(2) Tightening torque indication
The tightening torque diff ers 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.
4).
(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. 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, confi rm 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.

CAUTION
○ The selection examples shown in Table 4 should be
considered as general standard. As diff erent types
of tightening screws and diff erent 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
loose due to the tightning torque is too strong. Use the
driver drill at LOW (low speed) when using a machine
screw.
6. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill
chuck, fi rmly grasp the ring and tighten the sleeve by
turning it toward the right (in the clockwise direction as
viewed from the front) (See Fig. 8).
○ If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger when
the sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning
it toward the left (in the counter-clockwise direction as
viewed from the front) (See Fig. 8).
