Correct tension ensures balanced stitches.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your sewing machine.
1. Cleaning
- Daily: Use a small brush to remove lint and dust from the bobbin area and feed dogs.
- Weekly/After Heavy Use: Remove the needle plate and clean thoroughly around the bobbin case and hook area.
- Do not use compressed air as it can push lint further into the machine.
2. Oiling
- 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
- Needle Replacement: Change needles every 8-10 hours of sewing or when they become dull/bent.
- Professional Servicing: Consider professional servicing every 1-2 years, especially with frequent use.
