BATTERY REMOVAL/INSTALLATION

1. Battery removal
Hold the handle tightly and push the battery latche
(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 direction. (see
Fig. 2)
CHARGING
Before using the driver drill, charge the battery as
follows.
<UC9SD•UC12SD•UC14SD>
1. Insert the battery into the charger.
Insert the battery firmly while observing its direction,
until it contacts the bottom of the charger. (See
Figs. 1 and 3)
CAUTION:
The UC9SD, UC12SD and UC14SD models are
the exclusively designed chargers. These cannot
charge batteries except the specified batteries.
It is possible to insert the batteries other than
the specified into the chargers and some of
them may light up the pilot lamps. However,
you are requested to exercise utmost caution
not to charge batteries other than specified ones
because these can not only be charged but also
such actions can result in the malfuntion of
chargers.
If the batteries are inserted in the reverse
direction, not only recharging will become
impossible, but it may also cause problems in
the charger such as a deformed recharging
terminal.
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 AC outlet and check the
battery mounting condition.
3. Charging
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 temperatue for batteries (EB914, EB1214L,
EB1414) is 10 – 40°C, and batteries that have become
hot should be cooled for while before being
recharged.
NOTE:
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
first, then start charging.
4. Disconnect the charger's power cord from the
receptacle.
5. 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.
<UC14YFA>
1. Connect the charger's power cord to a receptacle.
When the power cord is connected, the charger's
pilot lamp will blink in red. (At 1-second intervals.)
2. Insert the battery into the charger.
Position the battery so that the nameplate faces
toward the caution plate of the charger and push
in the battery until it contacts the bottom plate. (See
Fig. 1 and 3)
CAUTION:
If the battery is inserted in the reverse direction,
not only recharging will become impossible, but it
may also cause the fuse to blow, or problems in
the charger such as deformed charging terminals.
3. Charging
When inserting a battery in the charger, charging
will commence and the pilot lamp will light
continuously in red.
When the battery is fully charged, the pilot lamp will
blink in red. (At 1-second intervals.) (See Table 1)
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown
in Table 1, according to the condition of the charger
or the rechargeable battery.
Malfunction in the battery or
the charger
The battery temperature is high,
making recharging impossible.
