(2) Regarding the temperatures of the rechargeable
battery
The temperatures for rechargeable batteries are as
shown in Table 2, and batteries that have become
hot should be cooled for a while before being
recharged.
Table 2 Recharging ranges of batteries
Rechargeable batteries
BSL1430, BSL1830
(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the recharging time will become as shown
in Table 3.
Table 3 Recharging time (At 20°C)
(AC power supply/DC 12V (in-car) power supply)
Charger
UC18YML2
Battery
BSL1430, BSL1830 Approx. 45/120 min. Approx. 45 min.
NOTE:
The recharging time may vary according to the
ambient temperature and power source voltage.
<UC18YML2>
Especially, using a DC 12V in-car power source may
require longer recharging time at high temperatures.
CAUTION:
When the battery charger has been continuosly 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.
4. Disconnect the charger's power cord from the
receptacle or cigarette lighter socket
5. Hold the charger firmly and pull out the battery
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
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 is charged while it is heated because
it has been left for a long time in a location subject
to direct sunlight or because the battery has just
been used, the pilot lamp of the charger lights up
green. In such a case, first let the battery cool, then
start charging.
When the pilot lamp flickers in red (at 0.2-seconds
intervals), check for and take out any foreign objects
in the charger's battery connector. 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 UC18YML2/UC18YRSL 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.
Check the voltage of the in-car power source when
the pilot lamp flickers in green (every 0.2 seconds)
continuously. (UC18YML2)
If the voltage is 12V or lower, it indicates that the car
battery has weakened and cannot be charged.
If the pilot lamp does not blink in red (every second)
even though the charger cord or cigarette lighter
connecting plug is connected to the power, it indicates
that the protection circuit of the charger may be
activated.
Remove the cord or plug from the power and then
connect it again after 30 seconds or so. If this does
not cause the pilot lamp to blink in red (every second),
please take the charger to the Hitachi Authorized
Service Center.

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 (WH14DBDL / WH18DBDL)
Always follow the following procedure to install driver
bit. (Fig. 5)
(1) Pull the guide sleeve away from front of the tool.
(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.
4. Selecting the socket matched to the bolt
(WR14DBDL / WR18DBDL)
Be sure to use a socket which is matched to the bolt
to be tightened. Using an improper socket will not
only result in insufficient tightening but also in
damage to the socket or nut.
A worn or deformed hex. or square-holed socket will
not give an adequate tightness for fitting to the nut or
anvil, consequently resulting in loss of tightening
torque.
Pay attention to wear of socket hole, and replace
before further wear has developed.
