    Re: Hard to adjust mazzer

    and now for the best news.

    I pulled it apart completely, to remove all traces of built up muck.
    Cleaned up the adjustment collar and every other part with a range of things from toothpics, hard bristle brushes and toothbrushes. Blew everything out with an air blower and vacuumed everything else.

    Decided i was not going to apply any grease at all to the threads. I figure this way less chance of stray ground coffee getting stuck on them again.
    I thought, if its not smooth enough, i will take the collar off again and lightly grease the first 1/4 of it only which makes contact.

    After re-assembling, it is just like new. Very easy to adjust grind indeed.

    Now i just need to order the little adjustment pin which i snapped off whilst trying to remove the collar yesterday.

    A happy chap once again i am.

    A big thanks yet again to KK for all his help in this matter and to the boys at work

    Well took it to work with me today and had the fitters take a look.
    We used a leather oil filter remover to get it off. Took a fair bit of effort though. Once we got it moving, then the rest by hand was easy enough.
    My gut feeling as I hinted above re cross-threading was gunk & solidified coffee as you described

    Brush & Vacuum all the threads on both top and bottom burr sections for best results

    Only add graphite on the brass touch rings or the contact points of the top burr carrier and the grinder body

    Good to hear it was stubborn but easy once it got going

    I am very relieved that no damage was apparent on the threads ;D

    Looking inside, no wonder it was stuck. The build up of old coffee was very thick.

    Does not look like it has been cross threaded and everything has now been thoroughly cleaned.

    Once everything dries, will put it back together again and see how it all goes.

    Have read posts of people rubbing a little bit of olive oil on the threads, not sure how much of a good idea that is though

    In the US, adusting the grind when the grinder is stopped can void the warranty with some resellers at least.
    Fortunately in Australia retailers dont make their own rules

I tried food safe silicone (Dow 111) and it did not work well AT ALL!. Went with a small schmear of Campy grease worked well into the threads so that it would not enter the grinding area and it works great.

    thanks again guys

    will now give the lubricant a go and see how i go

    Sort of agree with KK, if it was threaded, it should have been very hard if not impossible to wind it all the way back down again.

    fingers corssed

    have sprayed it and will now let it soak in for a while

    2 possibilities on this

    1] If you have cross threaded the collar it will be rare that it would be possible to wind the collar all the way down

    2] If it is wound down all the way its possible that its locked the top & bottom blades together

    i had a funny feeling i may have cross threaded it last time, and i dare say this confirms it.

    I was looking at a new grinder as you know but did hope to sell this one. Not looking good now.

    Can i spray anything onto the threads to get it off, then have it inspected.
    Also any way i can tell if its been cross threaded
    Possibly a lubricant/dispersant and then it will need a real good clean...

    My advice though, take it to Anthony at Genovese. They are an importer and will have the right gear to do the job properly....

    I think i let this one go too long now.
    Today i finally decided to pull it all apart and give it a good clean. Apply some graphite to the threads to make it easier to adjust.

    WELL WELL WELL

    i can not turn it at all now It is stuck so badly that i broke the little lever that screw into the side to help adjust.

    Thats not an issue ans can easily replace it, but there is no hope of getting the adjustment coller off now

    any tips?
    Sorry to hear it John....Sounds like you have cross threaded it to me It should move even without a lubricant.

    I am thinking some protective rubber and a very big vice? Hope there is not too much damage.... :-/

    I hope you did not cross thread the collar when re assembling

    If not & In any case you dont need the adjuster rod to unscrew it

    thanks for the tips, will look in the hardware store for some powdered graphite.
    Just to clarify, i only have it working when adjusting grind, not after a clean and re-assemble

    If you are reassembling after a dismantle there would be no need to have the unit running because there should be no beans in it to cause a jam.

    amen to that Mal Also... be careful while adjusting the collar while grinder is running (especially if youre winding it in after a dismantle). Much damage to be done if it reaches Zero by accident!
