For transporting I leave the backglass in and lie the headboard on top of the machine. The bottom of the headboard rests against the neck that supports the headboard. I use foam, bubble wrap or cardboard between the headboard and the cabinet so that if the backglass falls out during transport it doesn't break. I then lightly strap the headboard to the cabinet with a ratchet strap.

If you are transporting many of these, or need to store it on its end to save space, take the rear legs off first, then tilt the machine onto its back with the coin door at the top and the front legs in the air. Take the front legs off. You can then transport it easily with a sack truck or hand trolley. This is what I did when I moved my collection.
