General Polishing Procedure

- Work in Sections: Polish a small area at a time, using overlapping passes. Apply light, even pressure.
- Adjust Speed: Increase speed as needed for cutting, polishing, or finishing, referring to the speed adjustment guidelines.
- Monitor Results: Periodically wipe off residue to check your progress.
- Turn Off: Turn the polisher OFF before lifting it from the surface.
