extremely short after recharging, replace
the battery pack with a new one.

conditions will reduce operating
capacity per charge.

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, immedi-
ately 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 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

charged.

ing 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.
This can damage the charger and
present the risk of fire or personal
injury.
• Do not cover vent holes on the
charger and the battery pack.
