Brother LX3125 Sewing Machine Questions & Answers
How do i fix the top thread just tangling, looping on the shutter race?
1. Make sure that you are using the right bobbin case. (LX3125) 2. Adjust the tension of the bobbin case.
(I've sent a guide for this) Your's is considered the older style.
3. Make sure the bobbin that is used is the right one. If it is too long or too wide it will cause problems.
4. When you insert the bobbin case make sure the lock handle goes down flat with the bobbin case. Also, feel the bobbin case for rough snags.
5. Replace the needle. Insert it the new one in the right direction.
6. Thread the machine (while pressure foot up) according to the directions. While threading give small tugs to check for snags.
7. Place the tension on four. It is ok to feel by hand if this is excess tension.
8. While turning the hand wheel towards you the bobbin thread should rise above the throat plate.
9. This should be ok now. Try it on some old rags. Don't forget to set that bobbin case.
How to fix the tangling of top thread on bobbin race.?
1. There are many bobbin cases. Make sure the
right one is installed. Also, once you have it installed
check the handle of the bobbin case to make sure it is going flat with the bobbin case.
2. Check the bobbin you are using. If it is too long it will protrude the
length of the bobbin case. It must be able to spin freely.
3. Check the bobbin case on the outside for any
rough edges that could hang up on thread.
4. The bobbin tension should be checked. I've attached a guide for this. Your's is the older style.
5. Make sure the top is threaded properly. Especially make sure the thread is going through the thread in the right direction.

Why is the thread a line on bottom of fabric?
Clean the bobbin case and all the parts under the plate. You may have a bent needle, so replace the needle. The bobbin case has a tiny point on it that catches the thread, that may be broken and missing the thread as it spins.
Complete bobbin case apart...how to fix it ?
Hai, First you should learn and try to your old machine how to operate the machine? After you started to operate a new machine. Then first you check the timing and change the bobbin case and needle.
