Thread stuck to bobbin when pull out the work

[Orrrmygod]

Hi Guys, I’m very new to sewing machine and now learn how to use it. I came across one problem that I could not figured out why.

When I finished stitching and want to pull out the leathers, the thread at the bottom always stuck. So I need to cut the top first then move the wheel to be able to pull the bottom thread out (and it tangles)

Please see attached. It’s it normal that the thread always go over bobbin like that?  And I just realized now that if the pole that pull the thread (at the top) go up (and bottom thread goes pass bobbin) I can pull out the bottom thread from bobbin without any tangled. 

What do you think? Please help.

thanks

Rotate the hand wheel a little more to clear the thread from the shuttle. Also, it looks like the thread is getting caught on the tab on the bobbin case. Adjust your check spring to leave more slack in the top thread. It should go around the bobbin case and shuttle without binding, snapping or getting hung up.

Your last photo doesn't show how you have threaded around your check spring assembly.

Hi Wizcrafts, did you mean this?

Im wonder what is that for too (the middle spring). Should I tight it?

Hi Wizcrafts, Adjust check spring to leave more slack in the top thread - should I make the spring looser or tighter? Thanks

Use the bottom stop bracket to set the throw of the spring. The thread should remain taut until the needle has penetrated the material. The spring tension should be just enough to hold the thread as the take-up lever starts its downward stroke. The spring tension must not override the main tension disks.

Is it mean I should loose the spring tension a bit? And if I loose it too much then what’s gonna happen? Thanks

Btw, I don't think you need to have thread over this pin..

Thanks Katie, if I take the thread out from that pin, the top tension will be less right?
