How to tune the RTI Mora?

Thank you weevil, I read the entire manual and it is quite thorough. The manual didn't mention this, but I was wondering if one can add a tiny drop of silicone oil periodically to the witness holes to help further the longevity of O rings? I also liked the idea of slowly releasing the air pressure screw when turning the regulator down when tuning it, no need to dry fire it.
