(2) Regarding the temperatures of the rechargeable
battery.
The temperatures for rechargeable batteries are as
shown in the table 2, and batteries that have become
hot should be cooled for a while before being
recharged.

2. Insert the battery into the charger
Insert the battery into the charger as shown in Fig.
3. Make sure the battery is fully seated in the
charger.
3. Charging
When inserting a battery in the charger, charging
will commence and the pilot lamp will light
continuously in red.
When the battery becomes fully recharged, the pilot
lamp will blink in red (At 1-second intervals.) (See
Table 1).
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 1, according to the condition of the charger
or the rechargeable battery.
NOTE: The charging time may vary according to ambient
temperature and power source voltage.
4. Disconnect the charger's power cord from the
receptacle
5. Hold the charger firmly and pull out the battery
NOTE
After operation, pull out batteries from the charger
first, and then keep the batteries properly.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
Malfunction in the
battery or the charger
The battery temperature
is high, making
recharging impossible.
