I have a brother fs/40 sewing machine, the stitch is not working, it is loose underneath. How do I fix this?

SOURCE: Brother vx790, my stitches are reversed ( top is on botom & bottom is on top )

It sounds like your tensions are out of adjustment. Your upper tension should be between 3-5 and make sure the tension in your bobbin case is not too tight as well. Pull the thread through the bobbin case and make sure it comes out with a small amount of resistance. If no resistance, tighten the tension just a bit, if too much resistance, loosen it just a small bit at a time.

you want to use a blind stitch. Refer to your manual and it should give you details on how to set the machine for that stitch.

Hi, general rule of thumb:: loops on the top, problem on the bottom.. Loops on the bottom, problem is on the top.. When threading your machine, stop just before you thread your needle, put the presser foot down. Try pulling the thread. If it pulls easily, the thread is not thru the tension wheel right. If it pulls hard, you got it right.

SOURCE: stitching loose. won't thread the fabric

try to rethread the machine all the way back to the spool of thread and check the top and bottom tensions on scrap of same fabric

SOURCE: Brother XL--2600 Sewing Machine not picking up Stitches at all!

Take the thread out, Take the needle plate out Watch as the needle comes comes down, make sure the hook is just above the eye of the the needle as it makes its pass by the scarf of the needle if not refer to my post on timing.
