5. How to use the accessories

Wallpaper remover

The wallpaper remover is available as a special
accessory (see page 27 for the order number).
You can use the wallpaper remover with the
steam cleaner to remove wallpapers.
• Place the entire surface of the wallpaper
remover along the edge of a strip of wallpaper.
Switch on the steam supply (C4) and allow the
steam to act on the wallpaper until it is
completely soaked (approximately 10
seconds).
• Move the wallpaper remover to the next piece
of wallpaper you want to remove. Hold the
steam switch (C4) pressed while you move
the tool. Lift the soaked piece of wallpaper
using a flat trowel, and pull it off the wall. Move
the wallpaper remover from strip to strip, and
pull the wallpaper off in strips.
• In case of woodchip wallpaper that has been
painted several times, the steam may not be
able to soak the wallpaper. Thus, we
recommend to prepare the wallpaper using a
spiked roller before steam is applied.

Cleaning the boiler

Rinsing the boiler
If your tap water is harder than 10 degrees of
German hardness (=°dH), i.e. hardness class II,
rinse the boiler of the steam cleaner at the latest
after having filled it with water five times. If the
water is softer, you should rinse the boiler at the
latest after having it filled 15 times. Please
contact your Conservancy Board or the local
water supply company to inquire about the
hardness of your water.
• Fill the boiler with water and shake it
Descaling the boiler
As limescale also builds up on the boiler walls,
we recommend to descale the boiler in the
following intervals (TF=boiler fillings):

vigorously. This will loose any limescale that
has built up on the bottom of the boiler. Tilt the
appliance towards the edge with the funnel
inlet and pour the water out (see Figure 12).
