Simply so, how do I adjust the bobbin tension on my brother?
To adjust your bobbin thread to the correct tension, there’s a bit of trial and error to be done. First, thread your machine with a thread of normal thickness. Next, set your upper thread tension to 4 (the normal setting). Then, tighten your bobbin case tension screw.
Furthermore, why is the stitching loose underneath? A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
Also to know, what should the tension be set at on a Brother sewing machine?
Turn the thread tension dial clockwise to tighten the upper thread tension. If the upper thread is not threaded correctly or the bobbin is not installed correctly, it may not be possible to set the correct thread tension.
How tight should bobbin tension?
If the bobbin case doesn’t budge, your bobbin tension is too tight. To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.
