CLEANING

We recommend to clean your etzMAX on a daily basis, especially before longer periods of non-use to avoid for remaining coffee powder to stiffen. 

When reassembling, ensure for the Adjustment to engage properly without applying force.


For more information, please consult the Manual or contact your Dealer. 


CHANGING between OPERATING MODES

Your weight-based etzMAX may be operated in 3 different modes. 
To switch from weight-based to time-based mode (and vice versa), press STOP and 1 simultaneously (for at least 5 seconds). 

To switch from weight-based or time-based mode to Manual Weighing (Scale) mode (and back), press STOP for at least 5 seconds. 

For more information, please consult the Manual or contact your Dealer. 

REPLACING CONEHOLDER

When reassembling after replacing coneholder (or after cleaning), make sure for the Adjustment to engage properly before returning to your previous settings.  Check again, if after reassembling, grinding requires a (much) coarser setting than before. Do not apply excessive force!

For more information, please consult the Manual or contact your Dealer. 


ADJUST your PORTAFILTER HOLDER

To adjust your Portafilter Holder, just move the upper arm up or down by while simultaneously pressing a finger on the back part.

For more information, please consult the Manual or contact your Dealer. 


ADJUSTING the BEAN-BLOCKER HANDLE

If your Bean-Blocker-Handle seems slack, please check its position as shown in the Video.

Tools required: Allen Key 2

For more information, please consult the Manual or contact your Dealer. 


ADDING SHIMS

Shims are part of every etzMAX-delivery. Shimming depends on use, coffee and preferences.


Tools required: Allen Key 5

For more information, please consult the Manual or contact your Dealer. 


REPLACING the USER INTERFACE

Tools required: Torx 10, Torx 15

For more information, please consult the Manual or contact your Dealer. 


CALIBRATING

We recommend to recalibrate your etzMAX every couple of months and/or after having been moved around a lot.

To calibrate your etzMAX (weight-based), you need a 500g calibration weight (i.g. ACAIA).

For more information consult the Manual or contact your Dealer. 


REPLACING the MICRO-/MACRO ADJUST

Please make sure to replace the complete part. Early parts are black/black while the modified ones (available since March 2019) are black/white. When switching from a black/black to a black/white-one, make sure to also replace coneholder. 

We recommend settings between Click 3 and 12. Grinding on settings beyond 16 may result in damage to the Micro-/Macro as will turning the Adjustment to coarsest setting (29). Do not apply any force when turning the Adjustment!

For more information, contact your Dealer.

REPLACING etzJET

When replacing the grinding mechanism unit (=etzJET), make sure to correctly connect and not to jam any cables. 


For more information, please consult the Manual or contact your Dealer. 


ASSEMBLY of the LOADCELL

Tool required: Torx 6

REPLACING the LOADCELL

When replacing the Loadcell, make sure not to damage the wires. It`s important for the Loadcell not to touch the housing of the grinder.
