8.4 Commissioning the Charger
Mains Operation:
Connect the power supply plug to the charger. Connect the power supply to the
mains supply.
Charging the special Retsch storage batteries:
The charging starts automatically when one or more batteries are inserted.
To insert the storage batteries, it is first necessary to insert the charging adapter:
Press the contact bridge (5) down and insert the cell into the charging
compartment.
The storage batteries do not have to be inserted at the same time because the
batteries charge independently of each other.
It is normal for the batteries to become hot while charging. Once charging is
complete, the batteries are supplied with trickle charging and can remain in the
charger till they are used.
Discharging:
To discharge the storage batteries, simply press the PRESS button (4) for approx.
3 seconds. Once the storage batteries have finished discharging, the appliance
automatically switches over to charging. It is possible to discharge some batteries
and simultaneously charge other batteries. When batteries are inserted into
unoccupied charging compartments after activated discharging, they are charged
and not discharged!
8.5 Maintenance and Care of the Charger
Pull out the mains plug before doing any maintenance and cleaning work. To
ensure that the appliance will work without problems, please keep the contacts in
the charging compartment free of dirt. Clean the appliance only with a dry cloth.
