You can enter into a maintenance contract
with the concerned Kaercher Sales Office
for the machine.
The machine should be stored in frost-free
rooms. In case there is frosting risk, for e.g.
if the machine is installed in open areas,
then the machine must first be emptied and
flushed using an anti-freezing agent.
 Screw off water supply hose and high
pressure hose.
 Operate device for max. 1 minute until
the pump and conduits are empty.
Note
Observe handling instructions of the anti-
freeze agent manufacturer.

Fill in normal anti-frost agents in the
swimmer tank right until the top.
 Place the collection trough unter the
high pressure exit.
 Switch on the appliance and let it run
until the safety mechanism against lack
of water in swimmer tank gets activated
and the machine is switched off.
A certain corrosion protection is achieved
with this as well.
A Error number
B Number of currently present errors
– Error type 1: Emergency operation of
the system with remaining high pres-

pressure pumps are shut off.
– If one of the above errors occurs, the
appliance can be restarted after the er-
ror has been corrected by activating the
release switch.
Note
The 40 most recently occurred errors are
saved with the respective date and time and
can be shown on the display.
