CHARGER INDICATORS, SYMBOLS AND MEANING (Model BC660)
If the indicator lights are "OFF", the charger is
not receiving power from power supply outlet.
I _=]lf the green indicator light is
"ON", the charger is plugged
in but the battery pack is not
inserted, or the battery pack is fully charged, or
the battery pack is too hot or cold for fast-
charging. The charger will automatically switch
to fast-charging once a suitable temperature is
reached.
I _] If the green indicator light is
...... BLINKING", the battery pack is
being fast-charged. Fast-
charging will automatically stop when the
battery pack is fully charged.
CHARGING BATTERY
Plug charger cord into your standard power
outlet.
With no battery pack inserted, the charger's
green indicator light will go ON. This indicates
the charger is receiving power and the charger
is ready for operation.
When you insert the battery pack into the
charger, the charger's green indicator light will
begin to "BLINK". This indicates that the battery
is receiving a fast charge (Fig. 10).
When the indicator light stops "BLINKING" (and
becomes a steady green light) fast charging is
complete. The battery pack is fully charged and
can be removed from the charger.
When you begin the charging process of the
battery pack, a steady green light could also
mean the battery pack is too hot or too cold.
Fast charging is only possible when the
temperature range of the battery pack is
between 32°F (0°C) and 113°F (45°C). When
needed, the internal fan of the charger will turn
on to aid the charging process and speed.
PACK (Model BC660)
As soon as the battery pack reaches the
correct temperature range, the battery charger
will automatically switch to fast charging.
The battery pack may be used even though the
light may still be blinking. The light may require
more time to stop blinking depending on
temperature.
The purpose of the green light is to indicate that
the battery pack is fast-charging. It does not
indicate the exact point of full charge. The light
will stop blinking in less time if the battery pack
was not completely discharged.
If the green indicator light is "ON", the battery
pack cannot accept a charge.
• Check to make sure the battery pack is
inserted into the charger properly.
• Clean the contacts of the charger or battery
pack (e. g. by inserting and removing the
battery several times) or replace the battery
pack, as required.
When the battery pack is fully charged, unplug
the charger (unless you're charging another
battery pack) and slip the battery pack back into
the tool.
