○ 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 fi rst 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.
○ 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.
○ 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 charged while it is heated
because it has been left for a long time in a
location subject to direct sunlight or because the
battery has just been used, the pilot lamp of the
charger lights for 1 second, does not light for 0.5
seconds (off for 0.5 seconds).
The battery will not be recharged. In such a case,
let the battery cool before charging.
● When the pilot lamp fl ickers (at 0.2-second
intervals), check for and take out any foreign
objects in the charger's battery connector. If
there are no foreign objects, it is probable that
the battery or charger is malfunctioning. Take it
to your authorized Service Center.
