You start with taking the top cover off that wheel piece. Then, and this is the trick - the rest of that piece separates into two. There are screws on the bottom holding them together. Once the are separated, the rest will be easy - you will now have access to the screws holding the panels on from the inside. I am sending you a link to the exploded parts diagram so you can see it more easily. Let me know if you still have questions, though.
