FAQ

In order to maintain the coffee grinder’s performance quality, we recommend replacing the burrs once the following consumption levels have been reached.rnrnu003cstrongu003eIndicative burr service life per model:rnu003c/strongu003ernMINI El A – El B – Filter | 1~rn189D flat: 400 kgrnrnMINI Aut – Man – Timer | 1~rn182D flat: 300 kgrnrnLUX Aut – Man – Timer | 1~rn195D flat: 400 kgrnrnROYAL Aut – El | 1~rn151B flat: 600 kgrnT151B flat, titanium: 1800 kgrnrnROYAL Aut | 3~rn151C flat: 600 kgrnrnSTARK Aut | 1~rn151B flat: 600 kgrnT151B flat, titanium: 1800 kgrnrnSTARK Aut | 3~rn151C flat: 600 kgrnrnSUPER JOLLY Aut – Man – Dr  | 3~rn33T flat: 400 kgrnT33T flat, titanium: 1200 kgrnrnSUPER JOLLY El – Dr – Aut – Man | 1~rn33M flat: 400 kgrnT33M flat, titanium: 1200 kgrnrnSUPER JOLLY Timer | 1~ – 3~rn33M flat: 400 kgrnT33M titanium: 1200 kgrnrnSUPER JOLLY V PRO El – Aut – Timer | 1~rn233M flat: 400 kgrnT233M flat, titanium: 1200 kgrnrnSUPER JOLLY V Pro Aut – Man  | 3~rn233T flat: 400 kgrnT233T flat, titanium: 1200 kgrnrnMAJOR / V Aut – Man – El | 1~rn151A flat: 600 kgrnT151A flat, titanium: 1800 kgrnrnMAJOR / V Aut – Man | 3~rn151B flat: 600 kgrnT151B flat, titanium: 1800 kgrnrnMAJOR VP Aut – El | 1~rnk151H flat: 1200 kgrnrnMAJOR Dr | 1~rn151B flat: 600 kgrnT151B flat, titanium: 1800 kgrnrnMAJOR Dr | 3~rn151C flat: 600 kgrnrnMAJOR Timer | 1~ – 3~rn151A flat: 600 kgrnT151A flat, titanium: 1800 kgrnrnKONY Aut – El | 1~rn191C conical: 600-800 kgrnrnKONY Aut | 3~rn192C conical: 600-800 kgrnrnROBUR / S Aut – El | 1~rn186C conical: 800-1000 kgrnrnROBUR / S Aut | 3~rn187C conical: 800-1000 kgrnrnKOLD / S Aut – El | 1~rn186C conical: 800-1000 kgrnrnKOLD / S Aut | 3~rn187C conical: 800-1000 kgrnrnZM (filter) | 1~rnk151F flat: 1.200 kgrnk151G flat: 1200 kgrnrnZM (espresso/filter)rnk151I flat: 1.200 kg

Mazzer recommends cleaning the coffee grinder on a frequent basis, even daily or, once a week at the very least. In fact, the ground coffee in the grinding chamber, chutes and doser, oxidises rapidly and the oil that is naturally released can make the beverage taste slightly rancid, if not removed on a regular basis.

You can clean it with just a brush, or preferably even a vacuum cleaner or dry cloth. Never use water or other products such as cleaners or abrasives.

The parallel flush-set burrs are factory-guaranteed, as long as the burrs are replaced with original Mazzer burrs and the burr holders have not been knocked or damaged. For this reason, we recommend that you never overtighten the burr-securing screws, so as to avoid having to use hammers or screwdrivers to remove them at a later date. If these tools are used, they can cause the burr holders to incline, in turn compromising the correct final parallel positions of the burrs. The burrs and grinding chamber must be kept clean and it is necessary to ensure that the burr holder that the burr rests on, is fully cleaned.

Mazzer burrs do not need to be “broken in” as they are ready for use. When they are first installed, grind some coffee doses in order to ensure that they are working correctly. Do not use these first doses to brew coffee.

If the motor rotates but the coffee does not come out or it comes out with difficulty, you may have inadvertently ground the coffee too finely and obstructed the burr’s outlet holes. We recommend turning the ring nut 2 numbers towards the coarser grind setting, until the flow is regularised (for the Kold and Kold S models, we suggest a one and a half-turn towards the coarser grind setting). Then proceed to find the correct grind size. If the problem persists, we recommend cleaning the grinding chamber and its outlet chute.

Mazzer burrs cannot be resharpened. We strongly advise against any tampering (heat treatments, surface treatments and coatings, etc.).

Yes, Mazzer designs and produces both flat and conical burrs in its factory near Venice.

The barista usually chooses whether to use an appliance with flat or conical burrs, based on the premises’ workload, potential peaks, personal preferences and the characteristics of the coffee used (origins and roasting profile). Whilst the conical burrs rotate at a lower speed than the flat burrs, they can achieve higher productivity levels than those of flat burrs with the same diameter. Due to the low grinding speed, the conical appliances ensure greater acoustic comfort. Furthermore, conical burrs wear much more slowly than flat burrs, which in turn, reduces the frequency of maintenance work. Appliances with flat burrs offer greater reactivity to the adjustment change, due to the more compact grinding chamber. The choice between flat and conical is up to you. Mazzer is committed to offering a wide range of choice, so that every barista can find the ideal product for their coffee.

TIPS

Each time that the burrs are replaced, the correct grain size must be set on the appliance. In the table below, we suggest the main adjustments, according to the appliance model. It is an indicative reference that will need to be adapted to your own coffee type (adjustment range calculated based on a standard Italian espresso with an extraction time of 20-30”).rnrnSuggested grain sizernrnKOLDrn9 complete turns of the knob from the point of contact of the burrsrnrnKOLD Srn9 complete turns of the knob from the point of contact of the burrsrnrnKONYrnEspresso at approx. 7 numbers from the point of contact of the burrsrnrnKONY Srn9 complete turns of the knob from the point of contact of the burrsrnrnMINI GRINDER-DOSER | LUX | SUPER JOLLY GRINDER-DOSERrnEspresso at approx. 1 number and 4 notches from the point of contact of the burrsrnrnMINI ELECT | SUPER JOLLY ELECrnEspresso at approx. 2 numbers from the point of contact of the burrsrnrnMAJORrnEspresso at approx. 1 number and 4 notches from the point of contact of the burrsrnrnMINIrnEspresso at approx. 1 number and 4 notches from the point of contact of the burrsrnrnMINI FILTERrnFilter (V60) at approx. 3 numbers from the point of contact of the burrsrnrnROBURrnEspresso at approx. 7 numbers from the point of contact of the burrsrnrnROBUR SrnEspresso at approx. 9 numbers from the point of contact of the burrsrnrnSUPER JOLLYrnEspresso at approx. 1 number and 4 notches from the point of contact of the burrsrnrnSUPER JOLLY V PrornEspresso at approx. 3 and 1/2 number from the point of contact of the burrsrnrnMAJOR VrnEspresso at approx. 4 numbers from the point of contact of the burrs

Once the burrs have been changed, we recommend opening the grinding collar 5 notches away from the point of contact of the burrs (found when the motor is off) and grinding 5/6 g of coffee, in order to check that the operation has been successfully completed and to ensure that the burrs are parallel. The resulting ground coffee should have similar characteristics to talcum powder, i.e. a very fine homogeneous particle (be careful not to grind too much coffee at this adjustment point because you risk clogging up the burrs). After this check has been completed, the appliance can be adjusted to the espresso grain size. Please refer to the adjustment table

Once the new burrs have been installed, we recommend thoroughly cleaning the adjustment ring’s thread and counter-thread. Apply a small amount of oil or vegetable fat to the thread and try to screw the adjustment ring without the upper burr holder until it reaches the end, in order to evenly distribute the lubricant and ensure that the component slides correctly. Once this has been completed, the upper burr holder assembly and adjustment ring can be tested. Make sure that all the springs are in place before closing the appliance back up.

After the appliance has been cleaned, yet before the grain size is adjusted, make sure that the grinding chamber and chute have been completely filled with coffee: the grain size will only correspond to that adjustment point if these are full. The first doses ground into an empty chamber, will have a significantly coarser grain size than the doses obtained when the appliance is fully operational.

Whenever the burrs are changed, ground a few coffee doses. Do not use these initial ground doses to brew coffee.
