7. Mantentzea
7.1 Garbiketa-zapiak
- Clean pads frequently during use with compressed air, a vacuum, or a pad conditioning brush tool to maintain consistent performance.
- After finishing work, clean pads with warm water and a mild soap. Rinse thoroughly to remove all residues.
- Allow pads to air dry completely. This prevents solvent-based compounds and cleaners from remaining and protects the foam's cell structure.
7.2 General Tool Care
- Regularly check air connections for leaks and ensure they are secure.
- Store the tool in a clean, dry environment when not in use.
- Do not over-saturate the pad with compound; too much compound can lead to diminished performance.
