How to adjust tension in lemeiux 7000 brother sewing machine

SOURCE: Bobbin tension on Viking 350 Sewing Machine

Viking bobbin case tension adjustment:
When the bobbin runs out, sometimes it bends the bobbin case tension spring. Then tension is too light. Take the bobbin case out of the machine. Tie the loose bobbin thread to the Designer 1 needle plate. Insert the bobbin in the bobbin case. Here’s the tricky part set the bobbin case on the table as if it’s in the machine (Bobbin is visible and sitting horizontal to table top) threaded as if sewing and loose end tied to needle plate (that is removed from the machine). Lift the bobbin case off the table rotate it so that the flat side of the bobbin are vertical to the table and no longer horizontal. Have the bobbin case oriented so that the thread coming out of the bobbin case sprint (slot area where it is put for sewing) is at the top. Lift it high enough that the needle plate is lifted from the table. It should not release thread unless you shake it gently and then a very small amount of thread. The needle plate is the exact weight resistance your bobbin case should have on the thread.

Thread the machine with the presser foot up and then adjust the tension to the setting you need - general purpose sewing thread is around 4.

Threading with the foot raised is important as this opens the tension control and allows the thread to properly seat into the mechanism.

When a sewing machine is threaded with the foot down, the tension is closed and the thread cannot enter as intended and the tension control has nothing to control.

If this does not help, the machine may need the the spring in the tension control replaced. You will have to search for parts on the Internet or check with a Brother dealer.

Refer to page 15 of the manual - http://www.singerco.com/accessories/manuals.html

Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.

Try some metal bobbins, #15 or SA 156. that seems to help. If, you don't have a manual go to brother.com and download one for free

Hi. The upper tension is too loose (even tho it looks ok). If the upper thread is too loose, it can't pull the bobbin thread up to properly form the stitch and you get those messy 'birds nest' on the bottom side of the fabric. I posted a Tip on Adjusting Tension--read that and adjust your upper tension.

Thanks!
