How to use
Before use, fit a disc suitable for the intended task and ensure it is compatible with a 125 mm diameter and M14 thread. Check that the power is disconnected while changing accessories. Hold the grinder with both hands—one on the main body and the other on the auxiliary handle if fitted—to maintain control. Start the tool and allow it to reach full speed before applying it to the workpiece. Use steady, even pressure and avoid forcing the disc into the material. After finishing, switch off the power and wait for the disc to stop completely before setting the tool down or changing accessories.
Usage recommendations
For safe operation, always wear suitable personal protective equipment such as eye protection, hearing protection, gloves and respiratory protection where dust is present. Use discs rated for the grinder’s maximum speed. Allow regular breaks during prolonged work to avoid overheating the motor and reduce user fatigue. Follow local electrical safety rules and the manufacturer’s maintenance guidance for brushes and ventilation openings to maintain reliable performance.
