Getting the back piece off of FoodSaver FM-2100?

I am trying to clean the suck hose on my FoodSaver vacuum sealer. To do that I need to get in to the bottom of the machine. I can get an edge but back won't pry off. I'm afraid I am going to break the plastic. Any suggestions? Thanks.

Don't you think that, if it was supposed to be user-accessible, the instruction manual would have something to say about it?

Manual here:

You could always contact the maker and ask
