I was finally able to buy a Juki DU 1181N and I like it and can see me using a lot, but it didn't come with a manual and was told there wasn't one because it is an industrial machine. I did see that there are several Youtube videos but can anyone please let me know which one would show the correct way to thread the machine. Goldstar Tool (Youtube) and Rogue Stitches (Youtube) show threading the machine differently from Fierce Kittenz (Youtube). It shows one minor difference but it might be important. I am attaching two pictures and would very much appreciate knowing which one is correct. Does the guide above the lower tension discs in the picture have to be threaded once or twice? I hope I am making sense.

Also, I would be happy if anyone can recommend videos that helped them with the Juki DU 1181 machine. Many thanks.
Happy New Year!
