Why is the thread coming unthreaded on my Brother KE-435C 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 Sewing Machine 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-435C Sewing Machine 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.
Why is my Brother KE-435C Sewing Machine upper thread breaking?
There are several reasons why the upper thread might be breaking: * The upper thread tension may be too strong, so you should adjust it. * The needle might be installed incorrectly; make sure it is installed correctly. * The thread might be too thick for the needle; use the correct thread for the needle. * The thread take-up spring tension and height could be incorrect; adjust them. * The rotary hook, needle hole plate, or needle might be damaged; file smooth or replace the part. * If using synthetic thread, it might be melting; use a thread cooling device.
What to do if my Brother KE-435C is skipping stitches?
If your Brother Sewing Machine is skipping stitches, it could be due to: * Too much clearance between the needle and rotary hook tip - adjust the needle clearance. * Incorrect needle and rotary hook timing - adjust the needle bar lift amount. * The driver contacting the needle too much - adjust the driver needle guard. * A bent needle - replace the needle. * The needle being installed incorrectly - install the needle correctly.
