    suggest you try the following -
    - remove the polished bung on adj collar
    - partly unscrew the phillips head screw (stop screw) out of the collar
    * this now allows full rotation in either direction of the collar
    - (with power cord out / unplugged), in counter clockwise direction ( finer grind setting)turn adj collar
    till the top burr seats on the bottom burr (*AT this point do not attempt to operate grinder)
    * with the top burr / collar off it takes at least 14 plus full turns of the collar to seat both burrs (rough guesstimate / from memory)
    - now in clockwise direction (courser grind direction) back off adj collar approx 10mins on the clock face.
    * you should now refit the stop screw and refit polished cap into the adj collar
    - plug grinder into power point,switch on operate grinder (there should be free rotation of the grinder burrs)
    - slowly turn adj collar untll the burrs lightly touch (fine metal rubbing sound), back off marginally till sound ceases
    - at this point I mark both the collar and the grinder outer case with a white marker pen - true zero
    -back off grinder adj collar 10 minutes on the clockface, mark corresponding point on grinder body
    now you should be fine to start trial and error for grind / tamp settings to suit your machine / beans / tastes
    as stated in many posts on here
    best of luck

    Just as a data point - my K3T in the tea room at work is 20 turns I guess there is a range of variability in this.

    @13bob - the way the thing works is pretty robust and simple - the mechanics of it are that the burr carrier is screwed down to the right area for espresso and the "collar" widget has that irritating stop to limit travel so you can't screw the burrs into eachother. When I had to dismember the grinder I "fixed" the issue we had with it being hard up against the stop by simply attaching the collar to alternative holes in the burr carrier. It was an easy fix.

    But yours does indeed look like it is multiple full turns of the carrier out! The pitch of the thread is very fine, so even 2 turns out is possible (although it is hard to make out the grind size accurately from a picture).

    Very nicely made grinders, IMHO. Kind of brick outhouse engineering which I like... particularly when random people use it!

    Thanks barry, I plan on doing just that. Hopefully I can get it sorted.

    I'd give the vendor a ring first thing tomorrow morning, bob.

    Thanks Steve, that's a fair point you make. I really don't know what the problem is.

    I am in south west WA and I bought the coffee machine and grinder from one of the well known sponsors here located in Melbourne. Sending it back is going to be costly.

    I suggest stop stuffing around with it if you don't know what's going on.

    Take it back to where you purchased it if possible and ask to be shown how to operate and clean the grinder.

    If not, put your ; location up and maybe there is someone near by with the experience or knowledge to help you out in person.

    I agree the instructions for the K3 may as well be toilet paper.

    I had this same issue and I needed to remove the stopper screw and wind the adjustment collar down further then reinstall the stopper screw. This allowed me to grind finer.

    It looks like the top assembly is at least one revolution off. Try to take the collar off, turn the metallic part one revolution clockwise and try again.

    The best I can get at the finest setting is really coarse grinds like saw dust.

    i did all this and the grind is still really coarse?

    I'm about to give up and send it back.

    Ok, it looks like I have the same problem I had before. When I rotate the collar to the finest setting and the screw hits the stopper it is still a very very coarse grind.

    Yes, I thought so.... I had a look and there is no other thread for the stopper screw so I can't relocate it.

    I will try your instructions from your last post and see how I go. Thanks again for your help.

    Align the collar so the silver button is ~1/3 to the left of the chute. Tighten up the black screws and see that when you turn the collar anti-clockwise, the button travels all the way to the right and you have a full range of motion.

    Next start from the position where the button is on the right, make sure coffee goes through and then work to adjust the grind to espresso. If the grind at coarsest setting is too fine, turn off the grinder immediately, take off the collar and undo the metal part one rotation counter clockwise.

    If after the adjustment the button is still far from the chute, simply take off the collar and reposition it so the button is closer to the chute without rotating the top metal part.
