How to use

Fit an appropriate 115 mm disc for the intended task and ensure the disc is compatible with the grinder and rated for the material. Secure the side handle in the preferred position and adjust the protective guard to shield the user from sparks and debris. Hold the tool with both hands, switch on the motor and allow the disc to reach full speed before engaging the workpiece. Apply steady, controlled pressure and avoid forcing the grinder; let the disc perform the cutting or grinding. After use, switch off the tool, wait until the disc stops completely and disconnect from the power supply before changing accessories or making adjustments.

Usage recommendations

Use appropriate personal protective equipment such as safety goggles, hearing protection and gloves. Choose discs certified for the material and follow disc manufacturer safety limits. Maintain the tool by keeping vents clear of dust and checking the condition of the guard, handle and power cord regularly. For tasks requiring long continuous operation, allow the motor to cool periodically to preserve performance and prolong service life.
