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.

The clutch dial cannot be set between the numbers
"1, 3, 5 ... 22" or the black dot.
●
Do not use with the clutch dial set at the line
between the number "22" and the drill mark

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 a large force is required for operation
(operations indicated in the following chart) set
the shift knob to "LOW". If "HIGH" is set and the
unit is used, it may cause the motor to burn out
or malfunction prematurely.

6. Tightening torque adjustment.
(1) Tightening torque
Tightening torque should correspond in its
intensity to the screw diameter. When too strong
power 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 (See Fig. 9)
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
dot. The tightening torque at position "1" is the
weakest and the torque is strongest at the highest
number.
(3) Adjusting the tightening torque (See Fig. 9)
Rotate the clutch dial and line up the numbers "1,
3, 5, ... 22" on the clutch dial, or the dot, 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.
