Mamiya RB67 Pro S manual pg. 15 question.

On page 15 of the Pro S manual it says down to the bottom in the paragraph that starts...Do not turn the revolving adapter... and then it goes on to say, ...and adjustment of the release tip is improper... What do they mean by adjustment of the release tip is improper? How do you adjust the release tip? This is sort of strange wording somewhere or I'm a little dense. (Maybe both.) Can you explain what they are saying here? Thanks. Ric.

I believe the release tip is that we little 2mm wide thin bar right behind where the shutter lug comes back to the film back. If it has not recessed from behind the lug there will be insufficient travel to engage the shutter.
