Before Startup
Installing the Brushes
BD model
The disc brush must be installed before the
initial operation (see "Maintenance work").
BR model
The brushes are mounted.
Install batteries
Install the batteries (see "Care and Maintenance/Install and connect batteries").
Setting the charging marker line
Prior to the initial startup, following a service reset or when switching to another battery type, you must adjust the charging
marker line.
Use the Grey Intelligent Key.
Setting the charging marker line (see
Chapter "Grey Intelligent Key/Setting
the charging marker line“.
Using batteries made by other
manufacturers
We recommend using our batteries as described in chapter "Care and Maintenance/
Recommended batteries".
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 aftersales service.
Charging battery
Note:
The device is equipped with a safety mechanism to prevent total discharge, i.e. when
the permissible minimum capacity is
reached, the brush motor and the turbine
are switched off.
Drive the machine directly to the charg-
ing station; avoid any steep gradients in
the process.
DANGER
Danger of injury due to electric shock. Observe the mains voltage and fuse protection on the type plate of the device.
Only use the charger in dry rooms with sufficient ventilation!
Charging process
– Average charging time is approx. 10 -15
hours.
– The built-in charger has electronic con-
trols and is suitable for all recommended batteries; it automatically switches
off the charging process.
– The built-in battery is shown on the dis-
play during the charging process. If this
is not the case, the charging marker line
must be selected (see "Setting the
charging marker line").
– The appliance must not be used during
the charging process.
Insert the plug of the connecting cable
into the socket. The charging process
will start.
Note: The selected battery will be displayed during charging.
Charge until the display shows a full
charge.
Notes on initial charge
With the initial charge, the control will not
yet be able to detect which battery type has
been installed. Keep charging the batteries
until the display shows a full charge (batteries may still not be completely charged).
The next charging process will have an accurate display and charge power and the
batteries will be fully charged.
Use the appliance until the deep dis-
charge protection switches off the
brush motor and the turbine after the initial charge of the battery. This procedure is necessary to adjust the battery
indicator. Only then the correct battery
status is displayed.
Low maintenance batteries (wet
batteries)
몇 WARNING
Danger of causticization!
– Adding water to the battery in its dis-
charged state can cause the acid to
leak.
– Use safety glasses while handling bat-
tery 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
water.
ATTENTION
Risk of damage!
– Use only distilled or desalinated water
(EN 50272-T3) for filling the battery.
– Do not add any substances (so-called
performance improving agents), else
warranty claims will not be entertained.
– Replace batteries with the same battery
type only. Otherwise the charging char-
acterisitc must be readjusted by the af-
tersales service.
Installing the Vacuum Bar
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.
Check if the height adjustment is
mounted on the inside of the vacuum
bar.
When the height adjustment is mounted
on the outside, the vacuum bar gets
caught at the bottom of the appliance.
Unloading
DANGER
Risk of injury. Pull the Intelligent Key to take
all functions out of operation immediately.
Insert batteries and connect (see "Be-
fore Start-up").
Place long lateral boards of the packag-
ing as a ramp next to the pallet.
Fix the ramp on the pallet with nails.
