Demag H45G dragline Manual /information data

[DemagH45G 1]

Hello, I have bought a DEMAG H45G dragline with 2 buckets, and I don't have a manual, I don't have any information data about it. Can someone please help me with knowledge about this machine?! Please! 

I am interested in knowing what kind of bucket does it needs, what hidraulic pumps does it has, anything about it and the engine.

 

Danke schon!
