2. General Safety Instructions
Always observe the following safety precautions when using power tools to prevent electric shock, fire, and serious injury.

5. Operating Instructions
5.1 Powering On/Off and Speed Control
- To Start: Press the ON/OFF switch (trigger). The integrated LEDs will illuminate the work area.
- Speed Adjustment: The speed of the impact driver is controlled by the pressure applied to the ON/OFF switch. Pressing lightly results in lower speed, while pressing fully increases the speed up to 2300 RPM.
- To Stop: Release the ON/OFF switch.
5.2 Direction of Rotation
The direction of rotation (forward/reverse) is controlled by the selector switch located above the trigger.
- Forward Rotation (Screwing In): Push the selector switch to the left.
- Reverse Rotation (Screwing Out): Push the selector switch to the right.
- Lock Position: When the selector switch is in the middle position, the ON/OFF switch is locked, preventing accidental activation. Always engage the lock when not in use or when changing bits.
5.3 Using the Impact Driver
- Select the appropriate impact-resistant bit for your screw type and material.
- Position the bit firmly on the screw head.
- Start the tool by gently pressing the trigger, increasing pressure as needed. The impact mechanism will engage automatically when resistance is met, providing additional torque.
- Maintain a firm grip on the tool. The low reverse torque design helps reduce strain on the user.
