1. Line up the alignment marks and
place the battery onto the dock on
the charger.
2. Slide forward in the direction of the

3. During charging, the charging lamp
will be lit.
When charging is completed, an in-
ternal electronic switch will auto-
matically be triggered to prevent
overcharging.
• Charging will not start if the battery
pack is warm (for example, imme-
diately after heavy-duty operation).
The orange standby lamp will be
flashing until the battery cools
down.
Charging will then begin automat-
ically.

slowly once the battery is approxi-
mately 80% charged.

ing lamp in green color will turn off.

will have approximately 50% of the
power of a fully charged battery at nor-
mal operating temperature.

charging lamp (green) does not turn
off.

serted into the charger again, the
