GX CS4 Owner's Manual?

Thank you for the detailed diagrams. One other question: There's a thin rubber disc the width or slightly larger than the grease pit in the grease pit of the CS4. If it's supposed to be there, how is it positioned? I ask because I don't see it on the diagram and I bought the compressor used.

It goes in the bottom of the grease well that is attached to the compressor. The grease should be added on top of it. Mine was wrapped also, I just cleaned all the grease out and placed it as flat as possible before adding more grease.
Thank you! I thought it might be something they put in there to block any grease from getting into the piston during transportation.
 
I understand we should turn the grease screw 1/4 turns every few hours. I have only turned mine once. What is the recommended procedure. How much of a turn do you recommend? And how do I know when the grease is empty and what do I refill it with?
Actually need to go light on the grease. They don't need much. My owners manual actually say one full when it begins slowing down. That's doing regular deadhead test and if the time begins increasing then grease. Here a link, to thread of me inspecting my cylinder after 100 hrs. Apparently I'd done some over greasing along the way. Pictures tell the tell.
