I suggest you start with https:
//www.quiltingboard.com/vintage-antique-machine-enthusiasts-f22/how-clean-up-use-vintage-sewing-machine-videos-muv-fav-t167789.html
That's your first step with your new machine. If you have problems or questions, ask them. Someone will likely know the answer or where to find it. Once the machine is cleaned and oiled, try it out. By then, you will be familiar with the machine and can ask some questions.
Congrats on the machine.
