I cannot get the right tension. the thread on the bottom is very loose. what is the correct way to thread the bobbin?
The sewing on the bottom is loose because you don't have enough tension on the TOP thread. First, make absolutely sure you are threading the machine correctly. Next, while using 2 different colours of thread, tighten the top tension dial one number at a time and then checking the stitching, continue tightening the top tension until the sewing is even on the top and bottom of your cloth.
I too have the same problem, however I cannot tighten the top tension anymore than it is. I have tried everything and I cannot get the tension right, any suggestions? Thanks, Jody
If your machine is threaded correctly with good quality size 50 thread, and it still gives you poor stitching on the bottom, you need to have it serviced, maybe a new bobbin case.

SOURCE: Top thread stitches correctly but bottom thread loops.
FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.
SOURCE: thread or bobbin tension
Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.
Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.
Good luck,

Welcome to FixYa!
Loose bottom stitches come from the top, not the bottom. Seems weird, but that's the way sewing machines work.
The dial tension should be set at the mid range and make absolutely sure that you have the machine threaded correctly. Both things will cause a sloppy bottom stitch.
Thanks!
If you find my solution helpful, I'd appreciate a FixYa rating....

This is an issue of your upper thread tension, so take a look at this generic tension solution
If you are in a pickle with your bobbin case, check top tension and bobbin case are free of lint, reset the top tension to 4, and adjust the bobbin tension to suit......some more detail on how to do that, is here

Top tension back to 4 and leave the bobbin tension as is.
Make sure you have a new needle for the type of fabric being sewn installed with the flat side to the back of the machine. A bent needle can sometimes go unnoticed.
Always thread the machine with the presser foot up and this will give proper tension to the stitch.
Check the manual to be sure you are threading correctly (always with the presser foot up) and that the bobbin thread is feeding in the correct direction from the bobbin spool and through the guides.
Take hold of the thread at the needle as you lower and raise the needle to pull up the bobbin thread. Take both thread ends under the presser foot and to the back of the machine.
