CAUTION
The push button can not be switched while the
power tool is turning. To switch the push button,
stop the power tool, then set the push button.
8. Change rotation speed
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (See Fig. 9).
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.

9. Switch operation
When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool
stops.
The rotational speed 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.
NOTE:
A buzzing noise is produced when the motor is
about to rotate; this is only a noise, not a machine
failure.
10. Using the hook
The hook is used to hang up the power tool to
your waist belt while working.
CAUTION
When using the hook, hang up the power tool
firmly not to drop accidentally.
If the power tool is dropped, it may lead to an
accident.
6. 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 (See Fig. 6)
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.
(3) Adjusting the tightening torque (See Fig. 6)
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.
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.
7. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the push button.
The L-side of the push button is pushed to turn
the bit counterclockwise. (See Fig. 8).
(The
L
and
R
marks are engraved on the body.)
