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 the
dots. The tightening toque at position "1" is the
weakest and the torque is strongest at the highest
number. (See Fig. 7)
(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 selection examples shown in Table 6 should be
considered as general standard. As different types of
tightening screws and different materials to be
tightened are used in actual works proper adjustments
are naturally necessary.
When using the driver drill with a machine screw at
HIGH (high speed), a screw may damage or a bit may

Use for drilling purpose.
Use the bit or socket matching the screw diameter.
Use after drilling a pilot hole.
Table 6
Rotating speed selection (Position of the shift knob)
Clutch Position
LOW (Low speed)
For 4 mm or smaller diameter
1 – 22
screws.
For 8 mm or smaller nominal
1 –
diameter screws.
For 45 mm or smaller
diameters. (DS18DSAL)
For 38 mm or smaller
diameters. (DS14DSAL)
For drilling with a metal
working drill bit.
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. 9 and 10).
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.
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.
Be sure to turn the shift knob.
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 5.

Suggestions
loose due to the tightning torque is too strong. Use
the driver drill at LOW (low speed) when using a
machine screw.
NOTE:
The use of the battery in a cold condition (below 0
degree Centigrade) can sometimes result in the
weakened tightening torque and reduced amount of
work. This, however, is a temporary phenomenon,
and returns to normal when the battery warms up.
HIGH (High speed)
For 6 mm or smaller
diameter screws.
For 4.8 mm or smaller
nominal diameter screws.
For 24 mm or smaller
diameters. (DS18DSAL)
For 18 mm or smaller
diameters. (DS14DSAL)
