How to use

Install a compatible SDS‑Max chisel according to the tool manufacturer's instructions and ensure the battery is fully charged before operation. Hold the tool with both hands, position the chisel tip on the target surface, and apply steady pressure while allowing the hammer action to do the work. Use controlled, incremental passes when removing large areas of material to maintain control and prevent excessive fatigue. Follow safety practices: wear eye, ear and respiratory protection, and secure the work area from bystanders.

Usage recommendations

For optimal performance, use with the supplied high‑capacity batteries and monitor battery charge to plan battery changes during long jobs. Select chisels appropriate for the material and task — flat chisels for stripping surfaces, pointed chisels for initial breaking — and allow the tool to cool periodically during extended continuous use. Regularly inspect and clean the SDS‑Max shank and bit holder to ensure reliable engagement.
