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 the black
dots. The tightening torque at position “1” is the
weakest and the torque is strongest at the highest
number. (see Fig. 4).
(3) Adjusting the tightening torque
Rotate the cap and align the numbers “1, 3, 5 …
22” on the cap, or the black 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
⅜ The motor rotation may be locked to cease while
the unit is used as a drill. While operating the driver
drill, take care not to lock the motor.
⅜ Too long hammering may cause the screw broken
due to excessive tightening force.
3. Change rotation speed
Operate the shift knob to change the rotation speed.
Move the shift knob in the direction of the arrow
(see Figs. 6 and 7).
When the shift knob is set to “LOW”, the drill
rotates at a low speed. Whe set to “HIGH”, the drill
rotates at a high speed.
CAUTION
⅜ When changing the rotation speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
⅜ When setting the shift knob to “HIGH” (high speed)
and the position of the cap is “17” or “22”, it may
happen that the clutch does not engage and that
the motor is locked. In suh a case, please set the
shift knob to “LOW” (low speed).
⅜ If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor
or battery may be burnt out.
4. The scope and suggestions for uses
The usable scope for various types of work based
on the mechanical structure of this unit is shown
in Table 1.
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 two hours 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 power cord from the
receptacle.
4. Hold the charger tight and pull out the battery.
PRIOR TO OPERATION
1. Setting up and checking the work environment
Check if the work environment is suitable by follow-
ing the precautions.
HOW TO USE
1. Confirm the cap position (See Fig. 4)
The tighthening 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 black 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.
CAUTIONS
⅜ The cap cannot be set between the numerals “1,
3, 5 … 22” or the black dots.
⅜ Do not use with the cap numeral between “22” and
the black line at the middle of the drill mark. Doing
so may cause damage. (See Fig. 5)
2. Tlightening 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 damaged.
