As limes cale builds up on the boiler walls,
we recommend to de scale the boiler in the
following intervals (RF = reservoir fillings):
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 the steam cleaner to cool down.
 Empty the water reservoir or remove it
from the appliance.
 Remove the accessories from the ac-
cessory compartments.
Illustration

Open the locking door of the accessory
compartment.
 Remove the accessories from the ac-
cessory compartment.
 Open the maintenance lock. For this,
place the open end of an extension pipe
onto the maintenance lock, lock it into
the guide and unscrew it.
 Completely empty the steam boiler to
remove existing water (see fig. ).
ṇ
Warning
Only use products approved by KÄRCHER
to exclude any damages of the appliance.

Use the KÄRCHER decalcifier sticks
(order no. 6.295-206) to decalcify the
water. Please follow the dosing instruc-
tions on the packaging while using the
decalcifying solution.
ṇ
Caution
Use caution when filling and emptying the
steam cleaner. The descaling solution can
have an aggressive effect on delicate sur-
faces.

Pour the descaling solution into the boil-
er and allow it to react for approximately
8 hours.
ṇ
Warning
Do not screw the maintenance lock onto
the appliance during the decalcifying.
Do not use the steam cleaner as long as
there is decalcifying agent in the boiler.

Completely empty the descaling solu-
tion after 8 hours. A small amount of the
solution will remain in the boiler. There-
fore, you should rinse the boiler two to
three times with cold water to remove
any residues of the descaler.
 Completely empty the steam boiler to
remove existing water (see fig. ).
 Screw the maintenance lock in using
the extension pipe.
 Fill water reservoir (see page 8).
 The steam cleaner is ready to use.
Note: The floorcloth and the terry cloth cov-
er have been pre-washed and can be used
immediately for working with the steam
cleaner.

You can wash dirty floorcloths and terry
cloth covers in the washing machine at
60°C. Do not use a liquid softener as
this would affect the ability of the cloths
to pick up dirt. You may tumble dry the
cloths.
Often, failures have simple causes and you
can do the troubleshooting yourself using
