falls approximately below −10°C (14°F),
charging will automatically stop to pre-
vent degradation of the battery.
The ambient temperature range is be-
tween 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C (32°F),
the tool may fail to function properly.
When charging a cool battery pack (below
0°C (32°F)) in a warm place, leave the
battery pack at the place and wait for more
than one hour to warm up the battery to the
level of the ambient temperature.
Cool down the charger when charging
more than two battery packs consecu-
tively.

ately 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.

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.
