Operation
Starting Operation
 Observe the mains voltage! The voltage of the power
supply must correspond with the data given on the name-
plate of the battery charger. Battery chargers marked with
230 V can also be operated with 220 V.
Charging Procedure
The charging process begins as soon as the mains plug of the
charger is plugged into the socket outlet and the inductive
battery 1 or the power tool with battery 1 (with base of the
battery) is placed onto the charging platform 5.
The charging process only begins when the battery capacity is
less than 85 – 90 %. This prolongs the life of the battery.
Due to the intelligent charging method, the charging condi-
tion of the battery is automatically detected and the battery is
charged with the optimum charging current, depending on
battery temperature and voltage.
This gives longer life to the battery and always leaves it fully
charged when kept in the charger for storage.
Meaning of the Indication Elements
Continuous Light Standby Indicator (green) 2
The continuous light of the green standby indica-
tor 2 shows that the mains plug has been plugged

Working Advice
With continuous or several repetitive charging cycles without
interruption, the charger can warm up. This is not meaningful
and does not indicate a technical defect of the battery charg-
er.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.

The fast charging process is indicated by
the flashing of the respective green LED of
the charge status indicator 3. When the re-
