Pry the dust seal down and then remove the circlip that holds the oil seal in. I used the heat gun to warm up the outer leg to assist with removal, and then in a slide hammer action pull the upper and lower legs apart.
Place all parts in order in a clean work area.
Next, mount the cartridge in the vice and remove the compression assembly using your tool. I took the time to crack them and make sure they'd undo while the fork was still on the bench as a whole.
As the comp assembly unthreads it will pop up a bit. I find stroking the shaft in will push the whole assembly up some more. You can then hold the comp adj and pull the shaft down and you will hear it pull some air into the forks. Each time you cycle it back up it will push the assembly out a bit more until it comes out. Be careful if pulling on it as it will 'pop' out.
