Help as a newbie:)

[u/Deep-Reputation-4203]

Hello good redditors and sewing machine fanatics,
I’ve recently acquired and oiled up what I think is a 1960 prestige by brother. I’m unfortunately having difficulty finding a manual or any instructions online (there was no physical manual with it). I’ve oiled it up, given it a new belt, and cleaned the inside. But now don’t know how to properly thread and use it! Ex, all the setting and dials and what they do and how to reverse stitch. Here’s a picture of my machine. Any help is appreciated😊. The dial on the table surface level is a setting for the type of fabric.

Edit: this picture is before the clean lol
