How to use

Fit an appropriate drill or chisel bit according to the substrate and the task, ensuring compatibility with the tool's bit-holding system. Secure the workpiece or mark the drilling position, hold the rotary hammer with both hands for stability, and start at low speed to position the bit. Apply steady forward pressure while allowing the tool's hammering mechanism to do the work; increase speed as needed. For chiselling, select the chisel function if available and maintain control with both hands to guide material removal. After use, disconnect power, remove the bit and perform routine cleaning and inspection before storage.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when drilling or chiselling hard materials. Match bit type and size to the intended hole diameter and material, and follow safe handling practices to prevent kickback or loss of control. For prolonged work, allow intermittent breaks to avoid tool overheating and to maintain user control.
