Which size of needle you can best use depends on the thickness of the fabric you use. With a thick fabric you should use a thick needle. The packaging of your needle states for which substances your needle is suitable.
Generally, a sewing needle lasts about 7 to 9 hours.
There can be several causes for needle breakage: - Not using the right needle for the right fabric - The needle is set too low - The fabric is not properly guided - The bobbin case is not inserted correctly
Please make sure that the needle is inserted correctly, threaded properly, and that the presser foot is down.
Use the tension dial located on the front of the machine to increase or decrease the thread tension according to the fabric you are using.
Unscrew the needle clamp screw, remove the old needle, insert a new needle with the flat side facing the back, and tighten the needle clamp screw securely.
Check to see if the needle is inserted correctly and not bent, ensure that the thread is not tangled or caught in the bobbin area, and make sure all screws and parts are tightly secured.
Regularly clean the lint and dust from the feed dogs, bobbin case, and needle plate with a soft brush. Oil the machine's moving parts as indicated in the manual using a high-quality sewing machine oil to ensure smooth operation.

This message has been automatically translatedCan the lower thread be easily removed? It doesn't stitch the same way on both sides. The white color doesn't match the top, it is tight. I have already changed the tension and stitch length, but it remains the same.
This message has been automatically translatedGive a full turn to the handwheel of my machine and it stops completely as if it crashes into something and back the same way.
The thread gets tangled when I sew while the top seam remains intact. Additionally, it sounds like the needle is hitting against the bottom part of the sewing machine.
My problem is that in straight stitch, the needle stays only in the left position. The Needle Position wheel does not change the needle position. What do you advise me? Am I overlooking something? Or should I go to a technical service?
