5. How to use the accessories
5.7 Wallpaper remover
The wallpaper remover is available as
a special accessory - see page 12
• Place the entire face of the wallpaper remo-
ver along the edge of a sheet of wallpaper.
Switch on the steam supply (C3) and allow
the steam to penetrate the wallpaper until it
is soaked through (approx. 10 seconds).
• Move the wallpaper remover to the next sec-
tion to be removed, keeping the steam switch
(C3) pressed. Use a putty knife to lift the loo-
sened wallpaper and pull it off the wall. Move
the wallpaper across the wall a section at a
time and pull the paper off in strips.
• The steam may not be able to readily pene-
trate woodchip wallpaper that has been
painted over several times. In this case we
recommend that you go over the wallpaper
with a spiked roller before steam is applied.
5.8 Steam-rotary nozzle
The rotary nozzle is available as a
special accessory - see page 12
• The rotary nozzle can be attached directly or
with the extension tubes to the steam hand-
gun, as required.
• Use the rotary nozzle for loosening stubborn
dirt over large areas.
6. Maintenance
6.1 Cleaning the boiler
Note: If you always use demineralised or distil-
led water, it will not be necessary to clean the
boiler.
Rinsing out the boiler:
Rinse out the steam generator at most after
every 5th fill-up if the hardness of water pro-
ves to be more than 1.8 mmol/l (corresponds
to 10° dH). You can enquire about the hard-
ness of water in your area from your water
supply company or municipal public works.
• Fill the boiler with water and shake the clea-
ner vigorously. This will loosen any scale that
has settled at the bottom of the boiler. Tilt the
cleaner towards the corner with the funnel in-
let (A3) and pour out the water.
Descaling the boiler:
As scale also builds up on the walls of the boi-
ler, we recommend that you descale your
steam cleaner at the following intervals.
Remove lime-scale deposits after the given
number of tank fillings (TF).

• Unplug the cleaner from the mains electrici-
ty supply before you descale the boiler.
• Make sure that all traces of water are drai-
ned from the boiler.
• We recommend you use Kärcher Biological
Decalcifier RM 511 to descale the boiler.
This biological decalcifying agent is based
on citric acid and is therefore entirely biolo-
gically degradable.
