How do i attach the preacher curl attachment to my bowflex xtreme 2 se?

i dont have any of the documents for the bowflex because it was given to me from my grandpa 2 years ago when he passed away and i just got room to set it up, and if possible, can someone get me a list of exercises and how to do them on the bowflex? i could only figure out about 15 on my own
