2. Safety Instructions
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when using power tools.

5. Operating Instructions
5.1 Powering On/Off and Direction Control
The impact wrench is activated by pressing the trigger switch. The speed is variable, controlled by how far the trigger is pressed (0-2200 RPM). To change the direction of rotation (forward/reverse), use the directional switch located near the trigger. Ensure the tool has come to a complete stop before changing direction.
5.2 Using the Impact Wrench
Position the socket squarely over the fastener. Apply firm, steady pressure and press the trigger. The impact mechanism will engage as resistance is met, providing high torque (up to 280 Nm) for tightening or loosening. Avoid over-tightening fasteners, especially on sensitive materials.
