A pinball machine has a folding backbox head, a delicate playfield under glass, and removable legs. Done right the move is straightforward, but the electronics, glass, and playfield are all vulnerable if you rush.
Pro tip: Photograph the backbox wiring before folding the head so you can confirm nothing pinched during setup.
Watch out: Remove the pinballs before moving, since loose balls roll across and dent the playfield and switches.
