How to use

Select an appropriate drill bit or chisel for the intended material and mount it according to the tool's system. Adjust the speed control to a low setting for starting holes and increase as needed for larger diameters. When drilling into masonry, apply steady axial pressure without forcing the tool; let the hammer action do the cutting. For chiselling, select the chisel mode and use controlled, guided strokes while maintaining stable body position and hand support.

Recommendations

Use appropriate personal protective equipment including safety goggles, hearing protection and dust mask when working with masonry. Secure workpieces where possible and clear the work area of loose debris. For prolonged operations, allow intermittent breaks to avoid overheating and inspect consumables such as drill bits regularly to maintain efficiency.
