How to adjust incorrect thread tightness on Brother KE-430C Sewing Machine?
Incorrect thread tightness can be due to: * Upper thread tension being too weak; adjust the upper thread tension. * Lower thread tension being too weak; adjust the lower thread tension. * Thread take-up spring tension and height being incorrect; adjust the tension and height of the thread take-up spring.
What to do if Brother Sewing Machine thread is jamming?
Thread jamming can occur if: * The thread take-up spring tension and height are incorrect; adjust them. * The needle and rotary hook timing are incorrect; adjust the needle bar lift amount. * The shuttle race thread guide is not separating the threads; adjust its position.
Why is my Brother KE-430C Sewing Machine lower thread breaking?
The lower thread may break because: * The lower thread tension is too strong, so adjust the lower thread tension. * The corners of the needle hole plate or bobbin case are damaged; file smooth or replace the affected part.
Why is the thread coming unthreaded on my Brother Sewing Machine?
The thread may come unthreaded due to: * Stitches being skipped at the sewing start; refer to “Skipped stitches occur”. * Uneven needle thread; adjust the sub-tension. * The needle thread being too short; adjust the thread take-up lever stroke.
How to fix Brother KE-430C when needle breaks?
A needle can break for the following reasons: * The needle is touching the rotary hook; adjust the needle clearance. * The needle is bent; replace the needle. * The needle is too thin; use the correct needle for the material. * The needle is striking the button; refer to “6. CHECKING THE SEWING PATTERN” in the Instruction Manual.
What to do if my Brother KE-430C skips stitches?
Skipped stitches can occur for several reasons: 1. The clearance between the needle and rotary hook tip might be too great; adjust the needle clearance. 2. The needle and rotary hook timing could be incorrect; adjust the needle bar lift amount. 3. The driver might be contacting the needle too much (except KE-484C); adjust the driver needle guard. 4. The needle could be bent; replace it. 5. The needle might be installed incorrectly; install it correctly. 6. The needle thread might be too short; adjust the thread take-up lever stroke.
