What to do if my Brother KE-434C 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 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.
