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

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.
