When charging is completed, an internal electronic switch will automatically be trig- gered to prevent overcharging.

Charging will not start if the battery pack is warm (for example, immediately after heavy-duty operation).

The orange standby lamp will be flashing until the battery cools down. Charging will then begin automatically.

4.When charging is completed, the charging lamp will start flashing quickly in green color.

5.If the charging lamp does not light imme- diately after the charger is plugged in, or if after the standard charging time the charg- ing lamp does not flash quickly in green, consult an authorized dealer.

6.If a fully charged battery pack is inserted into the charger again, the charging lamp lights up. After several minutes, the charg- ing lamp may flash quickly to indicate the charging is completed.
