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

(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

NOTE:
The charging time may vary according to 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 electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.
CAUTION:
When the battery charger has been continuosly used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
If the battery is recharged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
map light in green.
The battery will not be recharged. In such a case, let
the battery cool before charging.
When the pilot lamp flickers in red (at 0.2-second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery or
charger is malfunctioning. Take it to your authorized
Service Center.

1. Connect the charger's power cord to the receptacle.
When connecting the plug of the charger to a
receptacle, the pilot lamp will blink in red
(At 1-second intervals).
2. Insert the battery into the charger.
Firmly insert the battery into the charger as shown
in Fig. 5, 6.
3. Charging
When inserting a battery in the charger, the pilot
lamp will light up continuously in red.
When the battery becomes fully recharged, the
pilot lamp will blink in red (At 1-second intervals).
(See Table 4)
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 4, according to the condition of the charger
or the rechargeable battery.
Battery overheated.
Unable to charge.
