Saveiro box

I have a problem with a saveiro box that brought me unarmed, I don't know and I can't find a manual that tells me what kind of synchronized it carries for the first and second speed. If the simple ring or triple or, failing that of first triple and the second simple. The fact is that the box walks a time well and then the first one is lock and I cannot take it out.

Thank you I hope to get help or a manual that allows me to solve

I guess the 5 speed box. I add the drawing. If it doesn't come out, send me a PM with your email and send it to you. Greetings
