(3) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown in
Table 3.

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 UC18YFSL / UC18YML2 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

Setting up and checking the work environment
Check if the work environment is suitable by following
the precautions.

HOW TO USE

1. Confirm the clutch dial position (See Figs. 5)
The tightening torque of this unit can be adjusted
according to the clutch dial position, at which the
clutch dial is set.
(1) When using this unit as a screwdriver, line up the one
of the numbers "1, 3, 5 ... 22" on the clutch dial, or
the dots, with the triangle mark on the outer body.
(2) When using this unit as a drill, align the clutch dial drill
mark " " with the triangle mark on the outer body.
CAUTION
The clutch dial cannot be set between the numerals
"1, 3, 5 ... 22" or the dots.
Do not use with the clutch dial numeral between
"22" and the line at the middle of the drill mark.
Doing so may cause damage. (See Figs. 6)
2. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity
to the screw diameter. When too strong torque is
used, the screw head may be broken or be injured.
Be sure to adjust the clutch dial position according to
the screw diameter.
(2) Tightening torque indication
The tightening torque differs depending on the type
of screw and the material being tightened.
