>> Any tips on getting the top/front off of this machine?
What you have to do on these is remove the back first, then disconnect the wiring. After that, I believe it was just some screws on the sides at the bottom, and the whole thing (sides, front, and top) lifts off and forward.
I don't think I ever separated the pieces any further than that, as that gave me all of the maintenance access I needed. I do remember using wood shims against the floor to help level/align it when reinstalling though. Having a helper would be beneficial as well. Good luck!
