There are different versions of the locker assembly, but they are attached to the kiosk in a similar manner.
Older kiosks have a locker assembly that is held in place by nuts in these locations (not all visible in this photo):
Newer kiosks attach the locker assembly with 6 nuts, 3 across the top and 3 across the bottom:
To adjust the locker, loosen the nuts that hold the locker assembly. Do not remove the nuts, just loosen them.
When all nuts have been loosened, push the entire locker assembly to the right, then tighten all of the nuts you loosened.
That is all you need to do. Now you can do tests to ensure the locker opens smoothly.
