Using the DeWalt DWA5960 chisel is easy. First, make sure you've got a 1 - 1/8' hex demolition hammer. Insert the chisel into the hammer properly. When you start working on concrete, the self - sharpening blade will do its job, cutting through quickly and efficiently. Just hold the hammer steadily and let the chisel do the work. As for maintenance, after each use, clean the chisel to remove any concrete debris. You can use a brush or a cloth. Store it in a dry place to prevent rust. Also, always wear safety goggles and gloves when using this chisel to protect yourself from any flying debris.
