ego question

My question is about breaking down and ego to see the internals. It has two screws on the back, but seems to be possibly glued or secured another way, once those screws have been removed.. My machine runs fine, I'm just wanting to break it down and clean and re-lube it. Any info would be appreciated. Thanks everyone

Pretty sure there is 3rd screw..

Two screws at the back one at the front..

Damn, I must have looked right over the front screw. O will look again tomorrow. Thanks guys. I feel stupid, but at least I'm smarter for it.
