There are two black plastic locks on each side (shown with errors). Turn them to release the front ring. Pull the ring and whats behind it out then clear your jam.
If the black plastic knobs are too hard to turn then loosen the philips screw that hold them a little then retighten when done.

What do you mean you are unable to pull the bobbin thread through, elaboration would help solve the problem...
I suspect I'm having the same problem with you if it's anything to do with the top thread looping around in the bobbin holder.
Damn machine!

Make sure the correct needle is installed on the machine. Domestic needles will have one flat and one rounded side on the shaft. Make sure the flat side of the needle is on the back and the groove on the needle also being to the back.
You might also want to make sure the tip of the needle is not broken.
Other than that, your machine could be out of timing.

SOURCE: thread getting stuck
We had he same problem with no solutions posted. Solution: First, make sure the bobbin case is clean. Ours was slightly rusted. The rust acted like a fine sand paper keeping the thread from encircling the bobbin. We used an metal cleaning powder to remove it. we also noticed that the entire bobbin area of the machine was dirty and had oxidation on the metal. We cleaned that as well.
Second, we checked the hook's action. (We took off the ring around the bobbin and removed the bobbin case as well. we left the hook in the machine and then turned the machine. We watched for how well the hook grabbed the thread from the needle.) We noticed that the hook was slightly slow and was not grabbing the thread. The hole in the needle was slightly above the hook as the needle retreated and hook spun around.
To repair this, we took off the front plastic cover (the side facing the operator). There are screws on both sides of the machine for this. After the cover is removed, you will notice a flat bar going from top to bottom about 1/3 from the right of the machine. This bar has four screws. This bar is the timing adjustment for the bobbin hook. Loosen all four screws. If you turn the bobbin by hand, you will see the bar flex back and forth. Turn the bobbin all the way to the right and tighten the screws. The hook should now catch the thread properly.
