Sorry for the confusion.
Yo have to take the fader out and pull gently the connectors on the board.
Next you have to de assemble the protective casing of the fader with a little flat screw on top of it. There are little hinges that attach to the fader housing.
Next, with the fader open, you can start to clean it first for any dust that's in there and then try to lubricate the metal parts and guides with a little of silicon lubricant. Watch for the electronic guides that are in the bottom (the electronic board) because you don't want to lubricate them.
When your done, put the protective case again on the fader body and snap it to close it and insert again in the board.
Hope this helps.
Cheers
