. CHARGING THE
BATTERY
NOTE
When you charge the battery pack
for the first time, or after prolonged
storage, charge it for about 24 hours
to bring the battery up to full capacity.
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. Insert the battery pack firmly into
the charger.

3. During charging, the charging lamp
will be lit.
When charging is completed, an
internal electronic switch will au
-
tomatically 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
lit until the battery cools down.
Charging will then begin automati
-
cally.
4. When charging is completed, the
charging lamp will start flashing
quickly in green color.
5. When in any of the conditions that
battery pack is too cool, or the bat
-
tery pack has not been used for a
long time, the charging lamp is lit. In
this case, charging takes longer to
fully charge the battery pack, than
the standard charging time.
If a fully charged battery pack is
inserted into the charger again,
the charging lamp light up. After
several minutes, the charging
lamp may flash quickly to indicate
the charging is completed.
6. If the charging lamp does not light
immediately after the charger is
plugged in, or if after the standard
charging time the lamp does not go
off, consult an authorized dealer.
NOTE:
When charging a cool battery
pack (below 5°C (41°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.
Otherwise battery pack may not be
fully charged.
Cool down the charger when
charging more than two battery
packs consecutively.
Do not insert your fingers into con-
tact hole, when holding charger or
any other occasions.
CAUTION:
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.
