Question about Brother LS-2125 Mechanical Sewing Machine
Have the tension adjusted correctly and the thread and the thread will no longer get tangled. The cause of this problem lies on the type of thread vs the material you are sewing on.
Brother suggests stitching two or three stitches only, then stop and use the reverse feature to make it as strong as possible so that they do not pull out easily while sewing. It's the same concept as using reverse to be your knot. If the stitches are missmatched to the material being used then the first few become too weak to hold and they pull out giving the machine enough thread to tangle. See is using reverse solves or helps your issue.
If it does, then you know we are on the right track and try changing the thread or the material combination.

Clean out the bobbin area if there are any thread tangles there.
If the bobbin does not fit snugly into the bobbin case, then get new bobbins. You need class A or 15 and they do not cost very much. Make sure they are plastic and not metal.
Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.
Now thread the machine with the presser foot up - always - and see if the tangling stops.
There should be a tension setting for your bobbin thread, as well as your top thread. It sounds to me like your bobbin tension setting is not in sync with your top thread.
most common solution to this is to remove the top thread completely from machine and re thread it with the presser foot UP not down. This will allow the top thread to engage properly in the top tension disc
