Adjusting mazzer super jolly

Recommended Posts

So the postie delivered the super jolly today.... So tonight i've near OD'd on espresso....

 

however.....

 

is it normal for the adjustment ring to be super tight?

 

i know theres a screw to undo - though tbh i didnt notice it initially. But having now undone it, it's actually no different....

 

Super stiff, yet watching videos online they appear to be easy to adjust....

 

any thoughts?


Ghe sboro fioi!

Depends, mine was really stiff at first but i cleaned out and greased the threads and they have eased up a lot since them

Its a pressure/friction fit against the burr carrier and generally meant to be stiff.

 

Although I can adjust mine without the small leverage pin but it takes two hands.

Agree with Jeebsy, if you clean out the threads it does make it easier to adjust.

 

I've got 2 adjuster pins on my SJ and it seems to work well.

Try dismantling the grind chamber - unscrew the adjuster all the way until it seperates from the body of the grinder. Then you can get to the threads to clean them up.

It's a very fine thread (which allows the micro adjustment), and any crud in either set (on the ring that bears down on the top blade carrier or on the grinder body) can cause it to be very tight. So carefully clean up both sets - I use a nice stiff toothbrush for this purpose. There are 3 springs in recesses in the grinder body - be careful not to lose them! They often disappear at that stage when the temptation to empty the grounds out of the chamber is strong, and the grinder is shaken over the bin, upside down.Maybe just take them out and put them somewhere safe!

Once you've brushed the threads clean, try putting the adjuster ring back into the grinder body (but without the top blade carrier or springs). Be VERY careful - you really don't want to mash the threads up by cross threading the two parts. If it feels at all tight at the beginning, STOP. Don't force it!

If it's all nice and clean, you should be able to very easily screw it all the way down to the end of the threads - if it still binds at all, more cleaning is necessary!

When you're happy, you can apply a small smear of lube to the threads, replace the springs and blade carrier, and again very carefully screw down the adjuster ring - it'll need a little downward pressure to overcome the spring resistance this time.

Screw it right down until the blades touch - keep trying to turn the spindle nut in the centre until it won't move any more. When it won't move the blades are in contact. Then coarsen up by about 1/8 of a turn of the adjuster - spin the nut in the centre to verify that the blades are now apart. This should give you a ballpark adjustment to work from.

Unwinding too far at this stage can cause the threads to clog up with ground coffee coffee, replicating the original problem, so don't coarsen up much before you do the first test grind: better to be too fine than too coarse!

Simple, isn't it?! Easy once you've done it once or twice...

 

Good luck! (And don't lose those springs! It won't work with even ONE missing. And don't cross thread it!)

A little pressure downward (on the top burr carrier) with the other hand as you adjust also makes it easier.
