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.
CAUTION
● When the battery charger has been continuosly
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). In such a case,
fi rst let the battery cool, then start 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 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.
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.
(1) Select a charging method
Depending on the charge method selected, either the
battery is inserted into the charger or the power cord
is plugged into an outlet.

(3) Connect the USB cable. (Fig. 8)
Pull back the rubber cover and fi rmly plug in a
commercially available USB cable (appropriate to the
device being charged) into the USB port.
○ When the power cord is not plugged into an outlet and
the battery runs out of power, power output will stop
and the USB power indicator lamp will shut off .
○ When the USB power indicator lamp goes out, change
the battery or plug the power cord into an electrical
outlet.
(4) When charging is completed
○ The USB power indicator lamp will not go out when a
USB device has been completely charged.
To verify charge status, check the USB device.
○ Turn the USB power switch OFF and unplug the power
cord from the electrical outlet. (Fig. 8)
○ Remove the battery from the charger and place the
rubber cover over the USB port.
<Pausing of charging of a USB device>
○ When plugging in the power of the charger during
charging from the battery to a USB device, or when
attaching the battery during charging from the
charger to a USB device, charging is paused for about
5 seconds as the power supply source is determined.
