Charge the batteries before commissioning
the appliance.
Charge the batteries
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
driven and existing lamps can be switched
on. In such a case, the battery monitoring
symbol on the control console glows red.
 Drive the appliance directly to the
charging station; avoid any steep gradi-
ents in the process.
Note:
When using other batteries (e.g. batteries
from other manufacturers), the total dis-
charge protection level for the respective
battery must be reset by the Kärcher after-
sales service.
DANGER
Risk of electric shock. Observe power sup-
ply net and fuse protection – see "Charger".
Use the charger in dry rooms with sufficient
ventilation only!
Note:
Average charging time is approx. 10 -12
hours.
The recommended chargers (suitable for
the batteries used) are regulated electroni-
cally and will automatically terminate the
charging process.
DANGER
Danger of explosion. Wet batteries may
only be charged with the seat tilted up.
"Pack" model
 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 driving functions are
blocked during the charging process. The
functions are disabled until a charging peri-
od of at least 90 minutes has elapsed and
the mains plug has been unplugged again.
 After the charging process, pull the
power plug and insert into the holder on
the appliance.
Model without integrated charger
 Tilt the seat upward.
 Remove battery plug and join it to the
charging cable.
 Connect the charger to the mains and

240 Ah  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.
Low maintenance batteries (wet
batteries)
 Add distilled water one hour before the
charging process comes to an end; fol-
low the correct acid level. There are
corresponding indicators on the battery.
At the end of the charging process, all
cells must gas.
WARNING
Danger of causticization!
– Adding water to the battery in its dis-
charged state can cause the acid to
leak.
– Use safety glasses while handling bat-
tery acid and follow the safety instruc-
tions to avoid personal injury or damage
to clothes.
– Should the acid spray on to the skin or
clothes, rinse immediately with lots of
water.
ATTENTION
Risk of damage!
– Use only distilled or desalinated water
(EN 50272-T3) for filling the battery.
– Do not add any substances (so-called
performance improving agents), else
warranty claims will not be entertained.
