The following must be observed when fitting the wet bat-
teries:
● The maximum battery dimensions must be observed.
● The seat must be pivoted up when charging wet bat-
teries.
● The battery manufacturer's regulations must be ob-
served when charging wet batteries.
Installing and connecting batteries
The batteries are already installed in the Bp variant. If
you did not receive a Bp variant, the batteries were ret-
rofitted at the national company or at your trusted deal-
er. This may be for availability, time, cost, import,
service, transport or similar reasons to your advantage.
ATTENTION
Risk of damage to the control electronics!
The control electronics can be destroyed by reversing
the polarity of the battery connections.
Take care to ensure the correct polarity when connect-
ing the batteries.
1. Adjust the steering wheel position all the way for-
ward.
2. Pivot the seat forward.
3. Remove the seat stop screw.
4. Remove the plug of the seat contact switch and
push it back through the opening.

battery terminals that are still free. Route the cable
so that it cannot be pinched by the seat.
Note
The Li-ion battery is supplied with the plug connection
connected.
17. Only with Fleet variant: Install the cables.

WARNING
Danger to life from fire or explosion if batteries are
deeply discharged!
Incorrect charging of deeply discharged batteries can
cause a fire.
Do not start the device if the battery is deeply dis-
charged.
Make sure that the battery is charged before starting the
system.
Note
The device has deep discharge protection. I.e. with lead
acid batteries, the device can only be driven when the per-
mitted minimum capacity level is reached. "Battery empty-
please charge" appears in the display. Cleaning operation
is not restricted for devices with Li-Ion batteries.
When using other batteries (e.g. from other manufactur-
ers), the deep discharge protection for the respective
battery must be reset by Kärcher Customer Service.
DANGER
Danger of death from electric shock!
There is a danger of electrical shock if the charger is
used improperly
Adhere to the mains voltage and fuse values specified
on the device type plate.
Height
Only use the charger in dry rooms with sufficient venti-
537 mm
lation.
Danger of explosion when charging the battery!
Flammable gases are generated when the battery is
charged
Only charge the batteries in a suitable room. The room
must have a minimum volume depending on the battery
type and an adequate air exchange rate with a minimum
air flow (see "Recommended batteries").
Only charge wet batteries with the seat pivoted up.
Note
If the device has a Li-ion battery, it is the battery that
switches off when the charge level is too low, not the de-
vice. From a charge level of <15%, <10% and <5%, the
system also emits acoustic signals with increasing in-
tensity.
Note
● The average charging time for wet batteries is ap-
prox. 10-12 hours.
● The average charging time of the Li-Ion batteries is
approx. 3 hours.
The recommended chargers (for the respective batter-
ies) are electronically controlled and end the charging
process automatically.
The device cannot be used during the charging process.
1. Drive the device directly to the charger and do not
drive on slopes.
2. Pivot the seat upwards.
3. Connect the charging cable to the battery.
a With lead battery variant: Disconnect the bat-
tery plug and connect it to the charging cable.
b With Li-Ion battery variant: Connect the charg-
er cable to the battery via the separate plug con-
nection.
4. Connect the charger to the mains and switch it on.
After the charging process
1. Lead battery:
a Switch off the charger and disconnect it from the
mains.
b Disconnect the battery cable from the charging
cable and connect it to the device.
Note
Route the charging cable in the battery compartment so
that it cannot be pinched.
2. Li-Ion battery:
a Disconnect the plug connector for the charger.
Note
The connector from the Li-ion battery to the device re-
mains connected during charging.
Low-maintenance batteries (wet batteries)
DANGER
Refilling discharged batteries with water
Danger of acid burns from escaping acid, destruction of
clothing
Wear safety goggles, protective clothing and protective
gloves when handling the battery acid.
Observe the applicable regulations.
Immediately rinse off any splashed acid from the skin or
clothing using copious amounts of water.
ATTENTION
Using water with additives
Defective batteries, loss of warranty eligibility
Top up the batteries using only distilled or desalinated
water (EN 50272-T3).
Do not use any foreign additives, so-called enhancing
agents, because this will invalidate the warranty.
Charging the battery
English
1. Add distilled water one hour before the charging
process comes to an end. Observe the correct acid
level according to the battery label.
All cells must produce gas at the end of the charging
process.
2. Clean up any spilled water. To do this, proceed as
described in the Care and maintenance chapter in
the "Cleaning the batteries" section.
Battery indicator
Wet battery variant:
The charging state of the batteries is shown on the con-
trol panel display.
● The length of the bar shows the battery charging
state.
Li-Ion battery variant:
The battery charging level is displayed on a separate
screen of the battery system.
● The percentage SoC (State of Charge) indicates the
charge state.
