Sliding off the ps3 cover

[JustinCredible2013]

Hello, I need to slide the cover of my ps3 off and can't watch the youtube video because I don't have a VPN(I'm in China). I have undone the bolt at the back under the warranty sticker but I can't seem to slide the cover off. Suggestions?

Have you tried pushing both ways?

I'm pushing on the top ps3 symbolas it says to do and pushing in every direction but its not moving.
