4.
Disconnect the charger's power cord from the receptacle.
5.
Hold the charger fi rmly and pull out the battery.
NOTE
After operation, pull out batteries from the charger fi rst, and then keep the batteries
properly.
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 battery has just been used, the
pilot lamp of the charger lights up green. In such a case, fi rst let the battery cool,
then start charging.
When the pilot lamp fl ickers in red (at 0.2–second intervals), check for and take out
○
any foreign objects in the charger's battery installation hole. If there are no foreign
objects, it is probable that the battery or charger is malfunctioning. Take it to your
authorized Service Center.
Since the built-in micro computer takes about 3 seconds to confi rm that the battery
○
being charged with the charger is taken out, wait for a minimum of 3 seconds
before reinserting it to continue charging. If the battery is reinserted within 3
seconds, the battery may not be properly charged.
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
(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.
