Freshening textiles
Always check the compatibility of the textiles at a con-
cealed point before using the device on textiles: First
steam the textile, allow it to dry and then check it for any
change in colour or shape.

Cleaning of coated or painted surfaces
Wax, furniture polish, plastic coatings or paint can come
off or stains may occur when cleaning painted or plastic-
coated surfaces such as e.g. kitchen and living room
furniture, doors, parquet or linoleum. To clean these sur-
faces, steam a cloth briefly and wipe it over the surfac-
es.
Preheat the window pane in seasons with particularly
low temperatures. To do this, lightly steam the entire
glass surface at a distance of approx. 50 cm. This
avoids tension on the surface that can lead to glass
breakage.
Installing accessories
1. Open the cover of the device socket and plug the
steam connector tightly into the device.
2. Connect the accessory (floor nozzle, manual nozzle
or spotlight nozzle) to the steam gun. Push the parts
together until the locking button on the steam gun
engages.
3. Use extension tubes (special accessories) if neces-
sary. Push the parts together until the respective
locking button engages.
4. Press the locking button to separate the accesso-
ries.
Note
Do not fill with pure distilled water! Use a maximum of
50% distilled water mixed with tap water.
1. Unlock and open the device cover.
2. Check that the safety lock is seated tightly.
3. Remove the fresh water tank.

4. Open the reservoir cap of the fresh water tank.
5. Pour approximately 0.5 litres of tap water into the
fresh water tank.
Do not use detergents!
6. Close the reservoir cap.
7. Fit the fresh water tank.
8. Close and lock the device cover.
Switching on the device
● The heating switches on periodically during use (in-
dicator light lights up red) to maintain the pressure in
the boiler.
● If the device is switched on without water, the "Heat-
ing" indicator light lights up red until the water short-
age thermostat switches the heating off. The "Water
shortage" indicator light then lights up red.
1. Plug the mains plug into a mains socket.
2. Unlock and open the device cover.
Note
The device cover must remain open during operation so
that the indicator lights can be seen.
3. Switch on the device with the Heating switch. The
indicator light lights up red.
Note
The full heating capacity is only available if the steam
connector is connected to the device when it is heating
up. The system is ready for operation. when the "Heat-
ing" indicator light lights up green.
