3. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise. (See Fig. 6). (The
R
marks are provided on the body.)
When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool stops.
The rotational speed of the drill can be controlled
by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch
is pulled more.
When releasing the trigger of the switch, the brake
will be applied for immediate stopping.
4. Change rotation speed
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, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
5. Confirm the cap position (see Fig. 9)
The tightening torque of this unit can be adjusted
according to the cap position, at which the cap is
set.
(1) When using this unit as a screwdriver, line up the
one of the numbers "1, 3, 5 ... 22" on the cap, or
the white dot, with the triangle mark on the outer
body.
(2) When using this unit as a drill, line up the cap drill
mark " " with the triangle mark on the outer body.
CAUTIONS
The cap cannot be set between the numerals "1,
3, 5 ... 22" or the white dot.
Do not use with the cap numeral at "22" and the
white line at the middle of the drill mark. Doing
so may cause damage. (See Fig. 10)
6. 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 cap position according to the
screw diameter.

(2) Tightening torque indication (See Fig. 9)
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 cap, and a white
dot. The tightening toque 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 cap and line up the numbers "1, 3, 5,
... 22" on the cap, or the white dot, with the triangle
mark on the outer body. Adjust the cap in the weak
or the strong torque direction according to the
torque you need.
CAUTIONS
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.
When setting the shift knob to "HIGH" (high speed)
and the position of the cap 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.
Too long hammering may cause the screw broken
due to excessive tightening.
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
7. Hand tightening mechanism
This unit has a hand tightening mechanism to allow
use as for instance as a hand screwdriver.
To use, turn the switch off and rotate the body. (See
Fig. 11)
CAUTION
Do not use the hand tightening mechanism for
items such as hexagon sockets that require excessive
tightening. Do not use for loosening screws or bolts
that have been overtightened.
The maximum usable torque this can provide is
230kg-cm.
8. The scope and suggestions for uses
The usable scope for various types of work based
on the mechanical structure of this unit is shown
below.
Use for drilling purposes.
Use the bit and socket matching the
screw diameter.
Use after drilling a preparatory hole.
