K09650H00 | PROC-CAL/002/03 USER MANUAL | V. 06/04/2022
8. ADJUSTMENT
Remove the hopper lid ( ), fill the hopper
with coee ( ), and replace the lid on the
hopper ( ) (Fig. 3).
Fig. 3
Plug in the grinder, and press the main power
switch (
) to ON position, and open the
bean trap (
) to allow coee to pass into the
grind chamber (Fig. 4).
Fig. 4
8.1. GRINDER SET UP
Place the hopper ( ) on the grind regulator
( ) and make sure the bean trap ( ) is in
the closed position (Fig. 1).
Fig. 1
Lock the hopper ( ) in place using a phillips
head screw driver to gently tighten the
hopper security screw making it match to the
hole at the bean hopper collar (
) (Fig. 2).

K09650H00 | PROC-CAL/002/03 USER MANUAL | V. 06/04/2022
8. ADJUSTMENT
8.3. GRIND ADJUSTMENT SYSTEM
Rotate the grind regulator ( ) until reaching
the grind level desired.
Rotating the grind regulator clockwise will
result in a courser grind; turning the regulator
counterclockwise will result in a finer grinder
(Fig. 7).
Fig. 7
Once you reach the desired grinding point
(
), you can fix the grinding regulation using
the regulation break ( ) (Fig. 8).
Fig. 8
8.2. ADJUSTING THE PORTAFILTER
SUPPORT
In order to ensure the proper distribution of
ground coee in the portafilter, it is possible
to adjust the height of the lower portafilter
support (
) and move the nozzle back and
forth using the wheel to adjust it ( ).
To do this adjustment operation the height:
1. Loosen the screw (
) by using the
Allen Key #4 included with your grinder.
2. Adjust the support (
) to the desired
height using the portafilter as the point of
reference.
3. Tighten the screw (
) with the Allen
Key #4 provided (Fig. 5).
Fig. 5
4.
To move the nozzle forth turn the wheel
(
) clockwise,
and back counterclockwise
(Fig. 6).

Fig. 4
9.2. UTILIZATION
Through the program menu (section 10.4.3),
it is possible to select three distinct functional
modes: PUSH, DETECTION and TOUCH.
9.3. PUSH MODE
In the PUSH mode, a pre-programmed single,
double or triple* dose can be set by simple
pressing the corresponding icon on the TFT
screen ( ).
The preselection of a single, double or triple*
dose will remain active until it is changed by
pressing one of the three numbered icons. This
preselection is refle cted on the TFT screen
( ) with the icon of the active selection in the
secondary color, and the rest of the icons in the
principle color.
Dispensing the preselected dose by pressing
the lower pulse button ( ) one time. When the
grinding cycle begins, a timer countdown will
begin on the TFT screen ( ), which will count
down the timed dose cycle to zero.
9. OPERATION
NOTE: If the coee
throughput is very low, this
is because the coee is
being ground very fine. If
the throughput is very high,
this is because the coee is
being ground very coarse. A
perfect Espresso is produced
when the grinding gives an
infusion of 25 ml of coee in
25 seconds using about 7 g of
ground coee.
NOTE: It is recommended
that this operation be
performed, when changing
to a finer grinding, with the
motor running, to prevent
coee from building up
between the burrs and
blocking the grinder.
8.4. PREPARATION OF THE
PORTAFILTER DETECTOR (OPTIONAL)
1. Place the detector on the double portafilter
(Fig. 1).
2. Check that the detector ring tab is properly
closed (Fig. 2).
3. Make sure that the arrow is in the correct
position on the lower side (Fig. 3).
Fig. 1 Fig. 2 Fig. 3
*Triple dose only can be activated on FRESH MODE
13
K09650H00 | PROC-CAL/002/03 USER MANUAL | V. 06/04/2022
9. OPERATION
On FRESH MODE once the grind cycle is
initiated, it can be paused by pressing the lower
activation button ( ). The cycle will pause, and
will complete the timed grind cycle as long as the
lower activation button is pressed again within 10
seconds. After 10 seconds of inactivity, the grind
cycle will reset to the complete cycle time.
Grind pause can be activated or deactivated
by pressing the lower pulse button ( ). First,
set up by following these steps: MENU /
SETTINGS / GRIND PAUSE.
9.4. TOUCH MODE
In this mode of operation when making the
selection of single, double or triple* doses of
coee by pressing the appropriate numeric
TFT icon screen ( ) starts grinding the
selected dosis without the need to actuate
the lower dose button ( ).
The time set for that dose will decrease to
zero, at which point the dose ends.
On FRESH MODE once the cycle starts
grinding using the lower dose button ( )
and is pressed again, the grinding cycle will
stop. If within 10 seconds it is pressed again,
it will complete the remaining time of the
original dose time setting. After 10 seconds
of inactivity the grinder will return to standby
mode.
To pause by pressing the lower activation
button ( ), you can enable or disable,
accessing MENU / SETTINGS / GRIND
PAUSE .
On FRESH MODE , pause grinding may also
be performed by pressing the active icon on
the TFT display ( ). This pause cannot be
enabled or disabled via the MENU.
9.5. DETECTION MODE
In this operating mode, the grinder detects
the presence of the portafilter through
the movement of a fitted Tag. When the
portafilter with the mounted Tag comes
in range, the system identifies it and
automatically grinds DOSE 2 by pressing
the lower portafilter button ( ) once.
Once Dose 2 is detected, you have 5 seconds
to press the lower button ( ). If you want to
cancel the selection, you can press 1 or 3* (if
the Dose 3* is activated) on the TFT screen
( ). If after 5 seconds, the lower button is
not pressed ( ), the grinder will return to the
standby mode.
9.6. TAMPER
9.6.1. Fixed Tamper (Optional)
Position the portafilter below the tamper and
push up to tamp the ground coee (Fig. 5).

12.2. GENERAL MAINTENANCE OF
THE GRIND CHAMBER
12.2.1. To guarantee the eiciency and correct
operation of the grinder, it is essential to follow
manufacturer instructions and ensure that all
maintenance work is carried out by qualified
sta.
Dull burrs will result in; a lower quality grind,
greater heat generation in the coee and grinder,
increased electrical consumption, and finally it
puts additional stress on the grinder motor.
The steps to follow are:
In order to properly clean the bean hopper ( ),
first empty out all remaining beans and fragments.
• Close the bean trap on the hopper
( )
and
grind out the remaining coffee in the grind
chamber.

grind setting until the recommended amount
is passed through the system and nothing
remains in the grind chamber.
• Clean the hopper ( ) and refill with coffee beans.
• Discard the first 2-3 doses of coffee to assure
that the residual cleaning product is removed
from the grind chamber and set the grind
regulator to the desired setting ( ).
• Following these steps will ensure that the
grinder is clean and ready for use.
• We do not recommend the taking apart of
the grind assembly unless changing burrs, or
removing a blockage/obstruction in the grind
chamber. Removal of the grind assembly
should be performed by a qualified service
technician.
