• Grinding: Hold the grinder at an angle of approximately 15-30 degrees to the workpiece. Apply moderate pressure and move the tool smoothly across the surface.
• Cutting: Hold the grinder perpendicular (90 degrees) to the workpiece. Allow the disc to do the work; do not force it. Make shallow passes rather than trying to cut through thick material in one go.
• Ensure the workpiece is securely clamped to prevent movement during operation.
• Avoid applying excessive pressure, as this can damage the disc, motor, or cause kickback.
• Be mindful of the direction of sparks and debris.
