BATTERY REMOVAL/INSTALLATION

1. Battery removal
Hold the handle tightly and push the battery latch (1 pc.
or 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
<UC9SD/UC12SD>
Before using the driver drill, charge the battery as follows.
1. 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).
CAUTION
The UC9SD and UC12SD models are the exclusively
designed charger. These cannot charge batteries
except the specifi ed batteries. It is possible to insert
the batteries other than the specifi ed into the charger
and some of them may light up the pilot lamps.
However, you are requested to exercise utmost
caution not to charge batteries other than specifi ed
ones because these can not only be charged but
also such actions can result in the malfunction of
chargers.
2. Connect the charger power cord to the receptacle.
Connecting the power cord 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.
About 60 minutes are required to fully charge the battery
at a temperature of about 20°C. 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.
When the pilot lamp does not go off even if more than 120
minutes have elapsed after starting of the charging, stop
the charging and contact your HITACHI AUTHORIZED
SERVICE CENTER.

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 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.
<UC18YG/UC18YK>
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. 4) (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.
