(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.

CAUTION
Do not use the electrical cord if damaged. Have it
repaired immediately.
2. Insert the battery into the charger.
Firmly insert the battery into the charger, as shown in
Fig. 7.
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 temperature
and power source voltage.
CAUTION
When the battery charger has been continuously 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.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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.
