Operate the shift knob to change the rotational speed. Move the shift knob in the direction
of the arrow. (See Fig. 6 and 7)
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 a large force is required for operation, 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. Confirm the clutch dial position (see Fig. 8).
The tightening torque of this unit can be adjusted
according to the clutch dial position, at which the
clutch dial is set.
(1) When using this unit as a screwdriver, line up the
one of the numbers "1, 5, 9 ... 21" on the clutch
dial, or the black dot, with the triangle mark on the
outer body.
(2) When using this unit as a drill, line up the clutch
dial drill mark "
outer body.
CAUTION:
The clutch dial cannot be set between the numbers
"1, 5, 9 ... 21" or the black dot.
Do not use with the clutch dial set at the line
between the number "21" and the drill mark
" ". Doing so may cause damage (See Fig. 9).
7. 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. 8)
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, 5, 9 ... 21" on the clutch
dial, and a black 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. 8)
Rotate the clutch dial and line up the numbers "1, 5, 9, ... 21" on the clutch dial, or the
black 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.
