If I am going to reassemble in a short period of time or if it is a place I can leave it undisturbed, I like to set up a table right next to the machine and lay out all of the pieces I remove in the location that they are removed working outward with the parts as they get lower in the stack. Upper most ramps closest to the middle, etc. I also try to put screws and nuts back on to the post they came from if possible.
