How to troubleshoot a Brother Sewing Machine that does not operate at high speed?
If the machine does not operate at high speed, check if the sewing speed setting or backtack speed setting is incorrect. If so, set the speed to a higher speed using the operating panel. Also, ensure the FVR inside the control box is at the maximum setting by turning it clockwise.
Why is the lower thread not tight on my Brother S-710A?
If the lower thread is not tight, it might be because the lower thread tension is too weak, or the upper thread tension is too strong. Adjust the lower or upper thread tension accordingly.
How to fix a Brother Sewing Machine when the upper thread is not tight?
If the upper thread is not tight, it could be because the upper thread tension is too weak, or the lower thread tension is too strong; adjust the upper or lower thread tension accordingly. Also, the needle and feed mechanism timing might be incorrect; advance the needle timing.
How to fix a Brother Sewing Machine when the needle breaks?
If the needle breaks, it might be due to pushing or pulling the material too hard during sewing. Make sure the needle is correctly installed. Replace the needle if it's bent, broken, or the needle hole is blocked. Adjust the height of the needle bar if the needle and rotary hook timing is incorrect. Retard the needle timing if it's advanced too far with respect to the feed dog.
What to do if skipped stitches occur while sewing with my Brother Sewing Machine?
If skipped stitches occur, check the following: * Replace the needle if it's bent or broken. * Ensure the needle is correctly installed and the machine is properly threaded. * Adjust the presser foot pressure if it's too weak. * Use a thicker needle if the current one is too thin. * Adjust the height of the presser foot if it's too high. * Adjust the height of the needle bar if the needle and rotary hook timing is incorrect. * Adjust the tension of the thread tension spring if it's too weak. * Replace the rotary hook if the tip is broken.
