몇

Warning

Charge the batteries before commissioning
the machine.

Note

The device is equipped with a safety mech-
anism to prevent total discharge, i.e. when

the permissible minimum capacity is
reached, then the machine can only be driv-
en and existing lamps can be switched on.
In such a case, the battery monitoring sym-
bol on the control console glows red.

Drive the appliance directly to the
charging station; avoid any steep gradi-
ents in the process.

Note

While using other batteries (for e.g. batter-
ies from other manufacturers) the total dis-
charge protection level must be reset by the
Kärcher aftersales service according to the
respective battery.



Danger

Risk of electric shock. Observe supply net-
work and fuse protection - see "Charger".
Only use the charger in dry rooms with suf-
ficient ventilation!

Note

Average charging time is approx. 10 - 12
hours.
The recommended chargers (matching the
batteries used) are regulated electronically
and will automatically switch off the charg-
ing process.



Danger

Danger of explosion. Wet batteries can only
be charged with the seat tilted up.

Tilt the seat upward.

Take the power cord out of its holder
and insert the plug into the socket.
The display will show the charging sta-
tus of the batteries.

Note

All cleaning and drive functions are blocked
during the charging process. The functions
are blocked until a minimum of 90 minutes
has elapsed and the power plug has been
pulled.

After the charging process, pull the
power plug and insert into the holder on
the appliance.

Tilt the seat upward.

charging cable.

Connect the charger to the mains and
turn it on.

Switch off the charger and remove the
plug from the socket after you have fin-
ished charging.

Pull the battery cable from the charger
cable and connect it to the machine.

Add distilled water one hour prior to
charging; check correct acid level in the
battery. Batteries are marked accord-
ingly. At the end of the charging proc-
ess, all cells must gas.



Danger

Danger of chemical burns. Adding water to
the battery in its discharged state can cause
the acid to leak! Use safety glasses while
handling battery acid and follow the safety

instructions to avoid personal injury or dam-
age to clothes. Should the acid spray on to
the skin or clothes, rinse immediately with
lots of water.

몇

Warning

Risk of damage. Use only distilled or desal-
inated water (VDE 0510) for filling the bat-
tery. Do not add any substances (so-called
performance improving agents), else war-
ranty claims will not be entertained.
