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.
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 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. Confi rm the clutch dial position (see Fig. 9).
The tightening torque of this unit can be adjusted
according to the clutch dial position, at which the
clutch dial is set.
Clutch dial
Weak
Strong
(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 drill
mark "
" with the triangle mark on the outer body.
CAUTION
● The clutch dial cannot be set between the
numbers "1, 3, 5 ... 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. 10).

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. 9)
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 ... 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.
(3) Adjusting the tightening torque (See Fig. 9)
Rotate the clutch dial and line up the numbers "1, 3,
5, ... 21" 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.
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.
● 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.
● Too long hammering may cause the screw
broken due to excessive tightening.
8. Using the light
Pull the trigger switch to light up the light. The light
keeps on lighting while the trigger switch is being
pulled. The light goes out after releasing the trigger
switch. (Fig. 11)
