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.
The unit indicates the tightening torque with the
numbers “1, 3, 5 ... 22” on the clutch dial, and a
dots. The tightening toque 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. Change rotation speed

Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (See 

Figs. 7

  and 

8

).

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.

When setting the shift knob to “HIGH” (high speed)
and the position of the clutch dial is “17” or “22”,
it may happen that the clutch does not engaged
and that the motor is locked. In such a case, please
set the shift knob to “LOW” (low speed).

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.

4. The scope and suggestions for uses
