How to use

Charge the rotary grinder fully before first use according to the manufacturer’s charging instructions. Select the appropriate accessory from the 70-piece set and secure it in the collet or chuck following the tool’s fastening method. Hold the tool firmly with one or both hands as needed, apply light pressure and move steadily over the work surface to avoid gouging. Use lower speeds and finer accessories for delicate materials and increase aggressiveness only as required. After use, switch the tool off, allow rotating parts to stop, and store the tool and accessories in the protective case.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and a dust mask when grinding, cutting or sanding. Match accessory type and grit to the material and task to achieve consistent results. For prolonged work, allow the tool to cool intermittently and follow battery charging and storage guidelines to preserve battery life.
