Can’t figure out how to thread my industrial sewing machine. I have tried a few things and the thread snapped, have a few more to try.

I wrote to the fashion department at two schools and sent a request to the company, in hopes of finding a user guide. I’m itching to use the machine, and to make something. I got bored with the dress I was making so I quit working on it despite almost being done. I need to go back to the fabric store to buy awesome plaid fabric I saw a few months back. I decided to make a jacket with it, and if I can find it I am hoping for a hot pink lining.
