8 Operation
Prepare the hopper by placing it on the grinder and turning it clockwise
until it fits in place. Remove the hopper lid (1), fill the hopper (2) with
coffee, close the lid and open the hopper opening. Fig.1. If the hopper is not
correctly fitted, a warning message with appear on the display.
Connect the machine to the power supply; turn it on using the ON-OFF
switch located on the bottom part of the grinder (11). Select the desired
grinding point using the endless regulator (tightening it for a finer grind and
loosening for thicker grind).

Fig. 2.
Place the portafilter under the discharge tube. The amount of coffee
dispensed per serving will depend on the grinding point (adjustable with
the endless regulator) and the grinding time (see point 2 of the menu
structure).
The grinder has 3 operating modes that you can choose from point 1
on the menu:
a) Automatic with pre-dosis. The dispenser has 2 chambers that hold
two pre-ground servings. The grinder will dispense one or two servings
based on the number of pushes made. The grinder then automatically
grinds as many servings as those dispensed in order to maintain the 2
chambers with ground coffee.
b) Automatic. The doors of the chambers can be open so that the
serving(s) selected is(are) ground and dispensed instantly, with the
grinding time selected in point 2 of the menu.
c) Manual. The dorrs of the chambers can be open so that the grinder
grinds and dispenses instantly, with the grind time being the amount of
time we wait between the first and second push.

i
NOTE: If the coffee comes out slowly, this is because the coffee is set
to grind very fine. If it 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.

9 Cleaning
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 (11).
• Disconnect the machine from the power supply.
• Do not submerge the machine in water.
9.2. Cleaning of the coffee bean hopper
Before cleaning, make sure that there are no beans left in the hopper
(2). Close the hopper opening lever, turn it counter-clockwise until it
comes off the grinder. Clean it with a damp cloth or soap and water to
eliminate the oil residues from the coffee, washing it carefully and then
drying. Replace the hopper and turn it clockwise back into position, Fig
1. If it is not correctly positioned, a warning message with appear on
the display.
9.3. Cleaning the coffee discharge tube
To clean the coffee discharge tube, select (point 1.3) CLEANING from
the menu and make sure that the upper and lower lids are open. With
the help of a brush, clean the remains of coffee that may be stuck to
the inside of the dispenser chambers. Lastly, close the lids in point 1.2.1
and 1.2.2 of the menu.
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. If you do NOT
follow these instructions, it could affect the taste and aroma of the
coffee.

10 Maintenance

i

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 (11).
• 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. Especially, the usage level of the burrs which sholud be
systematically checked.The perfect conditions of the burrs guarantees
an even grind of the coffee and an 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 according to the
following table:
Model
A-8

Kg/lb of ground coffee
400 Kg/880 lb

10.3. Changing the burrs
To change the burrs, please follow these indications:
1 - Turn off the machine using the ON-OFF switch (11).
2 - Disconnect the machine from the power supply.
3 - Close the hopper opening and lift off the hopper (2) (fig. 3).
4 - Take apart the endless regulator by loosening the grind lock
(fig. 4), previously explained in general warnings.

5 - Remove the upper cover, unscrewing the five upper screws
using an Allen wrench, (fig. 4) (Do not pull hard or you could damage
the on-off switch cables).
6 - Take off the silicone covering from the upper burr holder
(fig. 5).

15 - Screw on the upper crown wheel.
16 - Replace the silicone cover. Screw on the upper covering.
17 - Replace the endless regulator and grind lock. Replace the hopper
turning it clockwise.
18 - Go to point 2.5.1. of the menu to configure the reset to zero
after the burr change. This is the point where the burrs no longer
touch one another.

11 Safety measures
Fig. 3

Fig. 4

Fig. 5

7 - Unscrew the three fixing screws from the crown wheel (fig. 6).
8 - Completely remove the upper burr tray from the cup and take
out the upper burr (fig. 7).
9 - Turn the nut on the motor axle in a clockwise direction.
Preferably with a socket wrench. Hold the lower burr tray in place
using a tool in order to avoid it turning when loosening the nut. Be
careful to not damage any component (fig. 8).
10 - Clean off coffee residue from the screws on the lower burrs
(fig. 8).
11 - Unscrew the 3 screws on the lower burr, continuing to hold the
lower burr holder in place to avoid it turning.
	
a.To remove the lower burr holder: take out the 3 screws
on the burr by unscrewing them in sequence and pushing down on
the cup so that the pressure works to lift it up from the motor
axle.
12 - Before putting in the new burrs, make sure both burr holders
are residue-free in order to not affect the parallelism between
them.
13 - Put in the new burrs.
14 - Turn the upper burr holder in the cup until the burrs touch.

The grinder incorporates a safety mechanism to stop grinding when the
hopper (2) is removed.
NOTE: The manufacturer cannot accept responsibility for any damage
caused by improper use of the machine or failure to respect the safety
measures indicated above.
Users are asked to pay careful attention to the following indications:

i

• The coffee grinder should only be used for grinding coffee beans.
• Do not use the machine to grind other types of foods such as nuts,
dried fruits or to fine-grind granulated foods such as sugar, etc.
• Do not allow minors or disabled people to use the machine.

!

• Any other use of the machine will be considered improper and
dangerous.
• Do not allow liquids to come into contact with the internal or
external surfaces of the machine at any time, except for those parts
that have been expressly referred to in the “CLEANING” section.
If, for any reason, this should occur, immediately disconnect the
machine from the power supply and dry all surfaces carefully. Should
it be necessary to access the internal parts of the machine, where
the electrical components are located, take the machine to your local
technical service.
• In the event of any broken components or intervention, we
recommend that you contact your local technical service, who will
repair or replace the part, guaranteeing the maintenance of the safety
standards.
• Replacement of the main power cable of any Compak grinder can
only be carried by Compak or an authorized supplier.
