Caution
Make sure that the power cable or exten-
sion cables are not damaged by running
over, pinching, dragging or similar. Pro-
tect the power cable from heat, oil, and
sharp edges.
Never fill solvents, solvent-containing liq-
uids or undiluted acids (e.g. detergents,
benzene, paint thinner, and acetone)
into the water reservoir as these sub-
stances affect the materials used on the
appliance.
The appliance must provide of a stable
ground.
Never operate or store the appliance in a
horizontal position!
The steam switch must not be locked
during the operation.
Protect the appliance from rain. Do not
store outside.
Safety elements
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.
Pressure controller
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.
Low-water thermostat
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.
Safety thermostat
If the boiler thermostat fails and the appli-
ance overheats, then the safety thermostat
turns off the appliance.
Please contact your local KÄRCHER cus-
tomer service to arrange for the reset of the
safety thermostat.
Safety lock
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.
