What is what?

[Krasi]

I'm starting with all the appologies in the world for the lame question I'll ask - which clicker does what?

Here are pictures of my suspension (09 EC300):

Pic 1 - Front Top


Pic 2 - Front Bottom


Pic 1 - Rear Top


Pic 2 - Rear Bottom



The explanations in the User's Manual get me confused, plus the pictures are for Marzochi (I believe) and mine is Sachs. I know all suspensions are similar, but this is the first time I actually fiddle with one. I read a lot but still am quite confused what is what and how it influences the operation of the suspension. I refer to the clickers. Rear spring preload, for example, is pretty straight forward and "common sense".
