Ryobi 2800 CD Gripper help!

I think I may have posted this in the wrong area...so I will try it here!

I've never had to adjust the grippers on my ryobi 2800 CD....I'm in the process of getting a whole new set, however, I'm having a difficult time understanding how to adjust them up and down to the cylinder's edge properly. The service manual diagram doesn't look quite the same as my grippers and the one measurement they give can't be done! That is unless you want the gripper stoppers to hit the inside of the impression cylinder when they go fully open!...is there a proper way to set both the gripper and stopper? An actual picture of the perfect settings would help if it's too hard to explain.

 

Are you referring to the impression cylinder grippers?

 

Yes!...I'm not looking for the pressure adjustment....I want to know how to set them to the correct heighth to the cylinder.
