(2) Regarding recharging time
Depending on the combination of the charger and
batteries, the charging time will become as shown
in Table 5.

The pilot lamp goes off to indicate that the battery
is fully charged.
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.
3. Disconnect the charger's power cord from the
receptacle
4. 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.

PRIOR TO OPERATION

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

HOW TO USE

1. Confirm the cap position (see Fig. 6)
The tightening torque of this unit can be adjusted
according to the cap position, at which the cap is
set.
(1) When using this unit as a screwdriver, line up the
one of the numbers "1, 3, 5 ... 22" on the cap, or
the white dots, with the triangle mark on the outer
body.
(2) When using this unit as a drill, align the cap drill
mark " " with the triangle mark on the outer
body.
CAUTION:
The cap cannot be set between the numerals "1,
3, 5 ... 22" or the white dots.
Do not use with the cap numeral between "22" and
the white line at the middle of the drill mark. Doing
so may cause damage (See Fig. 7).
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 cap 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.
The unit indicates the tightening torque with the
numbers "1, 3, 5 ... 22" on the cap, and a white
dots. The tightening toque at position "1" is the
weakest and the torque is strongest at the highest
number (See Fig. 6).
(3) Adjusting the tightening torque
Rotate the cap and line up the numbers "1, 3, 5,
... 22" on the cap, or the white dots, with the
triangle mark on the outer body. Adjust the cap 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. Change rotation speed
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (see Figs. 8 and 9).
When the shift knob is set to "LOW", the drill
rotates at a low speed. When set to "HIGH", the
drill rotates at a high speed.
CAUTION:
When changing the rotational speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
