Prior to the initial startup, following a ser-

vice reset or when switching to another bat-

tery 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“.

We recommend using our batteries as de-

scribed in chapter "Care and Maintenance/

Recommended batteries".

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 after sales service according to 

the respective 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 suf-

ficient ventilation!

Average charging time is approx. 10 -15 

hours.

The built-in charger has electronic controls 

and is suitable for all recommended batter-

ies; it automatically switches off the charg-

ing 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 ac-

curate 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 bat-

tery. This procedure is necessary to adjust 

the battery indicator. Only then the correct 

battery status is displayed.

Danger

Risk of explosion!

Prior to 

Charging low-maintenance bat-

teries

, the tank must be swivelled upwards 

(see chapter "Installing and connecting bat-

teries"). This will prevent the generation of 

dangerous gases during the charging pro-

cess 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 dis-

played during charging.



Charge until the display shows a full 

charge.

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 instruc-

tions 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 cus-

tomer service.



Insert the vacuum bar into the vacuum 

bar suspension in such a manner that 

the profiled sheet is positioned above 

the suspension.
