Connect the machine to the power supply, press the On-Off
switch (14 Elite -10 Touch position 2) and open the shutter (4)
to let the coffee through. Remove the dispenser lid (8) and turn
the grind regulator (6) to the required grind setting. By turning it
clockwise, the coffee grind will be coarser and turning it counter-
clockwise, the grind will be finer. Note that you should only change
grind settings when the machine is on and burrs are in motion.
If you do not do this, the burrs will gunk up and cleaning will be
required. Changing the grind settings when the burrs are not in
motion will cause the grinder to only make very coarse grinds or
no grinds at all. Fig. 3.
Remove the hopper lid (1), fill the hopper (2) with coffee and
replace hopper lid. Fig. 2.
7.1. Preparing the coffee grinder
Place the hopper (2) on the grind regulator (6) and check that the

For security reasons the regulator is limited to a single turn.
In the Stepped models, the grinding positions are set by the place-
ment of the holes shown in the photo. Using these holes, select the
grind point you desire. Fig. 4.
NOTE: If a lot of coffee comes out slowly, this is because the
coffee is set to grind very fine. If a little comes out very fast, it
is because the grind is very thick.A perfect espresso is achieved
with a grinding point of 25 ml of coffee brewed in 25 seconds.

7.2. Regulating the coffee servings K-3 & K-3 Elite
The dispensers are factory adjusted to serve an amount of
approximately 7 gr of ground coffee, but this quantity can be
regulated between 6 and 10 gr, as follows: Remove the ground
coffee dispenser lid (8) and turn the dispensing regulation screw
(9) clockwise to obtain a smaller amount of coffee, and counter-
clockwise to obtain a larger amount. Once the quantity of each
serving has been regulated, replace the ground coffee dispenser
lid (8). Fig. 5.

8Operation
8.1. Using the K-3 & K-3 Elite
To turn the machine on and off, use the On-Off switch (14).The
machine will start to grind the coffee. If the automatic stop option
is incorporated, the grinder will stop grinding when the dispenser
reaches the maximum level, and will restart after 8 portions of
coffee have been served, grinding again to the maximum level. If
the machine does not incorporate the automatic stop option, we
recommend that you fill the doser 75% of its capacity in order to
guarantee consistent dosing.
To serve the coffee servings, place the portafilter on the support
crutch (13) as far in as possible so that it is positioned under the
ground coffee discharge tube. Pull the dispensing handle (11) to
obtain one coffee serving (one serving is equal to one cup of
coffee), and release it so it returns to its normal position. Fig. 7.
Take the portafilter and place it under the coffee tamper (12),
pressing upwards to pack the coffee. Fig. 8.
Fig. 7
7.3. Coffee regulation for the K-3 Touch
The K-3 Touch model grinding time is factory regulated to serve
portions of approximately 7 g.To change the grinding time, turn off
the machine using the 3-position switch (10).
Turn the plastic axle located on the underside of the machine. If
turned clockwise, the quantity of coffee will be increased and if
turned counter-clockwise, the amount will be reduced. Fig. 6.
Turn the 3-position switch to position 1. Check that the amount of
ground coffee is correct. If not, repeat the operation.
Fig. 6

8.2. Using the K-3 Touch
The K-3 Touch model has 2 operating positions:
Switch in position 1: Grinds individual coffee servings.
Switch in position 2: Grinds coffee continuously until the switch is
changed back to 0.
Fig. 10
In position 1, press the front push lever once with the portafilter
(8), rest it on the support crutch (9) and a single serving of freshly
ground coffee is obtained, and by pushing twice, the serving will
be double. Fig. 10.
9Cleaning
9.1. General cleaning
To guarantee the correct operation of the machine as well as the
quality of the ground coffee, we should periodically clean the parts
that come into contact with the coffee (at least once a week).
Before performing any type of maintenance work, the following
indications must be taken into consideration:
• Always turn off the machine using the On-Off switch (14 Elite
-10 Touch).

10.1. General warnings
Before performing any type of maintenance work, the following
indications should be taken into consideration:
• Always turn off the machine using the On-Off switch (14 Elite
-10 Touch).
• Disconnect the machine from the power supply.
In the event of a breakdown or malfunction, turn the machine off.
Do not try to repair it or intervene directly. Please call your local
technical service.
NOTE: Failure to respect this warning could endanger the
safety of both the machine and user.
10.2. Regular maintenance
To guarantee the efficiency and correct operation of the grinder,
it is essential to follow manufacturer instructions and ensure that
all maintenance work is carried out by qualified staff. Regular,
programmed inspections are recommended of the parts subject
to wear and tear. Systematically check the usage level of the burrs.
The perfect condition of the burrs guarantees an even grind of
the coffee and optimum quality of the product served. It also
reduces electrical consumption and the risk of the motor and
burrs overheating.
NOTE: Based on extensive experience and a medium-hard
coffee blend, we recommend replacing the burrs after grinding
300 Kg/660 Lb of coffee.
Maintenance
• Disconnect the machine from the power supply.
• Do not submerge the machine in water.
• We recommend the use of cleaning tablets to remove excess
grounds.

hopper (2).
Loosen by hand the setting roller (5) and remove the coffee bean
hopper (2) from the grind regulator (6) as in Fig.1 and clean it with
a damp cloth or soap and water to eliminate the oil residues from
the coffee, washing it carefully and then drying.
Put the hopper back on the grind regulator (6) and adjust the
setting roller (5) by hand.
9.3. Cleaning the ground coffee deposit
To clean the ground coffee holder, first empty all the coffee inside
it. Remove the ground coffee dispenser lid (8) and clean the inside,
using a small brush.
9.4. Exterior cleaning
To clean the exterior, use a brush or a cloth dampened with a little
bit of soap and water.
NOTE: Never use damp clothes to clean the coffee deposit.
Conserve the brush in a protected place and only use it to
clean the grinder to avoid it being contaminated from other
substances. Not following these instructions could affect the
taste and aroma of the coffee.
