New to MPC 2000XL

Hey I just got a MPC 2000XL and I wanted to know about things that I should never ever do while using this machine. For example don't push this while it is doing this etc. I love what I have right now and I don't want to screw it up doing stupid things... And also if anyone know about changing powercord or supply when I move to differnt countries, please let me know. Right now I'm in the US but I'm going to Korea and they have a different powercord and I don't want to burn my thing plugging different things...
Thank you!! I migh be asking some stupid things constantly but if you guys help me out that will be great!
