Hello there, loosen your top thread tension,if it looping on top of the material the tension is way too tight, you will also find changing the thread size to smaller thread, the top tension will also reduce,depending on application a good size thread to use is 25 grade,bobbin tension should have just a slight amount of drag as the top thread and bottom work against each other when sewing.

adjust your tension.You probably did not wind your bobbin properly as well.Make sure you oil your machine every month or so and make sure your bobbin is seated properly before you sew.
Go slower with the pressure foot speed and use the right needle.ALWAYS test on scrap of your sewing material first!!!

I have this machine for like 2 years and can do 2-5oz cowhide and buffalo leather on it (no joke, and it works FLAWLESSLY) inside it has full steel construction,just needs regular oiling compared to pro machines and easily made a few grand $$$ with it while my pro machine is getting repaired (I don't even bother with my pro machine anymore) But you MUST oil it every month and use the RIGHT needle and adjust your tension properly
Also pull out the thread a good 6 inches from the needle and bobbin before dropping the pressure foot and sewing.
Best $70 bucks (WITH TAX) I spent hell,the leather I use costs more than the machine!

There could be several things causing this.
First, be sure the bobbin is in the bobbin case correctly. There is usually a line diagram showing the correct placement or you can check the owner's manual.
Second, make sure your needle is inserted correctly. If it is not completely set in the housing, this can prevent the bobbin thread from being caught by the hook. The groove in the needle should be ffacing toward you to assure that the thread interacts with the hook.
Third, be certain the upper threading is correct...passing through all thread guides and correctly through tension and take up lever.
Finally, make sure the bobbin case is free of lint. The machine brush that came with the machine will clean this area well.
I hope one of these suggestions helps you solve your problem. If so, please come back to Fixya and rate my advice!
