Nolan(Flip Up) N102 Visor Removal

[Shoe]

I have a Nolan N102 Flip Up helmet with the exterior dark visor. I have tried searching the internet and can't find
any instructions on how to remove the thing. I need to replace the clear portion of the visor.

Does anybody know how to properly remove and replace the visor?

I found this http://www.stromtrooper.com/general-v-strom-discussion/26317-how-replace-facesheild-nolan-n102.html

And then I found what you want http://www.nolangroup.de/media/pdf/bedienungsanleitung/N102.pdf , page 12?

Thanks. That's what I was looking for.
