BATTERY REMOVAL/INSTALLATION

1. Battery removal
Hold the handle tightly and push the battery release
buttons (2 pcs.) to remove the battery (see Figs. 1 and
2).
CAUTION:
Never short-circuit the battery.
2. Battery installation
Insert the battery while observing its polarities (see
Fig. 2).
CHARGING
Before using the driver drill, charge the battery as follows.
1. Connect the charger's power cord to a receptacle.
2. Insert the battery into the charger.
Firmly insert the battery into the charger till it contacts
the bottom of the charger and checking the polarities
as shown in Fig. 3.
Inserting the battery will turn on the charger (the
pilot lamp lights up).
CAUTION
If the pilot lamp does not light up, pull out the
power cord from the receptacle and check the
battery mounting condition.
The pilot lamp goes off to indicate that the battery is
fully charged.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just after operation, the charger pilot lamp may
not light. At that time cool the battery first, then
start charging.
Regarding recharging time
Table 1 shows the recharging time required according
to the type of battery.

NOTE: The recharging time may vary according to the
ambient temperature.
3. Disconnect the charger's power cord from the
receptacle.
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 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 first 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.
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 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.

PRIOR TO OPERATION

1. Setting up and checking the work environment
