saperry,
I found a place that you can order a manual for your machine:

It's the second line down.
Since your machine is similar enough to my 117-812 to use the same manual the top threading would be the same. Here is a picture of how to thread it. This is not your machine, but the threading is the same as far as I can tell.

Remember the hand wheel rotates
away from you, or clockwise rather than towards you like a Singer. If you turn it like you'd turn a Singer it won't pick up the bobbin thread properly.
Hope this helps.
Joe
