Refitting hinged shelf covers?

The hinge on one of the shelf covers on my Kyoto freezer has cracked and come out. I have repaired the crack successfully, but in order to refit the shelf cover I need to be able to take out one of the hinges from the freezer. There is no obvious way of taking the hinge out without breaking it. How does on take the hinge out from the freezer?
