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
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 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.
● If the battery charger does not work while
the battery is mounted correctly, it is
probable that the battery or charger is
malfunctioning. Take it to your authorized
Service Center.
