Steam cleaning electric household 
appliances
If you use the appliance to clean electric 
household appliances (e.g. electric kitch-
en ranges) these appliances must be off 
circuit (switch off the fuse). Before you 
use the appliances again make sure they 
have dried completely. Please observe 
the notes of the appliance manufactur-
ers!
Caution: The device should not be used 
to clean electrical appliances such as ov-
en, exhaust, micro-wave, television, 
lamps, hair-dryer, electrical heating sys-
tems, etc.

nance works.

Storage
Caution: Never operate or store the ap-
pliance in a horizontal position!
Protect the unit from rain. Do not store 
outside.
This steam cleaner is equipped with several 
safety devices that provide an all-round pro-
tection of the appliance. The most important 
safety devices are described in the follow-
ing.
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.
When the water in the boiler becomes ex-
hausted, the temperature of the heating in-
creases. The low-water thermostat turns off 
the heating, and the red low-water indicator 
lamp lights up. The heating is prevented 
from being turned on again until the boiler 
has cooled down or refilled with water.
If the boiler thermostat fails and the appli-
ance overheats, then the safety thermostat 
turns off the appliance. 
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 customer 
service before you put the appliance into op-
eration again.
