How to use

Fit a compatible 125 mm disc with a 22.2 mm bore and ensure the disc type matches the material and task (cutting, grinding or abrasive cleaning). Secure the auxiliary handle for two-handed operation, hold the grinder with a firm grip, and start the tool before contacting the work surface. Apply steady, controlled pressure and move the grinder along the workpiece—avoid forcing the tool. Allow the disc to reach full speed between operations and follow safety procedures such as using protective eyewear, gloves and hearing protection.

Recommendations

Use discs rated for the grinder’s maximum speed and choose appropriate abrasive type for the material. Inspect discs for damage before each use and replace worn or cracked discs. Maintain ventilation when working indoors and follow local safety regulations for sparks and dust control.
