- Interruttore di sicurezza: The grinder is equipped with a safety switch that cuts off power if excessive pressure is applied to the workpiece. This prevents damage to the tool and potential overheating. Do not attempt to bypass or disable this safety feature.
- Compatibilità del disco: Only use grinding and cutting discs with a diameter of 125 mm or 115 mm that are rated for the grinder's maximum RPM.
