How to use
Before use, check that the selected disc is rated for the grinder's maximum RPM and that it is suitable for the intended material. Secure the correct disc onto the M14 spindle following the manufacturer's mounting instructions, and tighten with the provided flange and nut. Connect the tool to a suitable AC power outlet. Hold the grinder with both hands where appropriate, keeping a firm grip and maintaining control over the tool while starting it. Apply steady, even pressure during grinding or cutting—avoid forcing the disc into the workpiece. Allow the disc to reach full speed before contacting the surface and move the tool smoothly to prevent gouging or kickback. After finishing, switch off the tool and wait for the disc to stop completely before setting the grinder down.
Usage recommendations
Use appropriate personal protective equipment: safety glasses or a face shield, hearing protection, gloves and respiratory protection when working with dust-producing materials. Select the correct disc type (cutting, grinding, flap, or diamond) for the task and ensure discs are within their service life and undamaged. Maintain clear ventilation for corded operation, and avoid using the tool in wet conditions. Regularly inspect brushes, power cord and guards; replace worn components according to maintenance guidance.
