Hi Max, I'm afraid the original author of osgManipulator has moved company, where he developed it, over a decade ago so to know exactly how to use it we all just have to look at the code an figure it out. I haven't personally use osgManipulator in the way you are wanting to use it so can't provide any guidance myself.
The only public example I'm familiar with is OpenSceneGraph/examples/osgmaipulator/osgmanipulator.cpp. Cheers, Robert.
