How to use

Before operation, fit a suitable 125 mm disc compatible with the SDS union nut and check that the disc is intact and correctly installed. Secure the workpiece and wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Start the grinder and allow it to reach full speed before applying it to the work surface. Use steady, controlled movements and avoid excessive lateral pressure on the disc. After finishing the task, switch off the tool and wait for the disc to come to a complete stop before setting the tool down or changing accessories.

Recommendations

Use discs rated for the intended material and an appropriate speed rating for 125 mm accessories. Regularly inspect the SDS union nut and mounting surfaces for wear or damage, and replace worn accessories to maintain safe operation. For prolonged tasks, allow periodic cooling breaks to prevent motor overheating and extend tool life.
