4. Hold the charger firmly and pull out the battery.
NOTE:
After operation, pull out batteries from the charger
first, and then keep the batteries properly.
Regarding elect ric discharge in case of new
batteries, etc.
As the internal chem ical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge m ight
be low w hen using them the first and second tim e.
This is a tem porary phenom enon, and norm al tim e
required for recharging w ill be restored by recharging
the batteries 2 – 3 tim es.
How to make the batteries perform longer
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the pow er of the tool becom es
w eaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery m ay be dam aged and its life w ill
becom e shorter.
(2) Avoid recharging at high tem peratures.
A rechargeable battery w ill be hot im m ediately after
use. If such a battery is recharged im m ediately after
use, its internal chem ical substance w ill deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a w hile.
CAUTION:
When the battery charger has been continuously used,
the battery charger w ill be heated, thus constituting
the cause of the failures. Once the charging has been
com pleted, give 15 m inutes rest until the next
charging.
If the battery charger does not w ork w hile the battery
is m ounted correctly, it is probable that the battery or
