(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in the table below, 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 5.

(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 3, according to the condition of the charger
or the rechargeable battery.
NOTE
Be sure to pull out the battery from the 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 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
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 batetery has just
been used, the pilot lamp of the charger lights up
green. In such a case, first let the battery cool, then
start charging.
Malfunction in the
battery or the charger
The battery tempera-
ture is high, making
recharging impossible
