How to use

Before operation, ensure the correct protective guard and a compatible 230 mm disc are securely fitted. Confirm the mains supply is suitable and that the grinder is switched off before connecting to power. Hold the tool with both hands using the side handle for stable control, and position the workpiece securely. Start the grinder and allow it to reach operating speed before engaging the material. Apply steady, even pressure without forcing the disc. After use, switch off the tool and wait for the disc to stop completely before setting the grinder down. Observe local safety regulations for noise and vibration exposure.

Recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection, work gloves and respiratory protection when necessary. For extended tasks, plan regular breaks to reduce exposure to vibration and noise. Choose discs rated for 230 mm diameter and compatible with the tool's intended cutting or grinding application. Maintain the grinder according to manufacturer guidelines and inspect discs and guards before each use.
