I found this grinder in my city, it is very lightly used. I know is a big machine but the price is very low(about 130$) so i want it to buy. Here is link of the grinder:

This is a grinder built by Rossi, and has the same specs as the RR45, except they advertise as quiet and with micrometric adjustment. 64mm grinder are the mainstay commercial espresso grinder class, and produce very good quality. The RR45 is noisy and rough in adjustment; if this grinder addresses those problem, you have a bargain.

I bought this grinder and started to clean it, but i forgot to take a note where the ring for coarse position was, so now please tell me how to assemble it. What higher number means, is it a coarser grind?

It's the direction that screws the burr out.

You bought a used grinder, with no instruction manual, and you don't know which direction coarsens the grind. You probably won't be able to make this work unless you find someone local who knows espresso gear. There's only so far you can go by getting information on a forum, and learning how to fix and maintain used espresso grinders when knowing nothing about them is a step too far.

I'm not familiar with this grinder, but the collars of most grinders are reverse threaded. Clockwise = coarser, Counter-clockwise = finer. How to find the grinder true zero point explains how to find the espresso zone for a smaller grinder, but the principle is the same for all grinders (e.g., for a Mazzer, the espresso zone is 1/8 to 1/4 turn from where the burrs make contact). Better yet, learn how to dial in any grinder by touch; Fine tuning grinder setting with minimum waste explains how.

Touching...
I didn't know a lick when I started out either. I shadowed this forum for over a year without joining because of the strong potential of that kind of response.
Then I decided I didn't give a **** and that I would post, ask questions and hope someone would be kind enough to want to explain things to me on here. Luckily that happened.

In all fairness the vast majority of Jim's responses are sympathetic and enormously informative, including for newbies. I wouldn't make that much of it.

My mistake, the grinder is Brasilia RR45. I want to ask how can i know that my burrs are for change. I found the zero point on the grinder i backed up 1 point. At this point with this grind and good tamp i only get 15 secounds of extraction. So is the coffee too coarse?
