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 discharged.
Make sure that the battery is charged before starting the
system.
Charging the battery
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 bat-
tery 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.
Only use the charger in dry rooms with sufficient ventila-
tion.
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 intensi-
ty.

Note
● The average charging time for wet batteries is approx.
10-12 hours.
● The average charging time of the Li-Ion batteries is ap-
prox. 3 hours.
The recommended chargers (for the respective batteries)
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 battery
plug and connect it to the charging cable.
b With Li-Ion battery variant: Connect the charger ca-
ble to the battery via the separate plug connection.
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
clothes
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
clothes using copious amounts of water.
ATTENTION
Using water with additives
Defective batteries, loss of warranty claim
Top up the batteries using only distilled or desalinated wa-
ter (EN 50272-T3).
Do not use any foreign additives, so-called enhancing
agents, because this will invalidate the warranty.
1. Add distilled water one hour before the charging pro-
cess 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 de-
scribed in the "Cleaning the batteries" section in the
Care and Maintenance chapter.
