[Battery Charger]
Charging
CAUTION:
• If the temperature of the battery pack falls
approximately below -10 °C (14 °F), charging
will automatically stop to prevent degradation
of the battery.
• The ambient temperature range is between
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 consecutively.
• Do not insert your fingers into contact hole,
when holding charger or any other occasions.
To prevent the risk of fire or damage to the
battery charger.
• Do not use power source from an engine
generator.
• Do not cover vent holes on the charger and
the battery pack.
• Unplug the charger when not in use.
NOTE:
Your battery pack is not fully charged at the
time of purchase. Be sure to charge the battery
before use.
How to charge
1. Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the plug is
inserted into the AC power supply, but this is
not a problem in terms of safety.
2. Connect the battery pack firmly into the
charger.
3. During charging, the charging lamp will be
illuminated. 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 connected
into the charger again, the charging lamp
lights up. After several minutes, the charging
lamp in green color will turn off.
