(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 3.
Table 3 Charging time (At 20°C)
Charger
Battery
EB9B, EB1220BL
EB930H, EB1230HL
NOTE
The charging time may vary according to
temperature and power source voltage.
4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
After charging, 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
If the battery has been heated right after operation
(or due to sunlight, etc.), the charger's pilot lamp
may not light in red. In such a case, first let the
battery cool, then start charging.
When the pilot lamp flikers in red quickly (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.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC14YF2 is taken out, wait for a minimum of
3 seconds before reinserting it to continue charging.
If the battery is reinserted within 3 seconds, the
battery may not be properly charged.

Approx. 90 min.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions
laid forth in the precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it
is at all loose it could come off and cause an
accident.
3. Installing the bit
Always follow the following procedure to install
driver bit. (Fig. 4)
(1) Pull the guide sleeve back.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original
position.
CAUTION
If the guide sleeve does not return to its original
position, then the bit is not installed properly.

HOW TO USE

1. Using the convenient hook
The convenient hook can be installed on the right
or left side and the angle can be adjusted in 5 steps
between 0° and 80°.
(1) Operating the hook
(a) Pull out the hook toward you in the direction
of arrow (A) and turn in the direction of arrow
(B). (Fig. 5)
(b) The angle can be adjusted in 5 steps (0°, 20°,
40°, 60°, 80°).
Adjust the angle of the hook to the desired
position for use.
(2) Switching the hook position
CAUTION:
Incomplete installation of the hook may result in
bodily injury when used.
(a) Securely hold the main unit and remove the
screw using a slotted head screwdriver or a
coin. (Fig. 6)
(b) Remove the hook and spring. (Fig. 7)
(c) Install the hook and spring on the other side and
securely fasten with screw. (Fig. 8)
NOTE:
Pay attention to the spring orientation. Install the
spring with larger diameter away from you. (Fig.
8)
(3) Using the bit holder
Installing the bit
Slide the bit from the side in the direction of
Fig. 9, and then insert firmly until the groove
on the pit locks in the protruded section of the
hook.
Removing the bit
Securely hold the main unit and pull out the bit
by holding the tip with your thumb. (Fig. 10)
CAUTION:
The bit may come loose from the hook and cause
bodily injury when reversing the direction of the
bit as shown in Fig. 9 or when using the driver with
the bit stored incomplete.
Only Hitachi OPTIONAL ACCESSORIES plus driver
bits (Bit No. 2; Code No. 992671, Bit No. 3; Code
