Maintenance And Care; Descaling The Boiler - Kärcher SC 1.020 Operating Instructions Manual

Steam gun
You can use the steam gun without any ad-
ditional accessories, e.g.:
to remove odours and wrinkles from
–
hanging clothes by steaming them at a
distance of 10 to 20 cm.
to remove dust from plants. Here, keep
–
a distance of 20-40 cm.
for moist dusting, by briefly steaming
–
the cloth and wiping the furniture with it.
Detail nozzle
The closer this nozzle is to the contaminat-
ed area, the higher the cleaning effect, as
the temperature and the steam are highest
at the nozzle output. Especially suited for
cleaning difficult access locations, joints,
fittings, drains, sinks, toilets, 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 sur-
faces.
 Illustration
Attach the round brush to the detail noz-
zle.
Hand nozzle
Pull the terry cloth cover over the hand noz-
zle. Especially well-suited for small washa-
ble areas, shower stalls and mirrors.
Floor nozzle
Suited for all washable walls and floor cov-
erings, 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 long-
er 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. 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.
Caution
Do not insert fingers between the clamps.
Parking the floor nozzle
 Illustration
During work breaks, hook the floor noz-
zle into the parking holder.

Maintenance and care

Danger
Always disconnect the mains plug and al-
low 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
strongly. This dissolves lime scaling re-
siding 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.
