6. Operating Instructions
6.1. Powering On/Off and Speed Control
The tool is powered on by pressing the trigger switch. The speed of the impact wrench is controlled by the pressure applied to the trigger. Pressing gently results in lower speed, while pressing harder increases the speed up to the maximum 3200 rpm.
Image 6.1: Illustration of the stepless speed change. Pressing hard rotates fast, pressing gently slows speed, and releasing the trigger stops the tool.
- Press hard: For fast rotation and maximum torque.
- Press gently: For slower speed and controlled operation.
- Let go: The tool will automatically stop.
6.2. Forward and Reverse Switch
The forward/reverse switch controls the direction of rotation, allowing for both tightening and loosening applications.
Image 6.2: The forward button is used for screwing (tightening), and the reverse button is used for removing screws (loosening).
- Forward Button: Push the switch to the left for clockwise rotation (tightening).
- Reverse Button: Push the switch to the right for counter-clockwise rotation (loosening).
- Ensure the switch is in the central (locked) position when not in use to prevent accidental starting.
6.3. Mode Adjustment and Power Display
The tool features a display for real-time power indication and mode adjustment.
Image 6.3: Close-up of the mode adjustment and power quantity display. This allows users to monitor battery life and select appropriate torque settings.
- The display shows the remaining battery charge, allowing you to plan your work effectively.
- Use the mode adjustment button (if present, typically integrated with the display) to select between different torque settings or operating modes for various tasks.
6.4. Integrated Work Light
The impact wrench is equipped with a scattering light feature to illuminate the work area, especially useful in low-light conditions.
Image 6.4: The integrated work light provides illumination for dark corners, enabling one-hand operation without an additional flashlight.
- The light typically activates when the trigger is pressed and remains on for a short period after release.
- This feature enhances visibility and safety during operation in dimly lit environments.
