Removing/Replacing Freezer Door Handle

The left side of my freezer door handle came loose after vigorous pulling. I’ve no idea how to go about repairing it, but it seems the first thing I need to understand is how these handles come attached/detached. So, what do I need to unscrew these things and what kind of screw is holding them in?
Any information would be greatly appreciated.

Here is the install sheet.
Take a look at page 19

Just what I needed! Thanks a lot!
