| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Thread breaking | Incorrect tension/rough spots | Adjust tension; check for burrs on needle or throat plate |
| Skipped stitches | Bent needle/wrong needle type | Replace needle; ensure correct needle for fabric |
| Uneven feeding | Dull feed dogs/lint buildup | Clean feed dogs; check for wear |
| Treadle stiffness | Needs oiling/belt too tight | Lubricate joints; adjust belt tension |
| Bobbin thread nests | Incorrect bobbin threading | Rethread bobbin; check bobbin case spring |
Regular cleaning prevents lint buildup and ensures smooth operation.
Use soft brush to remove lint from bobbin area and feed dogs. Wipe exterior with dry cloth. For stubborn residue, use mild soap solution on cloth only - never spray directly on machine.
