Installing and connecting batteries
Note
In the case of the device variant with Li-Ion battery, the
battery is already installed and connected. A Li-Ion bat-
tery may only be installed or replaced by the customer
service.
DANGER
Danger of fire and explosion!
Do not place tools or similar items on the battery. Risk
of short-circuit and explosion.
Smoking and naked flames must be strictly avoided.
Rooms where batteries are charged must have good
ventilation as highly explosive gas is emitted during
charging.
CAUTION
Removing and installing the batteries
Unstable machine position
Ensure that the machine is positioned stably when re-
moving and installing the batteries.
ATTENTION
Incorrect connection polarity
Destruction of the control electronics
Take care to ensure the correct polarity when connect-
ing the batteries.
ATTENTION
Deep discharge
Risk of damage
Charge the batteries before starting the device.
1. Push the device approx. 2 m forwards so that the
steering rollers point to the rear.
2. Hold the waste water tank by the recessed grip and
pivot it sideways and upwards.
3. Fit the batteries in the pan.
4. Connect the batteries:
a Fit the spacers.

Setting the charging characteristic
Before the initial startup, after a service reset or when
changing to a different battery type, it is essential to set
the charging characteristic.
DANGER
Danger due to the device inadvertently starting up
Risk of injury
Disconnect the spark plug connector or disconnect the
battery before performing any work on the device.
ATTENTION
Risk of damage to the battery
The service life and charging capacity of the battery can
be affected by an incorrect charging characteristic.
Make sure that the battery characteristic curve that
matches the battery is selected in the machine.
The currently selected battery characteristic curve can
be seen on the display or via the app in the "Device sta-
tus" area during charging.
Note
The charging characteristic can only be adjusted by
Kärcher Service.
Battery characteristics are available for the following
batteries:
● EXIDE GF12105V
● HOPPECKE TB115
● EXIDE GF12076V
● EXIDE FF12080W
● TROJAN 27TMX
● HOPPECKE TB80
● ZENITH L120185
Note
To enable the use of other batteries as well, a custom
battery characteristic curve can be created by the
Kärcher service department.
DANGER
Inappropriate use of the charger
Electric shock
Adhere to the mains voltage and fuse values specified
on the device type plate.
Only use the charger in dry rooms with sufficient venti-
lation.
The built-in charger is electronically controlled and suit-
able for all recommended batteries, it ends the charging
process automatically.
Note
The corresponding charging characteristic must be set
for each type of battery installed.
The installed battery is shown in the display when
charging.
The average charging time is approx. 10-15 hours.
The device cannot be used during the charging pro-
cess.
Note
The device has deep discharge protection, i.e. the
brush motor and turbine are switched off automatically
in operation when the permitted minimum capacity level
is reached.
1. Drive the device directly to the charger and do not
drive on slopes.
2. Plug the mains plug on the power cable into the
mains socket.
3. Charge until the display shows full charge.
