How to Use the Accessories

Important application instructions
Cleaning floor surfaces
It is recommended to sweep or vacuum the floor prior
to using the steam cleaner. This way, the floor is already
cleared of dirt/loose particles prior to the wet cleaning.
Refreshing textiles
Prior to treatment with the steam cleaner, always check
the reaction of the textiles in an inconspicuous location:
Steam at first, then let dry and then check for colour or
shape changes.
Cleaning of Coated or Lacquered Surfaces
When cleaning painted or plastic-coated surfaces, as
found on kitchen and living room furniture, doors, par-
quet; wax, furniture polish, plastic surfaces or paint can
come loose or stains can be created. When cleaning
these surfaces, briefly steam a cloth and wipe the sur-
faces with it.
ATTENTION
Never direct the steam jet at glued edges as the edge
band may loosen. Do not use the steam cleaner on un-
sealed wooden or parquet floors.
Cleaning of Glass
In case of low outside temperatures, especially in the
winter, warm up the window pane by slightly steaming
the entire glass surface. This will prevent tensions on
the surface which might lead to glass breakage.
Then clean the window surface with the hand nozzle
and attachment. Use a squeegee to remove the water
or wipe the surfaces dry.
ATTENTION
Do not direct steam onto the sealed locations of the win-
dow frame to prevent damage.
Steam nozzle
The steam nozzle can also be used without accesso-
ries, for example:
– to remove light wrinkles from hanging clothes by
steaming them at a distance of 10 to 20 cm.
– for moist dusting, by briefly steaming the cloth and
wiping the furniture with it.
Detail nozzle
The closer this nozzle is to the contaminated area, the
higher the cleaning effect, as the temperature and the
steam are highest at the nozzle output. Especially suit-
ed for cleaning difficult access locations, joints, fittings,
drains, sinks, toilets, blinds and heaters. Heavy lime
scale can be drenched in vinegar prior to steam-clean-
ing. Let the vinegar penetrate for about 5 minutes.
Round brush
The round brush can be installed onto the detail nozzle
as an accessory. Attached brushes can therefore be
used to remove heavy soiling.
ATTENTION
Not suitable for cleaning sensitive surfaces.
Illustration
 Attach the round brush to the detail nozzle.
Suited for all washable walls and floor coverings, e.g.
stone floors, tiles and PVC floors. Work slowly on very
dirty surfaces to allow the steam to act on the dirt for a
longer period of time.
Note
Detergent residue or care emulsions that are still pre-
sent on the surface to be cleaned can lead to streaks
during steam cleaning. However, these will disappear
with repeated cleaning procedures.
Illustration
 Attach the floor cloth to the floor nozzle.
1 Fold the floor cloth the long way and place the floor
nozzle on top of it.
2 Open holding clamps.
3 Place the cloth ends into the openings.
4 Close the holding clamps.

Care and maintenance

Rinse the boiler of the steam cleaner after completion of
the work.
 Fill the boiler with water and shake it strongly. This
dissolves lime scaling residing on the boiler bottom.
 Empty water out.
Descaling the boiler
As limescale builds up in the appliance, we recommend
to descale the appliance in the following intervals
(TF=tank fillings):
Note
In case of continuous use of commercially available dis-
tilled water, no descaling of the boiler is necessary.
Degree of hardness
I soft
II medium
III hard
IV very hard
Note
The hardness of the tap water can be inquired at your
water management office or the municipal utilities.
 Disconnect the mains plug from the socket.
 Allow device to cool down.
 Remove the safety lock from the device.
Illustration
 Completely empty the steam boiler to remove exist-
ing water.
 Use KÄRCHER decalcifying agents for descaling.
Please follow the dosing instructions on the pack-
aging when preparing the descaler.
ATTENTION
Use caution when filling and emptying the steam clean-
er. The descaling solution can have an aggressive ef-
fect on delicate surfaces.
 Pour the descaling solution into the boiler and allow
it to react for approximately 8 hours.
 Completely empty the descaling solution after 8
hours. A small amount of the solution will remain in
the boiler. Therefore, you should rinse the boiler
two to three times with cold water to remove any
residues of the descaler.

ing water.
