Planned setup

  • VFD (frequency converter) for variable wheel speed. The allowed speed range will be labelled on the machine once set.

  • Foot pedal for on/off, so both hands can hold the work.

Operating instructions will be added here when the machine is released.

Safety

  • Safety glasses, face shield and hearing protection.

  • No gloves. Tie back hair, remove jewellery, secure loose clothing.

  • Use a wheel and compound suited to the material. Keep wheels and compounds labelled so they don't get mixed.

  • Hold the work below the wheel centre, light pressure. Small or sharp-edged parts can be grabbed and thrown.

  • The wheels keep spinning after stopping — wait for a full stop before touching them.

  • No wood or composites. No grinding wheels or wire brushes on this machine.

Maintenance

  • Power off before wheel changes, cleaning or service.

  • Keep the shaft ends covered with the cap nuts.

  • Wheel changes and VFD settings are maintainer tasks.

  • The manual is contradictory about wheel-nut thread direction (pp. 21 vs 36) — check the actual nuts before loosening.

  • Maintenance and repairs log
