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 place the main power
switch ( ) I - 1 AUTOMATIC / 0 - 0 OFF / II
- 2 MANUAL to position I - 1 AUTOMATIC,
I and open the bean trap ( ) to allow coee
to pass into the grind chamber.
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 ( ) (Fig. 2).
Fig. 2
8.2. ADJUSTING THE TOP
PORTAFILTER SUPPORT
In order to ensure the proper distribution
of ground coee in the portafilter, while
supporting the portafilter in a hands-free
position during dosing, it is possible to adjust
the height of the upper portafilter support (
).
To do this adjustment operation:
1. Loosen the screw on the upper support
( ) by using a #2 Philips screw driver.
2. Adjust the support to the desired
height using the portafilter as the point of
reference.
3. Tighten the screw with the #2 Philips
screw driver (Fig. 4).

8. ADJUSTMENT
8.3. ADJUSTMENT OF THE
ALUMINUM PORTAFILTER HOLDER
(OPTIONAL)
In some grinders, it is possible that the portafilter
holder is made of aluminum. If this is the case,
it is possible to adjust the height of the lower
portafilter holder and also adjust the position of
the portafilter forward and backward in relation to
the coffee outlet.
To perform this adjustment:
1. Loosen the screw on the lower holder using
the hexagonal Allen wrench No. 3 included
with your grinder.
2. Adjust the holder to the desired height,
using the portafilter as a reference point.
3. Tighten the screw using the provided
hexagonal Allen wrench No. 3 (Fig. 6).
Fig. 6
4. With the provided hexagonal Allen key
number 3, tighten or loosen the screw located
on the front of the portafilter to find the correct
position as seen in (Fig. 7 y Fig. 8).
Fig. 7 Fig. 8
8.4. 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
counter clockwise will result in a finer grinder
(Fig. 5).
Fig. 5
12
K09639H01 | PROC-CAL/002/03 USER MANUAL | V. 27/09/2023
Once you reach the desired grinding point,
you can lock the grinding regulator using the
regulator brake. ( ) (Fig. 6).
Fig. 6
8. ADJUSTMENT
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.
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.

properly, and produces the highest quality
grind possible, the parts that come into
contact with coee should cleaned
periodically.
General Cleaning guidelines as follows:
• Always turn the main power switch to
the o position ( ).
• Unplug the machine from the power
source.
• Do not submerge the grinder in water
or use power washing devices.
• The appliance is not to be cleaned with
a water jet.
11.2. BEAN HOPPER CLEANING
11. 2.1 In order to properly clean the bean
hopper ( ), first empty out all remaining
beans and fragments.
To remove the hopper, first close the bean
trap ( ), and then loosen the hopper lock
screw ( ) and lift the hopper straight up.
Clean the hopper ( ) with a moist soft cloth
or with a small amount of water and neutral
soap to eliminate any oily residue from the
beans.
Replace the bean hopper ( ) following the
same steps as the removal process, but in
reverse.
11.3. CLEANING THE GRIND CHAMBER
11.3.1 It is recommended that the grind
chamber be cleaned monthly with a
cleaner . This process will eliminate smelly
residues from the coee remains, which can
negatively aect the quality of the brewed
coee.
Care is needed when handling cutting burrs
during cleaning
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 coee in
the grind chamber.
• Pour the recommended grinder
cleaning product into the bean hopper
( ) and open the bean trap
( )
,
allowing the cleaning product to pass
into the grind chamber.
• Grind the cleaning product at a
medium coarse grind setting until
the recommended amount is passed
through the system and nothing
remains in the grind chamber.
• Clean the hopper ( ) and refill with
coee beans.
• Discard the first 2-3 doses of coee 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.

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,
