Regularly clean the machine by removing lint and debris using a small brush or vacuum attachment. Oil the machine as per the manual’s instructions, focusing on moving parts. Replace needles regularly and store the machine in a dust-free environment.

Why is my Singer S0235 not cutting fabric properly?

Ensure the blades are sharp and free from lint or thread build-up. Adjust the blade settings if necessary, following the manual instructions. If the problem persists, consider replacing the blades with new ones.

What thread tension should I use for different fabrics on the Singer S14-77?

For lightweight fabrics, set the tension between 2-3. Medium weight fabrics typically require a tension of 3-4, while heavy fabrics may need a tension setting of 4-5. Always test on a scrap piece of fabric first.
