Boobin tension is to loose

You're saying the thread on the bobbin is loose/sloppy? That would be a result of the tension placed on the bobbin during winding. Make sure you are using the correct threadpath to wind the bobbin, or the winding tension needs to be adjusted.

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.

1. Make sure the pressure foot isn't pushing on the material too hard. Loosen it in other words.
2. Make sure the length of stitch is above zero.
3. Check the tension of the threads (above and below). A good starting tension is four. I've sent a guide on how to adjust the bobbin thread. This is one of the usual problems that sewing machine operators have.
4. Check the size of the needle. Also, make sure you have good thread.

First thing I would try is to try to shift the handwheel on the right carefully to see if it would loosen up a little. Next thing would be to get to the screws holding down the needle plate and remove them. Remove the presser foot and the needle from it's clamp. Then slowly try to work the whole thing loose. If you can expose thread underneath the needle plate cut all that you see and try not to cut into the garment. With a little care you should be able to work it loose and out. Don't force anything if you can help it. Particularly the hook surrounding the bobbin case. Too much force and it might be shifted out of time and won't sew right once you get it all clear. good luck.

The whole problem may have started from improper threading or upper tension not operational or too loose. Make sure when you rethread that the upper tension is engaged when the presser foot is lowered and loose when the presser foot is raised. Also when you have the needle plate off that the bobbin case is in the proper position so that it can't turn too much only a very little. Just Enough so that the thread can make its way around without catching.

Needs to be in the tensioner as it winds on or will be loose

have you tried changing the needle?
clean under the needle plate & in the bobbin area for lint or loose threads
also check the top tension

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.

Either your bobbin tension is wrong or, your needle isn't the right length for your machine. The bobbin tension is adjusted by the little screw on the side of the bobbin holder.
