3. During charging, the charging lamp will
be lit.
When charging is completed, an inter-
nal electronic switch will automatically
be triggered to prevent overcharging.
• Charging will not start if the battery
pack is warm (for example, immedi-
ately after heavy-duty operation).
The orange standby lamp will be
flashing until the battery cools down.
Charging will then begin automati-
cally.
. The charge lamp (green) will flash
slowly once the battery is approxi-
mately 80% charged.
5. When charging is completed, the
charging lamp in green color will turn
off.
6. If the temperature of the batter pack is
0°C or less, charging takes longer to
fully charge the battery pack than the
standard charging time.
Even when the battery is fully charged,
it will have approximately 50% of the
power of a fully charged battery at nor-
mal operating temperature.
7. Consult an authorized dealer if the
charging lamp (green) does not turn off.
8. If a fully charged battery pack is insert-
ed into the charger again, the charging
lamp lights up. After several minutes,
the charging lamp in green color will
turn off.
