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 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.
● 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
charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3
seconds (off for 0.3 seconds).
The battery will not be recharged. In such a case, let the battery cool before
charging.
● When the charge indicator lamp fl ickers (at 0.2-second intervals), check for and
take out any foreign objects in the charger's battery connector. If there are no
foreign objects, it is probable that the battery or charger is malfunctioning. Take it
to your authorized Service Center.
HOW TO RECHARGE USB DEVICE
WARNING
○ Prior to use, check the connecting USB cable for any defect or damage.
Using a defective or damaged USB cable can cause smoke emission or ignition.
○ When the product is not being used, cover the USB port with the rubber cover.
Buildup of dust etc. in the USB port can cause smoke emission or ignition.
NOTE
○ The time required for charging will be longer when a USB device and battery are being
simultaneously charged.
○ There may be an occasional pause during USB recharging.
○ When a USB device is not being charged, turn the USB power switch OFF and remove the
USB device from the charger.
Failure to do so may not only reduce the battery life of a USB device, but may also result in
unexpected accidents.
