2. Clean the Tension Discs:

   • Wipe the tension discs with a lint-free cloth to remove any buildup of dust or thread residue.

Monthly Maintenance

1. Deep Clean:

   • Remove the needle plate and clean the feed dogs, bobbin case, and shuttle area thoroughly.

2. Check Belts and Gears:

   • Inspect belts and gears for wear and replace them if necessary to ensure smooth operation.

3. Test Thread Tension:

   • Sew a few test stitches on scrap fabric to check for balanced thread tension. Adjust if necessary.

Annual Maintenance

1. Professional Servicing:
   • Have the machine serviced by a professional technician once a year to ensure all parts are in good working condition and to address any potential issues.

Common Issues and Troubleshooting

1. Skipped Stitches:

   • Solution: Check the needle for damage or incorrect installation. Ensure the machine is properly threaded and the tension is correctly set.

2. Thread Breakage:

   • Solution: Verify that the machine is threaded correctly. Check for any sharp edges or burrs in the thread path and ensure the tension is not too tight.

3. Fabric Puckering:

   • Solution: Adjust the thread tension and ensure the correct needle and thread combination is being used for the fabric type.

4. Uneven Stitches:

   • Solution: Make sure the machine is threaded correctly, and check the feed dogs for cleanliness and proper operation. Ensure the presser foot pressure is appropriate for the fabric thickness.

Usage Tips

• Test on Scrap Fabric: Before sewing your actual project, test the stitch settings on a piece of scrap fabric to ensure the stitch quality and tension are correct.
• Use Quality Needles and Thread: High-quality needles and thread can significantly improve stitch quality and reduce the likelihood of issues.
• Adjust Presser Foot Pressure: Depending on the fabric type and thickness, adjust the presser foot pressure to ensure even feeding and stitching.
• Keep the Machine Covered: When not in use, cover the machine to protect it from dust and debris.
