There is an adjustment on the side of the black bobbin case.

Remove the needle plate, to gain access to the case. Lift it out, noting how it is positioned! On the side of it , there are two screws, one is the adjustment screw - its the one that sits out more. To increase tension, turn it clockwise 1/8th of a turn, reassemble and test sew. (make sure the top thread tension is back to where it should be). Repeat if required. DO NOT adjust too much at a time!

Good luck

My Bernina 1630 A straight pin was struck by the needle and went into the needle hole. I changed the needle, but the bobbin tension is loose. Is there an adjustment for bobbin tension?

There is. It's the little screw on the side of the bobbin case. Be sure to mark its position BEFORE making any changes and turn it only 1/8 to 1/4 of a turn per adjustment.

However, if the pin damaged the bobbin case or anything else, that may need to be repaired or replaced. Sometimes, just biting the bullet and purchasing a brand new bobbin case eliminates a lot of frustration--not that expensive. Besides, I have several bobbin cases on hand because I change thread weights between quilting and regular garment sewing and it is just easier to have a bobbin case set up specifically for one use--eliminates the need to make constant adjustments to the bobbin tension between projects.

Be sure you've changed out the old needle. It could also be an easier fix by just removing all the thread and rethreading the machine again--always raise the presser foot when threading the top thread.

I am not sure about this particular machine but in most machines there will be a nob on the front loose low numbers like 0 1 -2 work well on number 3. If the nob is not on the front check and see if it is on the side.

How do I fix my loose bottom tension?

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread the machine from the beginning. Verify the path is correct. The standard tension setting is the midway point although you will most likely need to tweak this for your particular machine.

If you are still having problems, you may need to readjust the bobbin tension.

I have juki 1541industrial machine . It started sewing upside down . Instead of nice stiching on top show side it on bottom. Any ideas

This is caused by the tension between the bobbin and needle threads being out of balance. If the knots between the stitches are on the bottom side, then you need to tighten your needle thread tension a little at a time until the knot is in middle of fabric. The reverse of this is if the knots are on the top, then either your bobbin tension is too loose or your needle thread tension is too tight. If this occurs, then loosen your needle thread a little at a time to see if knot goes down in middle of fabric. If it does not, then you need to increase the tension on your bobbin thread. This done by taking bobbin case out and tighten the small screw located in the middle of the spring on the side of the case. You only need a slight, steady pull on the bobbin thread - the more you put on the bobbin, the more you are going to have to put on the needle thread.

Top zigzag is fine, bottom is loose

sounds as if it has insufficient top tension, clean between discs then re thread with presser foot down

Mega Quilter tension inconsistent

change the needle--needle must be correct one for fabric sewn
adjust the top tension--make sure there is no lint or loose threads
in the top tension dial
also clean under the needle plate & in the bobbin area for lint or loose threads
make sure the bobbin is inserted correctly--some bobbins only go one way

Thread keeps breaking

Have you got the needle in the correct way around - the thread must lie in the groove in the needle. Is the machine correctly threaded? Try release the tension a bit and check that the bobbin tension is not too loose and bunching up under the needle plate. The instructions for bobbin tension setting are:- Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out. This might not be exactly the same as yours but should give you an idea of the position.

Top thread is way too loose. I've tried adjusting the tension with absolutely no change, as if I hadn't done anything at all.How can I fix this?

A couple of things to try:

1. When you pull on the thread at the needle does it pull through without any tension? If so unthread it completely and rethread it again.

2. If there is resistance but you're thinking it is too loose because of loops in the stitch check your bobbin tension is too loose.

3. If the problem is with the stitch and there seems to be tension at the needle itself, and you've checked the bobbin tension, check the needle. Make sure it is the right size and type and that it is in correctly

My bobbin stitch is loose. I have tried adjusting tension and have changed the needle.

A. To correct loose stitches, try the following: (1) Balance the thread tension. If the stitches are loose on top of the fabric, decrease the tension to the next lower number. If they are loose on the underside set the tension to the next higher number. (2) Make sure the needle/upper thread follows the threading path. (3) Check to see that the bobbin case is threaded properly. (4) Use a different size needle. For fine fabrics, use a smaller needle (size 9, 11); medium-weight fabrics require a size 14 or 16. And use a size 18 or "Denim" needle for heavy corduroy or denim.
