Use and store the unit only in accord-
ance with the specifications in the de-
scription and/or figure.
The steam switch must not be locked
during the operation.
Protect the appliance from rain. Do not
store outside.
Caution
Safety devices protect the user and must
not be modified or bypassed.
The pressure controller keeps the boiler
pressure during the operation as constant
as possible. The heating is turned off if the
maximum operating pressure of 4 bar is
reached in the boiler and is reactivated in
case of a pressure drop in the boiler due to
steam tapping.
The safety thermostat turns off the appli-
ance if the boiler thermostat and the pres-
sure controller fails and the appliance
overheats in case of a malfunction. Please
contact your local KÄRCHER customer
service to arrange for the reset of the safety
thermostat.
The safety lock seals the boiler against the
steam pressure that builds up in the boiler.
If the pressure controller is defect and the
steam pressure in the boiler rises, a pres-
sure control valve in the safety lock opens,
and steam is emitted through the lock to the
outside.
Please contact your local KÄRCHER cus-
tomer service before you put the appliance
into operation again.
