Troubleshooting

• Skipped Stitches: Check if the needle is bent or dull, replace if necessary. Ensure the needle is inserted correctly. Verify proper threading of the upper thread and bobbin.
• Thread Breakage: Check for correct threading, ensure the thread tension is not too tight, and inspect the needle for burrs or damage.
• Uneven Stitches: Adjust the upper thread tension dial. Ensure the bobbin is wound evenly and inserted correctly.
• Machine Not Starting: Check if the power adapter is securely plugged in. Ensure the power switch is in the "L" or "H" position.
