Battery charger
1. Plug the charger into the AC outlet.
2. Insert the battery pack firmly into the
charger.
1. Line up the alignment marks and
place the battery onto the dock on
the charger.
2. Slide forward in the direction of the
arrow.
3. During charging, the charging lamp
will be lit.
When charging is completed, an
internal electronic switch will
automatically be triggered 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. The charge lamp (green) will flash
slowly once the battery is
approximately 80% charged.
5 When charging is completed, the
charging lamp in green color will
turn off.
6. If the temperature of the battery 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
normal operating temperature.
7. Consult an authorized dealer if the
charging lamp (green) does not turn
off.
8. If a fully charged battery pack is
inserted into the charger again, the
charging lamp lights up. After
several minutes, the charging lamp
in green color will turn off.
