Subject: Mazzer Super Jolly - grind adjustment with power off - what are the consequences
 

I've just bought a used Super Jolly, but in the process of moving it I've changed the grind setting whilst the power is off (by about half an inch). Is this likely to be an issue, and if so, what do I do?

Don't have any beans at the moment to test it.

Cheers,

JP

If there were no beans in it when you did the adjustment - no problem.

If there were beans in it, but you adjusted it coarser - no problem.

If there were beans in it and you adjusted it finer - extremely unlikely to be a problem.

Less well built domestic grinders might be a different matter, but Mazzers are built like tanks (as you discovered when you lifted it....)

I wouldn't worry, Mate.

No beans in it, so hopefully should be OK. Thanks.

Slightly puzzled by why it needs to be adjusted with the power on. It's a timer model, so the time is always running out while you're adjusting it (I'm guessing, as I've not switched it on yet).

Cheers,

JP

It's good practice I guess.

From a strictly engineering point of view, I suppose it prevents partially ground lumps of bean being jammed between the burrs if you tighten them slightly.  I doubt whether this would do any harm to the grinder. It may mean though that the burrs don't "settle" into the position they would with the grinder running, bearing in mind that a small adjustment on the collar makes only a miniscule change to the distance they are apart.

I admit to occasionally adjusting mine ever so slightly when it isn't running.  You pull a shot that perhaps runs a fraction too fast, and think - hmm, just half a notch perhaps, and then do it ;o((  I doubt I'm alone in that.....

You'll find though that once you have it pretty much where the grind needs to be, that any further day to day changes will be very small, although the initial process may take you a while.  Mazzer put a grinder-specific sticker on each as it comes from the factory, indicating their assessment of a good starting point for espresso, but on a used grinder you can't assume that would still be valid if it's even there still.  

If you use it for different types of brewing (not generally recommended on here) you'll be making much larger adjustments of course.

For daily small adjustments, like just making the smallest movement possible to the adjustment collar (about all I need to do on daily adjustments) it won't be a big deal but is better if running. As  _____   said, Mazzers are built like tanks so it is unlikely to do much damage. On less robust built grinders, it can jamb beans between the teeth in the burrs and if it has a motor on the weaker end of the scale, you can overload the motor, esp if you made a big adjustment and really crunched a bean solidly.

It is best to not use an espresso grinder for other methods. Firstly, most espresso grinders are designed to allow you to make very small adjustments to them so you will be moving the adjustment a LOT if changing from espresso to, say, drip. Secondly, most espresso grinders are not able to just "go back" to the exact same place they were before you moved them so you will be re-fine tuning them for your shots when you go back to espresso.

Thanks for the replies.

I've now removed the upper burr carrier to clean it. When I wind it back on, I wind it as far as it will go, then put the little screw in that stops it being unwound. Is there any way, other than that it won't turn any further, to know that I have it wound on fully?

One other silly question - I assume that the little notch at the front of the machine (at the 6 o' clock position) is where you line up the number to determine the coarseness of the grind?

Cheers,

JP

No
Yes

Be VERY careful when you reassemble, that adjustment ring is a very expensive part and the body of the grinder is much more so.

The best way to assemble is to put it all together springs etc, then turn the ring BACKWARDS while pressing down against the spring tension until you feel the click of the two thread starts dropping past each other then carefully screw the ring on. It isn't hard but the cost of doing it wrong and getting cross threaded is VERY EXPENSIVE.

Have just zeroed the grinder, and the point at which the burrs start to touch is 4 notches coarser than 3 on the dial.

Does this sound right?

Yes it does. But not because "3" is any sort of standard setting point, but because every grinder Mazzer make is slightly different, so there isn't a single number that is right  ;o)  (mine is close to 9).  That's partly why they also put several screwholes around the adjuster ring just so you can screw the adjustment lever into the best spot.

They all adjust to touching at a slightly different point.  I commented in an earlier reply that Mazzer evaluate every one before it leaves the factory, and put a sticker on what they consider a good starting setting for espresso.

Main reason, apart from small engineering tolerances in the grinders themselves, such as perhaps exactly where the threads engage etc.  is that different sets of burrs may also have tiny differences in their thicknesses.

Sounds good to me.  Hope you're happy with your purchase.

It can jam.  If it does, loosen up a bit and start the grinder then adjust finer again with the grinder running.
