ATTENTION

Risk of damage. Ensure correct polarity.



Connect pole using the enclosed con-

necting cable. 



Connect the connection cable to the 

free battery poles (+) and (-).



Insert battery plug. 



Set the battery type (see Chapter "Grey 

Intelligent Key".

ATTENTION

Risk of damage due to full 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 - 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 (suitable for 

the batteries used) are regulated electroni-

cally and will automatically terminate 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").

Danger of explosion. The charging of wet 

batteries is only permitted if the waste wa-

ter reservoir is tilted up.

1 IEC connector for charging cable



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.

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 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.

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. 

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.

Note:

A "V" to the right of the bar of the battery in-

dicator shows that the initial charge has not 

been performed yet.

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.



Bring the safety switch into the "0" posi-

tion.
