Regarding the temperature 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.
䡬
Regarding recharging time
Table 4 shows the recharging time required
according to the type of battery.
Table 4 Recharging time (approx. min.) at 20°C
NOTE
The recharging time may vary according to the
ambient temperature and the power supply voltage.
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.
How to make the batteries perform longer.
䡬
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.
䡬
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.
