Regular Maintenance Routines

To ensure your machine operates smoothly, follow these regular maintenance routines:

Adjusting Thread Tension

Ensuring proper thread tension is critical for achieving high-quality stitching. Follow these steps to adjust the thread tension on your ZHONGLIAN border stitching machine:

Step-by-Step Instructions

1. Access the Tension Dial

3. Adjust the Tension

4. Rotate the tension dial clockwise to increase the tension or counterclockwise to decrease it.

5. Test the Adjustment

6. Run a small sample to check the tension. If the stitches are too tight, increase the tension. If they are too loose, decrease the tension.

7. Fine-Tuning

   
   
8. Gradually adjust the tension dial until the stitches appear even and consistent.

Common Mistakes and How to Avoid Them

• Over-Tightening: This can cause thread breakage and poor stitch formation. Ensure the tension is not set too high.
• Under-Tightening: Loose stitches will not hold the mattress border well and may cause unraveling. Ensure the tension is set appropriately.

Bobbin issues can lead to poor stitching and machine jams. Here are some steps to troubleshoot bobbin problems:

Troubleshooting Steps

1. Check Bobbin Spool
2. Ensure the bobbin is the correct size and type for your machine.
