Operating instructions

- 5
 Push the battery insert towards the
front.
 Lock in the battery insert lock.
 Set the battery type (see Chapter "Grey
Intelligent Key".
ATTENTION
Risk of damage due to total discharge.
Charge the batteries before commissioning
the appliance.
Note:
The appliance is equipped with a total dis-
charge protection, i.e. if the still admissible
minimum of the capacity is reached, the ap-
pliance can only be driven. The display
shows the message "Battery low - cleaning
not possible" and "Battery empty - please
charge".
 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 supply net-
work and fuse protection. Only use the
charger in dry rooms with sufficient ventila-
tion!
Note:
Average charging time is approx. 10 -12
hours.
The charger automatically switches off the
charging process.
 DANGER
Danger of explosion. The room, where the
machine is kept to charge the battery, must
feature a minimum volume and an air ex-
change with a minimum flow rate, depend-
ing on the type of battery (see "Recom-
mended Batteries").
Risk of explosion. Batteries may only be
charged while the battery cover is open.
 Open the lock of the battery cover.
 Tilt the battery cover backwards.
 Connect the power cable with the IEC
connector on the appliance.
 Connect the mains cable to the power
supply system.
A battery symbol and the state of
charge of the battery is shown on the
display. The display lighting goes out.
 Do not close the battery cover during
charging!
Note:
During the charging process all cleaning
and driving functions are blocked.
When the battery is fully charged, "Charg-
ing completed" is shown on the display.
 Pull the mains plug out of the socket
and unplug the cable from the appli-
ance after the charging process.
 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 causticization!
Adding water to the battery in its dis-
charged state can cause the acid to leak.
Use safety glasses while handling battery
acid and follow the safety instructions to
avoid personal injury or damage to clothes.
Should the acid spray on to the skin or
clothes, rinse immediately with lots of wa-
ter.
ATTENTION
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.
Battery compartment size: 546 mm x
391 mm
Note:
With the initial charge, the control will not
yet be able to detect which battery type has
been installed. In this case, the battery indi-
cator still works inaccurately.
A "V" to the right of the bar of the battery in-
dicator shows that the initial charge has not
been performed yet.
 Charge the battery until the display
shows the maximum charge condition.
 Use the appliance until the deep dis-
charge protection switches off the
brush motor and the turbine after the in-
itial charge of the batteries.
 Then correctly and completely charge
the batteries.
After the initial charge, the "V" to the right of
the battery indicator disappears.
Now the battery indicator works accurately.
Note:
If a battery type is selected in the battery
menu, the procedure described above
must be performed again. This is also the
case if the already set battery type is rese-
lected.
The charge condition of the batteries is
shown on the display of the control panel.
– The length of the bar indicates the
charge condition of the battery.
– During the last 30 minutes the remain-
ing operating time is indicated in min-
utes.
The procedure for changing the cleaning
head is described in the chapter "Mainte-
nance Tasks".
Note:
On some models, the cleaning head is al-
ready installed.
The installation of the brushes is described
in the chapter "Maintenance Tasks".
 Insert the vacuum bar into the vacuum
bar suspension in such a manner that
the profiled sheet is positioned above
the suspension.
 Tighten the wing nuts.
 Insert the suction hose.
Note:
Take the foot off the accelerator pedal and
press the emergency-stop pushbutton to
immediately switch off all functions.
 Plug in the Intelligent Key.
 Release emergency-stop button by
turning.
 Turn the programme switch to the de-
sired function.
 Wait until the device is ready for opera-
tion.
 Stand on platform and operate safety
switch.
 If the relevant indication appears on the
display, perform the maintenance task.
 Press Info button.
 Reset the counter for the corresponding
maintenance (see "Care and mainte-
nance/resetting counter").
Note:
If the counter is not reset, the maintenance
indicator appears again with every start-up
of the device.
