How to use

Securely fasten the grinder to a stable workbench before connecting to mains power. Fit appropriate grinding wheels or attachments compatible with the machine’s spindle and ensure wheel guards and eye shields are correctly positioned. Start the motor and allow it to reach operating speed; then present the workpiece to the rotating wheel with controlled, steady pressure, keeping fingers clear of the contact area. Use light passes for sharpening and deburring, and avoid forcing the workpiece into the wheel to prevent overheating and uneven material removal. After use, switch off the machine and wait until the wheels stop completely before performing any adjustments or changing accessories.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and gloves when operating the bench grinder. Select wheel grits and types suitable for the material being worked on, and check wheels for cracks or damage before each use. Maintain a clean workspace, periodically inspect mounting bolts and guards for secure attachment, and allow the motor to cool during extended use to prolong service life.
