4. Operating Instructions
4.1 Powering On/Off and Direction Control
- The tool is powered on by pressing the trigger. Releasing the trigger turns it off.
- Use the forward/reverse selector switch (located above the trigger) to choose the rotation direction.
- Push the switch to the left for forward rotation (tightening).
- Push the switch to the right for reverse rotation (loosening).
- For safety, set the switch to the middle position to lock the trigger and prevent accidental starting.

4.2 Speed and Torque Control
- Variable Speed: The tool features variable speed control. The further the trigger is pressed, the higher the speed achieved, up to 1700 RPM.
- 3-Speed Modes: Use the speed selection button (usually near the battery indicator) to cycle through the available torque settings:
- Low Speed Forward: 400 Nm
- High Speed Forward: 600 Nm
- Reverse (with auto-stop): 700 Nm

4.3 Automatic Stop System (Reverse Mode)
When operating in reverse mode, the intelligent automatic stop system is activated. Once the nut or bolt is loosened, the tool will automatically reduce its speed and torque, preventing the fastener from being ejected or falling off completely. This feature enhances safety and efficiency, especially when working in confined spaces or overhead.
4.4 Built-in LED Light
The impact wrench is equipped with a built-in LED light located at the base of the tool. This light automatically illuminates when the trigger is pressed, providing diffused lighting to the work area and improving visibility in dark or poorly lit conditions.
