When charging is completed, an internal elec-
tronic 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 lit until the
battery cools down. Charging will then begin
automatically.
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 battery 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
lights up. After several minutes, the charg-
ing 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, con-
sult 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 contact hole,
when holding charger or any other occasions.
CAUTION:
To prevent damage or risk of fire:
• Do not use power source from an engine gen-
erator.
• Do not cover vent holes on the charger and the
battery pack.
• Unplug the charger when not in use.
