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

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.
NOTE
Be sure to pull out the battery from the battery
charger after use, and then keep it.
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
(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
the
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.
