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 will start flashing quickly
in green color.
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. If the power lamp does not light
immediately after the charger is plugged
in, or if after the standard charging time
the charging lamp does not flash quickly
in green, consult an authorized dealer.
8. If a fully charged battery pack is
inserted into the charger again, the
charging lamp lights up. After several
minutes, the charging lamp may flash
quickly to indicate the charging is
completed.
