Manutenzione
Una manutenzione regolare garantisce la longevità e le prestazioni ottimali della tua macchina da cucire.

- Non utilizzare aria compressa as it can push lint further into the machine.
2. Oliatura
- Refer to your official Singer manual for specific oiling points. Generally, a few drops of sewing machine oil are applied to moving metal parts.
- Oil sparingly; excessive oil can attract lint.
3. General Care Schedule

- Assistenza professionale: Consider professional servicing every 1-2 years, especially with frequent use.
