2. My mechanical sewing machine won't thread with the top thread but the bottom thread is fine: /First/ Check if the needle is bent. It's usually because the spinners point and the needle are not aligned correctly. The gap between the spinner point and the needle should be 0.5mm. The timing of the spinner point and the needle should be 1.5mm (1.5mm above the needle hole).

Jumpers:

1. Incorrect threading method. Please re-thread according to the "threading diagram".

2. Incorrect installation of the straight needle - Check the needle height and orientation, ensuring that when the needle moves downward, it is slightly in front of the needle plate hole.

3. The needle tip of the straight machine needle breaks or bends. Replace the new machine needle.

4. If the tip of the curved needle becomes dull, use an oil stone or fine sandpaper to sharpen it, or replace the new curved needle.

5. The tension of the suture is too large or too small. Adjust the tension of the suture appropriately.

6. The curved needle cannot capture the loop of the straight needle on the right side, and the right side of the lower decoration line jumps the needle. The loop of the straight needle is too small, and the jump line quantity should be appropriately increased.

7. The curved needle cannot capture the loop of the straight needle on the left, and the left stitch of the lower decoration thread jumps. The loop of the straight needle is too large, and the amount of jumping should be appropriately reduced.

8. The curved needle cannot simultaneously hold the middle and left straight needle loop, and the middle and left thread traces of the lower decoration line jump needles. Reduce the amount of jumping threads appropriately.

9. The middle of the back of the curved needle, the left needle thread cannot be threaded into the triangular shape formed by the knitting needle thread and the curved needle thread. The middle of the back of the left thread trace jumps through the needle. Check if the seam thread has passed through the bobbins, and check the synchronous operation of the bottom thread cam. If there are any problems, adjust according to the standards.

10. Incorrect combination of the straight needle and the curved needle - Check the height of the needle bar, the synchronization between the straight needle and the curved needle, and adjust as needed according to the standards if there are any issues.

11. Misalignment of the needle with the needle guard check the position of the needle and the needle guard

2. Incorrect installation of the needle. Reinstall the needle, ensuring that the needle groove is directly facing the operator.

3. The needle eye and needle groove of the sewing machine are not smooth. Replace the new needle.

4. Tension of the suture is too high. Adjust the tension of the suture appropriately.

5. The quality of the suture is too poor. Replace with better suture.

6. The thread is thicker than the needle hole, use a suitable thread or sewing machine needle.

7. The threading holes of the machine needle, bend needle, needle plate, presser foot tongue, and threading holes may have burrs or scratches. Use a oil stone or fine sandpaper to re-polish, or replace the damaged machine parts.

8. Incorrect coordination between the needle and the bent needle, the tension needle. Adjust the coordination according to the standard for the needle and the bent needle, the tension needle.

5、断针

1. The pressure of the presser foot is too low, causing the fabric to be delivered poorly and leading to broken needles. Increase the pressure of the presser foot appropriately to ensure normal fabric delivery.

2. If the curved needle collides with the straight machine needle, adjust the position of the curved needle and straight machine needle according to the standard.

3. If the binder needle collides with the straight machine needle, adjust the position of the binder needle and the straight machine needle according to the standard.

4. Misalignment of the straight needle with the needle guard bar Adjust the alignment of the straight needle and the needle guard bar according to the standard.

1. The straight needle is too low, causing the straight needle coil to form too large, leading to interweaving between the coils. Re-position according to the straight needle height positioning standards.

2. The needle plate tongue is too narrow, which can easily cause the straight needle coil to pile up. Replace the new needle plate.

3. The bottom of the curved needle is too narrow and round, which also makes it difficult for the straight needle loops to separate on the curved needle, leading to the loops intertwining with each other and producing a flower needle. Replace the new curved needle.

4. Adjust the straight needle and the bent needle to the standard position of coordination.

7、Stitch Creasing

5. Small pressure foot loses the flexibility of up and down movement, and there is a seam or rust embedded between the large and small pressure feet. Clear the foreign matter between the large and small pressure feet, and remove rust or replace the rusty pressure foot if necessary.

8、Bad threading

1. The thickness of the thread is inconsistent. Replace with better sewing thread.

2. The wire clipper is not working normally. Clear the dust in the wire clipper to ensure smooth wire passing.

3. The positioning of the over-threading device is incorrect. Adjust the tension of the needle thread, the bent needle thread, and the tension of the needle thread.
