If the machine malfunctions due to the personal sewing of the customer being too thick or too hard, the store will not consider it to be a quality problem of the machine.

Commonly encountered problems and their solutions

Problem one: The needle jumps, and there's nothing on the back, the needle is empty, and on the front it's just a straight line..It just falls off when you pull it!

Solution: The needle jumps, and it's inevitable to fall off when pulling, because the thread on the back is not connected by loops. Normally, it should be connected. The problem causing the needle to jump is that the speed of the fabric entering is too fast, and the machine can't connect the loops on the back in time. Keep your hands holding the machine still, let the machine enter the fabric by itself. If it's still straight, you need to adjust the machine! If you don't know how, please contact customer service, and we will teach you!

Problem 2: There's a bunch of lines on the back, it's stuck!

Solution: The back of the machine always has a bunch of wires, which often causes the machine to stop moving. The reason is that the fabric is being fed too slowly. Keep your hands on the machine still, and pull the fabric to the left side of the machine to speed up the feeding process, and the problem should be solved.

Question 3: I keep losing connection or the stitches are really loose!

Solution: The connection keeps breaking. Make sure the wire only goes through holes 1, 3, and 4. Do not put the wire in hole 2, or it will definitely break.

Commonly Asked Questions:

1. Sewing machine jump thread, how to repair the broken thread
You must have worn thick socks. It's likely that the sewing time was wrong. First, check if the needle is crooked. Crooked needles can also cause this problem.

2. My mechanical sewing machine won't thread with the top thread but it will with the bottom thread. First, check if the needle is bent.
It is usually the wrong placement of the spinning needle tip and the machine needle. The gap between the spinning needle tip and the machine needle is 0.5mm. The time of the spinning needle tip and the machine needle is 1.5mm earlier or later (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

12. Incorrect combination of the machine needle and the basting needle or incorrect position of the basting needle can cause the decoration thread to skip stitches. Check the size of the machine needle and basting needle combination, and check the amount of thread coming out of the basting needle.

Four, Line Break

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

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

7. The needle holes on the needle plate are too small. Update the larger needle hole needle plate or change to a smaller size machine needle.

8. The loose fit of mechanical components is large. Check the fit and wear condition between the hook line mechanism's components, adjust the dimensions according to the standards, and replace the severely worn components.

六、花针

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.

Seventhly, the fabric creases.

1. Incorrect differential feeding ratio Adjust the differential feeding ratio appropriately

2. Adjust the height and position of the feeder teeth to the standard to ensure that the height and position are appropriate.

3. Excessive suture tension - Adjust suture tension appropriately.

4. Adjust the pressure of the press foot to the appropriate level.

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.

Eight, poor thread trace

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.
