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
While using other batteries (for e.g. batteries from other manufacturers) the total discharge protection level must be reset by
the Kärcher after sales service according to
the respective battery.
Charging battery
Note
The appliance 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
Risk of injury on account of electric shock.
The mains voltage must correspond with
the type plate on the appliance.
Use the charger only in dry rooms with sufficient ventilation!
Charging process
Average charging time is approx. 10 -15
hours.
The built-in charger has electronic controls
and is suitable for all recommended batteries; it automatically switches off the charging process.
The built-in battery is shown on the display dur-
ing 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.
Initial charge tips
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 (batter-
ies 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 discharge
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.
몇 Danger
Risk of explosion!
Prior to Charging low-maintenance bat-
teries, the tank must be swivelled upwards
(see chapter "Installing and connecting batteries"). This will prevent the generation of
dangerous gases during the charging process under the tank.
While the water tank is folded up, you must
not clean with any water.
When charging maintenance-free batter-
ies, the water tank does not need to be
folded up.
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.
Low maintenance batteries (wet batteries)
몇 Warning
Danger of causticization!
– Adding water to the battery in its discharged
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.
Caution
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 only with batteries of
the same type. Otherwise, the charging
guideline must be readjusted by customer 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.
