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 continuously 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 fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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,
fi rst let the battery cool, then start charging.
○ When the pilot lamp fl ickers in red (at 0.2-second
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
confi rm that the battery being charged with UC18YML2 /
UC18YRSL / UC18YFSL / UC18YGSL 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 fl ickers 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. Confi rm the clutch dial position (See Fig. 5)
The three modes of screwdriver, drill and impact drill can
be switched by the position of the clutch dial in this unit.
(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.
(3) When using this unit as an impact drill, align the clutch
dial hammer 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 Fig. 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 diff ers depending on the type of
screw and the material being tightened.
The unit indicates the tightening torque with the numbers
"1, 3, 5 ... 22" on the clutch dial, and the dots. The
tightening torque at position "1" is the weakest and the
torque is strongest at the highest number (See Fig. 5).
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers "1, 3, 5 ...
22" on the clutch dial, or the dots, with the triangle mark
on the outer body. Adjust the clutch dial in the weak or the
strong torque direction according to the torque you need.
CAUTION
○ The motor rotation may be locked to cease while the unit
is used as drill. While operating the driver drill, take care
not to lock the motor.
○ Too long hammering may cause the screw broken due to
excessive tightening.
3. Rotation to Impact changeover (See Fig. 5)
The "Rotation (Rotation only)" and "Impact (Impact +
Rotation)" can be switched by aligning the drill mark
"
" or the hammer mark "
the outer body.
○ To make holes in the metal, wood or plastic, switch to
"Rotation (Rotation only)".
○ To make holes in bricks or concrete blocks, switch to
"Impact (Impact + Rotation)".
