How to use

Before use, select the correct 125 mm accessory and secure it with the appropriate flange and lock nut. Attach the side handle in the preferred position and ensure protective guards are correctly mounted. Connect the grinder to a power source and let it reach full speed before engaging the workpiece. Apply steady, controlled pressure and move the tool along the cutting or grinding line without forcing it. Stop the tool and allow the disc to come to a complete stop before setting it down. Regularly inspect the accessory and guards for wear and replace them as needed.

Recommendations

Use appropriate personal protective equipment — safety glasses, gloves, hearing protection and a dust mask — and ensure workpieces are securely clamped. Choose accessories rated for the grinder’s disc diameter and speed. For prolonged professional use, allow intervals for cooling and perform routine maintenance such as checking brushes and cleaning ventilation slots.
