3. Operating Instructions
3.1 Powering On and Off
The screwdriver is activated by pressing the main trigger button. There is no separate power on/off switch.
3.2 Using the Direction Dial
The innovative three-shift dial located at the rear of the screwdriver controls the rotation direction and locks the tool.

- 'L' Position (Screw Out): Rotate the dial to 'L' to set the screwdriver to rotate counter-clockwise, used for loosening or unscrewing fasteners.
- Center Position (Locking): Rotate the dial to the center position (indicated by a dot) to lock the screwdriver. In this position, the trigger will not activate the motor, allowing for manual tightening or loosening if needed, or for safe storage.
- 'R' Position (Screw In): Rotate the dial to 'R' to set the screwdriver to rotate clockwise, used for tightening or screwing in fasteners.
3.3 Activating the LED Lights
