Hi all,
I'm stumped. I bought a Fiorenzato Pietro T-80 grinder on e-bay and it won't adjust to anything but a very coarse grind. In fact, the burrs seem to be very far apart so it's not surprising that it's a coarse grind. And I can't see any way to remove the burrs. There are three threaded posts coming through the top burr holder. These posts come up into the chamber where the beans drop from the bean hopper. My intuition tells me that those should be screws that I unscrew to remove the top burr. But they appear to be screwed in from the other side. Can anyone give me a hint as to what I might be missing? Is it possible I have to pry this off?
Thanks

One of the best way to remove stock collars is to get a oil filter strap and a piece of 2x2 wood and use it as handle to unscrew them
or a tight strap racket
anything soft that will not mess up the collar
then make sure you clean all thread male and female before re-assemble
spotless clean no coffee residues inside
be very careful not to cross thread since the lower is aluminum

Are you telling me I have to unscrew that notched ring that is used to adjust the grind size? That makes some sense to me but I've been afraid to even try as I'm always warned not to adjust that unless the machine is running. So it is okay? Another issue though - what about the lever I have to depress to turn that ring? It will be in the way of the oil filter wrench won't it? Is it removable?
Thanks for the help.

I don't understand what "left hand thread" means. I guess typically if I were tightening something I would turn it clockwise - so a "left hand thread" would be the opposite and therefore I turn it clockwise to loosen eh?
But what about the fact that you aren't supposed to adjust unless the machine is on? I'm guessing since there's no beans in it it's okay?

What would I do without this forum. I followed your instructions and turned it loose. I'd still be interested to know why it doesn't foul things up to do this when the machine's not running. Now I guess my question is do I assume the burrs should be changed? Is that why it only ground coarse? And, is there anything I can do to circumvent the grounds/doser? Or do I not need to worry about that?
Thanks again for the help.

You can adjust coarser without the motor running, just avoid adjusting finer as beans can become stuck in the burrs.

I was just reviewing this old thread and thought I might post an update. After some good advice that I got here and on CoffeeGeek, I finally learned that my upper burr carrier was just really tight. Some extra effort got it loose, I cleaned everything up really well, put in new 63mm burrs I bought at Espressoparts and this grinder is great. Now I use my Gaggia MDF for the French Press, or travel with my Baby Twin. I cut down the hopper to a size that holds 2 or 3 double shots worth of beans and it now fits under my kitchen cabinets. This grinder turned out to be a pretty good deal.
