Why is the lower thread not tight on my Brother Sewing Machine?
The lower thread might not be tight because the lower thread tension is too weak, or the upper thread tension is too strong. Adjust the lower thread tension or upper thread tension.
What to do if Brother Sewing Machine has skipped stitches at sewing start?
To address skipped stitches and thread unravelling at the start when using your Brother Sewing Machine, try the following: reduce the tension of the thread take-up spring and lower its position. Adjust the pretension if the trailing lengths of the upper threads are too short after trimming. Sharpen or replace the knives if threads aren't being trimmed cleanly. Use a thinner needle if the current one is too wide. Replace the anti-spin spring in the bobbin case if the thread length is too short after trimming, or if the bobbin is spinning loosely. Use the slow start feature if sewing speed is too fast, and adjust the needle up stop position if it's too high.
What to do if skipped stitches occur while sewing with my Brother S-7200B?
If you are experiencing skipped stitches while sewing, consider the following: * A bent needle tip can cause this issue, so replace the needle. * Ensure the needle is properly installed. * Make sure the machine is correctly threaded. * The presser foot pressure may be too weak; adjust it accordingly. * A needle that's too thin could be the problem; replace it with a slightly thicker one. * If the presser foot is too high, adjust its height. * The thread take-up spring might be too weak; adjust its tension. * The needle and rotary hook timing must be correct; adjust the needle bar height and the clearance between the needle and the rotary hook tip.
