APPLICATIONS
○ Driving and removing of machine screws, wood screws,
tapping screws, etc.
○ Drilling of various metals.
○ Drilling of various woods.
BATTERY REMOVAL/INSTALLATION
1. Battery removal
Hold the handle tightly and push the battery latch 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 power cord to the receptacle
Connecting the power cord will turn on the charger.
2. Insert the battery into the charger
Insert the battery fi rmly while observing its direction,
until it contacts the bottom of the charger (See
Fig. 3)
(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.
(1) Regarding the temperatures of the rechargeable battery
The temperatures for rechargeable batteries are as
shown in Table 1.
Table 1 Recharging ranges of batteries
Rechargeable batteries
Tem pe rat ures at
which the battery
can be recharged
BCC1212 0°C – 40°C
(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 2.

Battery
UC18YK
BCC1212 Approx. 50 min.
The pilot lamp goes off to indicate that the battery is
fully charged.
The battery charging time becomes longer when a
temperature is low or the voltage of the power source is
too low.
CAUTION
If the battery is heated due to direct sunlight, etc.,
just
after operation, the charger pilot lamp may not
light up. At that time, cool the battery fi rst, then start
charging.
3. Disconnect the charger’s power cord from the
receptacle
4. Hold the charger fi rmly and pull out the battery
NOTE
After charging, pull out batteries from the charger fi rst,
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 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.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by following
the precautions.
