HOW TO USE
1. Confi rm the cap position (See Fig. 4)
The tighthening 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 black dots
with the triangle mark on the outer body.
(2) When using this unit as a drill, align the cap drill mark
“
” with the triangle mark on the outer body.

CAUTION
○ The cap cannot be set between the numbers “1, 3, 5 …
22” or the black dots.
○ Do not use with the cap set at the black line between
numbers “22” and the drill mark “
”. Doing so may
cause damage. (See Fig. 5)

2. Tlightening 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 damaged. Be sure to
adjust the cap position according to the screw diameter.
(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 cap, and the black dots.
The tightening torque 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 cap and align the numbers “1, 3, 5 … 22”
on the cap, or the black dots 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.
CAUTION
○ The motor rotation may be locked to cease while the
unit is used as a 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 force.
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. Whe set to “HIGH”, the drill rotates at a
high
speed.

CAUTION
○ When changing the rotation 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 cap is
“17” to “22”, it may happen that
the clutch does not engage and that the motor is locked.
In suh 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 out.
