Caution:
Before decommissioning the machine for a longer
period, the batteries must run through a complete
charging cycle. The charger is then disconnected
from the machine and/or mains. Batteries gradually
discharge. Depending on the type of battery, they
must be recharged after 3-6 months.
- Before recommissioning, the batteries should run
through another complete charging cycle.
Charging procedure with external charger
Notice:
Only chargers recommended by the battery manu-
facturer and certified according to SELV (safety ex-
tra-low voltage) may be used.
Danger:
Do not plug the charger into the machine while it is
under tension (charger switched on).
The user may be injured by electric shock.
Warning:
Charging cables transfer high currents. Do not use
the charger if there are any signs of damage to the
plug, cable, or device connection.
• Connect the external battery charger with the battery
charging plug of the machine.
Notice:
Make sure that the plug is inserted up to the stop in
order to ensure a good electrical contact.
Notice:
Check whether the plugged-in charger has started
the charging process.
Notice:
If the charging process not started immediately, the
machine still switched on may be a reason for this.
You can see this at the flashing main switch.
The machine system will be shut down when the battery
charger is inserted. The charging process will not start
until the machine is switched off.
Notice:
All machine functions are deactivated during
charging.
Charging procedure with (optional) on-board
charger
• Take the power cord and connect it with a socket (with slow
fuse).
After charging
Warning:
Switch off the charger before disconnecting it from
the batteries.
Disconnecting the charger while it is still switched on
may cause an explosion in the battery compartment.
• Stow away the power cord for (optional) on-board chargers
in the provided compartment.

• Store the charging cable in a dry place where it is protected
against damage.
Maintenance and care of open (wet-cell) batter-
ies
Notice:
Caring for maintenance-free batteries only entails
following proper charging procedures and config-
uring the charging curve correctly.
Open battery compartment for maintenance
• The machine must be switched off.
Danger:
Before opening the battery compartment make sure
that both tank areas are empty.
• Disconnect the battery from the machine at the battery dis-
connection socket.
• Lower the suction nozzle.
• At the bottom left and right on the
front side of the machine you will find
the battery compartment release.
• Unscrew both screws and remove
them.
Variant: Machine with wet battery set
• At the bottom left on the front side of
the machine you will find the battery
compartment release.
• Press the release (e.g. with a screw-
driver) into the intended opening and
lift the tank until it locks.
• Tank position before change of posi-
tion.
• Stand behind the machine.
• Carefully open the battery compart-
ment until the driving handle is on the
ground.
Danger:
After maintenance, carefully tilt the tank back to its
initial position and lock it.
Notice:
Lift the suction nozzle again
