⅜ 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.
⅜ 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:
ⅷ 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.
ⅷ If the battery is recharged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may not light.
The battery will not be recharged. In such a case, let the battery cool before charging.
