Operation
Switch on the power supply for the charging unit. The charging unit starts with a system test, the fan test
and conrms this with a beep.
Before you can operate the charging unit, some pre-settings must be made.
The loader is operated via a dial with touch function (6). The menu items are selected by turning the dial.
Conrmation of the selection is done by pressing the dial. This procedure applies to all settings (system
settings and task settings).
The setting menus are largely self-explanatory and can be set easily using predened parameters.
a) Main display
The main display shows the basic parameters of the connected battery pack (current, capacity, battery
voltage and the individual cell voltages).
If the dial is turned down, additional parameters appear (input voltage, output voltage, system temperature,
charged energy in Wh, number of discharged batteries, number of charged batteries).
b) System settings
General settings needed to operate the charging unit are found in the system menu. To enter the system
menu, press the dial for approx. 2 seconds. The system menu will be displayed along with a beep.
First set the system language via the menu item „Language“. Turn the dial until the selection bar shows the
menu item. Press the dial to conrm. The menu item will open. The languages English, German, French or
Spanish can be selected.
Continue with the selection of parameters given. Follow the menu selection.
To exit the system menu, select the last menu item „← Zurück“ (Back) and press the dial.
c) Task settings
All parameters for battery maintenance are set in the task menu. To enter the task menu, press the dial for
approx. <1 seconds. The task menu will be displayed along with a beep (if the beep in the system menu has
not been deactivated).
Follow the menu selection. Start with the rst menu item and then select all other menu items.
Once all parameters are set and the battery connected, the selected task can be started by selecting
„►Aufgabe starten“ (start task) via the menu item.
To exit the task menu, select the last menu item „← Zurück“ (Back) and press the dial.
Make sure that the set parameters match the connected battery. If the charger is not properly congured,
the battery and charging unit may be damaged. It may cause a re or an explosion owing to overcharging.
Very carefully tend to the conguration. It is important to note the data in the following table if there are no
exact battery parameters.

Troubleshooting
The charging unit is very user-friendly thanks to the menu guidance and the plain text displays. Nevertheless,
a few problems may occur which we show you here and offer possible solutions.
Make sure all the settings made to the charging unit exactly match the connected battery!
Check for problems with the connection between the power supply and the charging unit (cuts or other
damage in the cable). Furthermore, check whether the plugs of the charging cable are in order and not too
small. Hot cables are usually an indication of this. The charging cable should never be longer than 30 cm and
have at least a conductor diameter of 2.5 mm².
When operating with a car battery, check that the connectors to the battery terminals make good contact.
Many charging unit problems arise from problems with the connection cables and terminals.
When trying to charge a different battery, the battery could be in poor condition which could cause problems
Try to charge a different type of battery. For example, change to a NiMH battery if you experience problems
with lithium cells. If there are also problems with other types of batteries, the charger may be defective.
Nevertheless, check everything very carefully again.
Contact our service department, give full details and describe the problem, including type of power supply,
battery and the number of cells.
If connection problems are indicated, make sure all battery connections are properly secured. Most im-
portantly, check the balancer connection. If everything is in order, clean the contacts on the connectors to
remove oxidation. Use an efcient switched-mode power supply or a fully charged car battery with a high
capacitance value. Try to charge another lithium battery from another manufacturer, preferably with a diffe-
rent balancer connector system to eliminate any possibility of error.
Never open the device, it is too dangerous and the warranty will be void! The charging unit must only be
repaired by qualied technicians. Improper repairs can lead to res and/or electric shocks. For repairs, send
the charger to our service department.
Disposal
a) General information
The product must not be disposed of in the household waste.
Dispose of the product at the end of its serviceable life in accordance with the current statutory
requirements; e.g., return it to any suitable collection point.
Remove any normal or rechargeable batteries inserted and dispose of them separately from the product.
b) Disposal of spent rechargeable batteries
As the end user, you are required by law (Battery Ordinance) to return all spent rechargeable batteries;
disposal of them in the household waste is prohibited!
Contaminated rechargeable batteries are labelled with these symbols to indicate that disposal in
the domestic waste is forbidden.
The symbols of the critical heavy metals are: Cd = Cadmium, Hg = Mercury, Pb = Lead.
You can return used rechargeable batteries free of charge, to any collection facility in your local
authority, to our stores or to any other store where rechargeable batteries are sold.
You thereby full your statutory obligations and contribute to the protection of the environment!
