Your FW is beautiful! If you don't have an original manual, I would strongly urge you to download one from the internet (they're free), and print a copy. I have done this for every machine I have that is missing its manual! The first thing you need to do is make certain the machine is clean, well lubricated, properly threaded, the correct needle properly installed and you should be good to go! A FW is very sensitive to thread pieces in, around or under the bobbin case. From there, there are many experts on this board who can and no doubt will help you! I am a rank amateur, but I've learned a lot by listening, reading and maintaining the manuals.
