Issue with GTS 10 blade lower/rise mechanism

[adrspach]

Looking for some advice. Recently I got myself Bosch GTS 10 table saw. As I strted to set it upo I noticed that to rise it in normal position was very difficult however to lower it was smooth as I would expect but admittedly there was some vibration coming from it. I tried to clean the cogs and the screw and that is when I noticed that when the saw was upside down it raised and lowered smoothly.
Any ideas what it could be or how to adjust it? Thank you.

Is it a Australian model

What I am trying to figure out what bolt (no 23 on the replacement parts scheme) does to the moving mechanism as from the position it should somehow interact with the rise/fall rod. Any sensible ideas?
