My needle on my brother CS-100 sewing machine keeps getting stuck on the bobbin case. I think it may need to be retimed but do not know how to do this.

The motor locked up because the thread is tangled.
Solution:
Remove the tangled thread before continuing the operation.
Clean the bobbin case to remove the tangled thread.
After cleaning the bobbin case, insert the bobbin case properly.
If the needle is bent or broken, replace the needle.
Then, thread the upper thread properly, and continue the operation.

When you put back in the bobbin case, there is a little "knub" that sticks out with a flat spot on the right (on the top side of it) that you need to ensure it rests gently to the left of the position finger bracket (silver metal piece, in the square of the bobbin case area its on the right closest to you).

When you put in initially, it was probably twisted clockwise and there was a gap between the knub and the position finger bracket and when you put the needle plate on in jams that bobbin case in that position and the needle just takes chunks out of it..

You might need a new bobbin case, try sanding out the needle marks with sandpaper.

Error E-4: The reverse/reinforcement stich button, needle position button or thread cutter button was pressed while the bobbin winder shaft is moved to the right

Try this for me clean out the hook area under the bobbin case some times dust from thread and cloth build up under the bobbin case and it can push up the bobbin case and cause the same thing to happin.

That usually means there is a problem with the threading. If the thread is pulled through the wrong side of the needle, is wrapped around the top wheels wrong, or the bobbin is threaded wrong, this will usually cause it to jam up by the bobbin. i would suggest re-threading your machine, or if that doesn't work, contacting the problem hotline.

try re-threading your machine. usually when the machine is jammed at the bobbin or when the needle gets stuck to the bobbin thread, it means that there is an error with the thread. make sure that the thread isn't pulled through the wrong side of the needle, wrapped the wrong way around the wheels on the top, and that the bobbin is threaded correctly. if this doesn't work, you may want to contact their hotline.

ok Sim this is a bit tricky but not to tricky first turn the handwheel toward you until the hook is at one o clock postion then slide the case without the bobbin in into the hook area you may have to work the handwheel back and forth alittle but it should slide in just remember that the case should ride in the rim. also take the needle out first that way you wont get stuck trust me it happiens.

I don't know if this is any help, but I would suggest taking it in to a repair store. So here is a way to find places that repair brothers machines. The place near me has done a great job both times I've gone in. Also they usually don't charge for labor, just parts. If they charge for labor it probably won't be much.

I have the same problem and found that the bobbin case is scratched. These are quite expensive so I hope yours is something more simple. Keeping the bobbin area clean is also a necessity.

I had the same problem with my brother vx-1120 sewing machine. I set the needle to lowest position by using the hand crank. Then I loosened the knerled set screw that holds needle in place. Then I moved needle shaft till the eye of needle is just lower than the hook on the shuttle loop maker. It made my mechine work. There are instuctions for ajusting timing on machine but I think these mechines are built to not fix and throw out. Just because there where no ajustment marks at all on machine, any machanical machine will needed to be ajusted sometime.
