Disasembly of Daewoo DP-51

I am still trying to get some information on the disasembly of my Daewoo DP-51 9MM pistol. I do not have a manuel and the gun does not seem to come apart in the conventional manner by trying to push out the slide stop pin. I have tryed many times in different positions.
If someone out there hase a Daewoo DP-51 and a manuel or at least knows how to get the slide off and disasemble the gun for a good cleaning I would aprechiate your reply!!!!
