Singer 4411 Heavy Duty Sewing Machine Questions & Answers
How do i adjust the needle bar on a singer 4411
Hi,
I have repaired a few of these machines, and if yours is not stitching the problem is usually that the timing is off. Adjusting the needle bar is one way to get the needle eye and the hook timed but in this case it is not the answer. There is a timing belt that runs from the top to the bottom of the machine.and it has a tendency to jump a tooth putting the timing out. It takes quite a bit of work to get the machine apart, and some patience to get the timing back,
Sorry to say it's no easy fix.

Having trouble picking up the thread from the bobbin
Try a brand new needle. Verify that the machine is threaded properly--both upper and bobbin threads.
If it is still not picking up the bobbin thread, it is likely there is a needle/hook timing issue requiring service.

Why is thread getting caught and unable to pick up the bobbin thread?
try tightening the needle thread tension as it appears to be too lose
try loosing of the bobbin thread tension a fraction as it may be to hard to pull out of the bobbin case under the spring
changing thread sizes and material thickness generally requires a tension adjustment of the threads
