To All, thank you so much for your help. I asked a manual from Hightex EU and they sent me the attached leaflet (CB7243 is the other name of CB243)...
Also, I took pictures and made videos of my machine, I hope it will cover all the pics you asked for, but in case not, I will take some more !
In order to ease overview of the machine, I did an album :
