Question and answer
Number of questions: 6The feed teeth that move the fabric forward fell down, how do I lift them up? The lever on the back is not working.
This message has been automatically translatedCan the lower thread be easily removed? It does not sew the same on both sides. The white thread does not look the same as the top one, it is tight. I have already changed the tension and stitch length remains the same.
This message has been automatically translatedTake a full turn of the wheel of my machine and stop completely as if it were hitting something, and then do the same thing when going back.
The bobbin thread gets tangled when I sew while the top stitch remains intact. Additionally, it sounds like the needle is hitting the bottom 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 missing something? Or should I go to a technical service?
How to center the needle? Despite selecting the center position for the needle, the bar where the needle is located is slightly shifted to the left. Greetings
