How to use

Fit the flat chisel securely into the rotary hammer according to the tool manufacturer's instructions and ensure the locking mechanism is engaged. Position the chisel edge on the work surface at the desired angle, then apply steady pressure while operating the rotary hammer in the appropriate mode for chiseling. Move the chisel along intended lines or surfaces in controlled passes, allowing the hammer action to drive the blade through material. Periodically inspect the chisel for wear or damage and replace it if the edge becomes excessively rounded or the shaft is deformed.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Match the chisel shank and tool holder type before use and select a suitable hammer setting to avoid undue stress on the accessory. Store the chisel in a dry place to prevent corrosion and inspect it regularly to maintain safe operation.
