I would like to change oil seals in my fatty cartridge. To do this i must disassemble the shafts from the piston, how is this done?

You need to remove the air from the fork, remove the cartridge from the fork using a Cannondale "castle tool" then the top and bottom white Delrin caps can be un screwed using a green and a yellow park pin spanner. Change oil, according to the type of cart you have, there are different techniques to bleed the cart, re insta;ll, re air, ride.
