Fig. 8
The Adjustment (Fig. 7) consists of a stepped macro adjust and a stepless micro adjust.
NOTE: At standstill, it is not possible to adjust more than 1 step on the macro or 5
steps on the micro ring (when going finer).
NOTE: Not following our recommendations (cleaning, use of oily roasts, ..) and/or not
adhering to the recommended settings (too fine, too coarse –beyond 16) may result
in clogging and/or defects to the Adjustment.
To move from coarse to fine turn the macro-
(top) ring to the right (Direction FINE),
with the grinder running.
To move from fine to coarse, turn the macro ring to the left (Direction COARSE). The
pointer (Fig. 7) indicates your macro-setting. The micro adjust (bottom ring) ranges
from coarse (11) to fine (1) steplessly and allows for even more precise grind settings
(Click 1 on macro ring serves as reference point for the micro ring).

Default Setting
Espressomühlen: 1 = 14g 2 = 18g 3 = 22g
Filtermühlen:1 = 20g 2 = 30g 3 = 40g
PROGRAMMING of time-based versions (T)
The etzMAX User Interface is equipped with three programmable buttons labeled 1, 2
and 3. These buttons adjust the grind time in seconds but not the grind setting
(Coarse/Fine).
Default Setting
Espresso Grinders: 1 = 4.3 sec 2 = 5.6 sec 3 = 7.0 sec
Filter Grinders: 1 = 4.5 sec 2 = 6.7 sec 3 = 8.9 sec
Fig. 9
NOTE: Install Grinder on an even, stable and vibration-free surface. Be aware, that
the weight-based etzMAX is optimized to be used with Portafilters (max. 2kg).
Other receptacles (lighter / heavier) may have an impact on accuracy and cause
malfunctions and/or error codes.
The weighing system is self-regulating. Accuracy improves with the number of
grinding operations within the same parameters (same roast, same setting). After
change of roast or setting, it takes a couple of grinding operations for the system to
adjust accordingly.
To change the setting, proceed as follows:
1. Select a Preset button (1, 2, 3)
2. Press + or –to program the time (in seconds)
3. Once the desired time setting in seconds is reached, press and hold the selected
button for 3 seconds. The display will flash to confirm the setting.
Repeat steps 1-3 to program the other buttons.
TIME-BASED-GRINDING (T-versions)
Press the desired Preset-button (1, 2, 3). Display will show the programmed grind time in
seconds. Press START. While grinding, the display is counting the seconds and comes to a
halt when the custom time is reached. The motor will stop, and display will reset to the
programmed time.
The etzMAX will go into SLEEP MODE after 4 hours of non-use.
To reactivate grinder, press any button on the User Interface.
For grinding in manual mode, press and hold START button until you reach the desired
quantity of ground coffee. Release START button, and the grinder will stop with the display
showing the total number of seconds run. To return to automatic mode, press STOP.
To change the setting, proceed as follows:
1. Select a Preset button (1, 2, 3)
2. Press + or –to program the weight (in grams)
3. Once the desired weight setting in grams is reached, press and hold the selected
button for 3 seconds. The display will flash to confirm the setting and you will hear a
confirmation sound. Repeat steps 1-3 to program the other buttons.
PROGRAMMING of weight-based versions (W)
The etzMAX User Interface is equipped with three programmable buttons labeled 1, 2
and 3 (Fig. 9). These buttons adjust the grind weight in grams but not the grind setting
(Coarse/Fine).
NOTE: Should the etzMAX be in time-based mode (Fig. 12) when being operated for
the very first time, switch to weight-based mode by pressing STOP and 1 for at least
5 seconds.

programmed weight in grams. Press START.
While grinding, the display is showing the
corresponding grams and comes to a halt
when the custom weight is reached. The
motor will stop, and the display will reset to
the programmed weight.
The etzMAX will go into SLEEP MODE after 4 hours of non-use. To reactivate the
grinder, press any button on the User Interface.
SCALE ONLY
For using the scale independently from grinding, press STOP for at least 5
seconds. While in SCALE-mode, all LEDs stay illuminated and the Display
shows 0.0 (Fig. 11). To return to weight-based-grinding, press STOP for 5
seconds.
Time-based GRINDING (W-version)
To switch to time-based mode, simultaneously press STOP and 1 for 5
seconds. The display will now show the time in seconds, while a vertical
line on its left side indicates that you are in time-mode (Fig. 12). To return
to WEIGHT-based grinding, press STOP and 1 for 5 seconds.
To pause the grinding during operation, press START-button. By repeatedly
pushing START-button, the target weight may be reached in small steps of 0.1-
0.2g. For grinding in manual mode (or Purging), press and hold START until you
reach the desired weight. Release the START button. To return to automatic
mode, press STOP.

CLEANING the etzMAX
Cleaning Schedule: For commercial use, we recommend cleaning on a daily basis
or after grinding 1000-1500g of coffee.

NOTE: To remove remaining coffee powder (stuck in between the sealings),
occasionally (after cleaning) turn macro ring to finest setting (Click 1) with the
empty grinder running and back to your settings.
Rotate bean-blocker handle from OPEN to the front. Insert portafilter / place cup and
clear grinding chamber by grinding until empty (8.5g). Remove portafilter.
Disconnect from power supply.
Push both locking levers backwards as far as they will go. Lift off hopper (ensure lid is
closed) and place aside (Fig. 1). Close both locking levers. To remove portafilter
holder, pull it off the hook. Mark down settings!
Remove adjustment by turning the macro-ring counterclockwise (Fig. 14) until you
feel no more resistance. Slowly pull it downwards and out (Fig. 15).
Open locking levers (Fig. 1), place back hopper and close locking levers (Fig. 2).
Carefully rotate bean-blocker handle all the way to the back to OPEN position
(Fig. 2). Connect to power supply.
To clean grinding chamber, insert bottlebrush from above through the hopper
opening. Use small brush to clean the coneholder. If removing coneholder for
cleaning, ensure it`s perfectly snapped in when reassembling.
Reassemble adjustment in reverse order
(reposition at 8 o`clock, see marking
before mounting, Fig. 16). Once
snapped in properly, turn and return to
your previous settings. Insert portafilter
holder / platform onto center hook
(Fig. 5).
NOTE: To clean the grinder or in case of clogging, IT IS NOT NECESSARY to open
the top cover lid. The lid only needs to be opened to replace etzJET (grinding
mechanism) or User Interface.
