5. Change rotation speed.
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (see
Figs. 5
and

).
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, con
fi
rm that the switch is o
ff
.
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. Con
fi
rm the clutch dial position (see
Fig. 7
).
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, 3, 5 ... 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

Doing so may cause damage (See Fig. 8).
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. 7
)
The tightening torque di
ff
ers depending on the type of screw and the material being
tightened.
The unit indicates the tightening torque with the numbers “1, 3, 5 ... 21” 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.
