Well I "translated" it with Babelfish, and it does indeed appear they are writing up instructions for getting the cog ON REALLY TIGHT. So you can brake without a lockring and not have it come loose maybe? Hard to tell, the Babelfish "translation" is so awful:
This method of serration of the pinion on the ship-boy - instruction of master GIOVANNI PETTENELLA - allows a perfect assembly without having to resort to the traditional metal ring of closing for the blocking of the pinion on the same ship-boy. The serration is sufficient to resist also al block goddesses pedals, and inverting the spin senses it indicates to you can be removed the pinion without having to rerun on the credit side use of special tools.
Pinion on the ship-boy? Block goddesses pedals? The dice of implantation? WTF?! (pronounced "what the". The F is silent).
I believe the part about "inverting the spin senses it indicates to you can be removed the pinion" means to loosen, just reverse the direction. Word.
