Why are the upper and lower threads breaking on my Brother Sewing Machine?
If the needle is bent or broken, replace it. Ensure the needle is installed and threaded correctly. Adjust the upper or lower thread tension if it's too weak or strong. Correct the thread release shaft position if it's incorrect. Replace damaged loopers. For needle eyes too small for threads, no direct solution is provided.
What to do if my Brother Sewing Machine is skipping stitches?
Skipped stitches can occur if the needle isn't properly installed, so ensure it's correctly installed. Replace loopers if they are dull. Adjust the needle and looper timing, as well as the clearance between them, if incorrect. Also, adjust the lower thread take-up timing if necessary.
Why does my Brother Sewing Machine not feed work?
The machine might not feed work if the feed dog is too low, so adjust its height. Also, adjust the presser foot pressure if it's too small. If the feed dog is worn out or the presser foot floats, a serviceman should check it. No solution is provided if the feed dog and presser foot work on one side only.
How to fix upper thread that is not tight on my Brother DA-9270 Sewing Machine?
If the upper thread tension is too weak or the lower thread tension is too strong, adjust both accordingly. Also, ensure the upper thread take-up thread guide position is correct and adjust if necessary.
What to do if the seam position is incorrect on my Brother DA-9270 Sewing Machine?
If the seam position is incorrect, adjust the puller timing, puller feed, presser foot pressure, and feed dog height.
