Jobo CPE2 - How to remove lift?

I just bought a used Jobo CPE2 processor with lift. I would like to detach the lift for cleaning purposes but can't figure out how to do it. Can anyone help? The processor is a CPE2 (non-plus) and the lift is I think the older model (white clips to attach drum).

Ok, I found out myself. There is a white screw on the left which has to be removed.
