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
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.
"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 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.

 Pull the battery cable from the charger
cable and connect it to the machine.
Low maintenance batteries (wet batter-
ies)
 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.
Danger
Danger of chemical burns. Filling water in
while the battery is discharged can lead to
acid leaks!
Wear goggles when handling battery acid
and adhere to instructions to prevent inju-
ries and damage to clothing.
Flush any acid drops on the skin or clothes
immediately with plenty of water.
Caution
Use only distilled or desalinated water (EN
50272-T3) for filling the battery.
Do not add any substances (so-called per-
formance improving agents), else warranty
claims will not be entertained.
