How to use

Select the appropriate operating mode for the required task: rotation-only for wood or metal, hammer drilling for concrete and masonry, or chiseling for removal tasks. Fit a compatible SDS drill bit or chisel, secure the tool with both hands, and position the bit perpendicular to the work surface. Start at low speed to center the hole, then increase speed and apply steady, moderate pressure while allowing the tool's hammer action to perform the cutting. For chiseling, use controlled short strokes and adjust the angle as needed.

Recommendations

Use appropriate personal protective equipment, including eye protection, hearing protection and dust mask. Choose the correct bit type and size for the material and task. Allow the motor to cool during prolonged continuous operation and inspect bits regularly for wear. When changing accessories or performing maintenance, disconnect the tool from the power source.
