(2) Regarding the temperature of the rechargeable
battery.
The temperatures for rechargeable batteries are
as shown in Table 3, and batteries that have
become hot should be cooled for a while before
being recharged.

4. Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling
on the cord.
Make sure to grasp the plug when removing from
receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out
the battery from the battery charger.
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.

(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 2, according to the condition of the charger
or the rechargeable battery.
Table 2
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 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.
● If the battery is rechraged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
● When the pilot lamp flickers rapidly 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.
Malfunction in the battery
or the charger
Battery overheated.
Unable to charge
(Charging will commence
when battery cools).
