How to use

Select the appropriate drill bit or chisel compatible with the rotary hammer. Secure the workpiece area, set the tool to the required mode (rotation for drilling; hammer or hammer+rotation for impact drilling; chiselling for demolition), and position the bit on the marked point. Apply steady pressure without forcing the tool, allow the impact mechanism to work, and withdraw periodically to clear debris and prevent overheating. Use correct feed rate and consistent motion when chiselling to control removal depth and avoid damage to surrounding surfaces.

Usage recommendations

Use appropriate personal protective equipment such as eye and ear protection, dust mask and gloves. Choose bits and chisels rated for concrete and masonry. For prolonged tasks, allow intermittent cooldown periods and verify power connections meet local safety standards. Follow tool maintenance guidelines: keep ventilation openings clear and inspect the accessory mounting system before each use.
