I had a similar problem.  I was typically using a setting of 8 or 9 with a few different bags of beans with great results.  Tried a new bag of 4 Barrel's Friend Blendo, and could never get it to pull correctly, always too fast.  As I tigntened the grind, it just caused the grinder to jam.  I gave up and instead ground those beans with my hand grinder which worked well.  Went back to a different bean, and I'm pulling again at 8 or 9.

I'm puzzled by this, and I don't want the Preciso to jam or break.

You may want to do this check list from Baratza's web site. Click Here (www.baratzallc.com) My problem is the part where you put pressure on the adjustment ring, I am loose at the 11 and 3 o'clock positions while 7 o'clock is solid. I have a choice for a new grinder or to fix it myself with new parts. At first I was going to get a replacement but considering almost every package I have received recently looked like gorillas did all the handling I think I will just get the parts to make sure I have a second espresso grinder for the holidays.


Craig, I see above you mention a way to take the grinder apart that has a softer touch but I do not see a description of how to do so, sorry if I missed it. Would you point me in the right direction? When I look at Baratza's directions I can see in the pictures the scares from the screwdriver.

Hi Rob,

There isn't a description on how to do it on the Baratza website. It's the way I do it for my Baratza grinder refurbishing.

Couldn't be simpler.. After taking off the bean hopper, turn the grinder upside down & pry out the clear plastic feet. Then it's a #2 Phillips screwdriver to remove all four (4) base attachment screws. Remove the metal base plate.
Find a suitable (not too skinny but wide enough flat blade screwdriver) & then proceed to gently pry the casing away from the base at all four indented outer grinder casing slot positions. {;-)

When you'e done, don't forget to take a pair of pliers & squish down each clear plastic foot., this plumps up the diameter of each foot slightly so that they'll be a nice snug fit again.
The reason being that during removal, the feet become enlongated & stretched slightly & will be loose if you put them back like that.

Brian, that's the BEST way to do it in my opinion., no offense to Pierce or whomever made the service pdf. Doing it the way listed on the pdf, I've seen more than a couple of damaged, gouged, scratched grinders coming back in for refurb that way.

NO ONE wants to buy a refurb if it's beat up & looking like Hell, & myself & other Baratza service centers are left with grinders that won't or can't sell (I for one will not in the condition I've seen some of the bases!)., then having to wait for a shipment of used bases to replace/swap out the buggered up ones..

Posted November 30, 2011 link

Thanks Craig.

This is the post I was referring to and as I mentioned before I can see the on the pics in the PDF their grinder is all buggered up where the screw driver was used to pry the case open. I will use some wooden or plastic shims for the leverage points to try and avoid the dings and scratches.

Good advice for the feet, mine are stored away since the Preciso is paired with the Esatto but I will give them a crimp so they are good to go if I need to reinstall them.

Yes I know the post you were referring to.
It's probably a reserved test grinder that they use over & over (test unit) to teach the new tech/s on utube vids, etc.. Shims? My way you wouldn't need to do that as the base is OFF, then you're separating the plastic base from the plastic casing., no metal base to accidentally ding, scratch with the screwdriver prying against the sidewall of the metal base..

So looks like I have a problem with my...Preciso...changed settings to do some espresso, gushers and it will not adjust fine enough anymore...

Posted December 9, 2011 link

This happened to me yesterday, but I chalked it up to past-peak beans. Then this morning I was getting gushers using fresh beans 3 macro settings down from my usual sweet spot. I checked the adjustment ring and found it was much looser at the 11:00 position. Colin at Baratza is sending me out a refurbished replacement Preciso featuring two upgrades: a beefed up adjustment ring (reinforced with fiberglass) and a quieter gearbox. While I wait for the UPS guys to saunter across the country with the "new" grinder, I think I'll be able to use the old Preciso (bought 6/7/11, btw) at coarser settings. The press grind still appears good (just checked).

p.s. Rob, thanks for the email earlier.

Do you know if all new preciso machines will be featuring those two upgrades?

^^^ Hi. That was suggested in another thread, but I'm not sure (didn't ask Colin).

I would imagine so. They wouldn't use 'old' parts in new 2012 grinders I'd think.

I've been aware of the new parts for some time now, being a/the Canadian Baratza warranty & repair service technician. The 'quieter' gearbox is nothing more than a new baseplate for the "teething" problem that was mentioned by another CG member a while ago.
Now that it's been know for some time on the CG forums & common knowledge, I can talk or discuss about this.

Anything you'd like to know about, more than likely I have an answer. {;-)

No one has really asked me any direct questions, so I haven't provided the answers..
