Kärcher SC 1.020 Instructions Abrégées page 17

Detail nozzle
The closer this nozzle is to the contaminated ar-
ea, the higher the cleaning effect, as the temper-
ature and the steam are highest at the nozzle
output. Especially suited for cleaning difficult ac-
cess locations, joints, fittings, drains, sinks, toi-
lets, blinds and heaters. Heavy lime scale can be
drenched in vinegar prior to steam-cleaning. 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.
Caution
Not suited for the cleaning of sensitive surfaces.

Illustration
Attach the round brush to the detail nozzle.
Hand nozzle
Pull the terry cloth cover over the hand nozzle.
Especially well-suited for small washable areas,
shower stalls and mirrors.
Floor 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 present on the surfaces to be cleaned,
can lead to smears when steam cleaned. How-
ever, these will disappear with repeated cleaning
procedures.

Maintenance and care
Danger
Always disconnect the mains plug and allow the
steam cleaner to cool down before performing
any maintenance work.
Rinsing the boiler
Rinse the steam cleaner boiler at the latest after
10 boiler fillings.

Fill the boiler with water and shake it strong-
ly. This dissolves lime scaling residing on the
boiler bottom.

Empty water out.
Descaling the boiler
Note: If you always use usual commercial distilled
water it is not necessary to descale the boiler.
As limescale builds up on the boiler walls, we
recommend to descale the boiler in the following
intervals (RF=reservoir fillings):
Degree of hardness
I soft
II medium
III hard
IV very hard
Note: Please contact your Conservancy Board
or the local water supply company to inquire
about the hardness of your water.

Disconnect the mains plug from the socket.

Allow device to cool down.

Remove the safety cap from the device.

Completely empty the steam boiler to re-
move existing water (see fig.
Warning
Only use products approved by KÄRCHER to
exclude any damages of the appliance.

User the KÄRCHER decalcifier sticks (order
no. 6.295-047) to decalcify the water. Please
follow the dosing instructions on the packag-
ing while using the decalcifying solution.
Caution
Use caution when filling and emptying the steam
cleaner. The descaling solution can have an ag-
gressive effect on delicate surfaces.

Pour the descaling solution into the boiler
and allow it to react for approximately 8
hours.
