How to use

Insert the SDS-Plus shank into the rotary hammer’s chuck until it locks according to the tool manufacturer’s instructions. Select appropriate hammer mode and impact energy for the substrate; start with lower settings and increase as needed. Hold the tool firmly with both hands, position the chisel on the target area and apply controlled pressure while allowing the hammer action to perform the work. Periodically inspect the chisel for wear or deformation and replace it if the cutting edge becomes severely blunted or the shank is damaged.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves. Match the chisel width to the task to avoid excessive force on the tool, and avoid side-loading or using the chisel as a pry bar to extend service life.
