Always remove the electrical plug from the outlet prior to conducting maintenance or cleaning work on the grinder. Also, prior
to removing the hopper, the plug must be removed from the electrical outlet.
Never operate a grinder with a damaged electrical cord. Inspect
the grinder regularly for damages of the electrical cord, plug, etc.
Any required repairs may only be conducted by authorized service
personnel. For this reason, please contact a customer service repair facility, your dealer or us directly as the manufacturer.
Do not exceed the maximum allowable grinding cycle of S3 25%.
One grinding cycle implies 1/4 grind time and 3/4 rest time for
cooling, e.g. for 1l / 55g / 10s grind need 30s rest (grind cycle of
appr. 40s). Practical restriction: The FCG 2.0 can serve two pourover filter coffee machines. The extraction time of the filter coffee
machines gives enough time for resting.
Do not make any modifications or alterations to the grinder. The
manufacturer assumes absolutely no liability for damages occurring from failure to observe these instructions.
Children cannot appreciate the dangers that can exist in the operation of electrical grinders. For this reason, never leave children
unsupervised with electronic appliances such as this grinder.

5. Set-up of the grinder
A grinding test run is carried out on each grinder in our factory.
This is why you may find ground material residue in the grinding
mechanism!
You have received your grinder in operating condition. Now you
only need to connect the grinder to the mains plug. Proceed as
follows:
5.1 Usage Location
Place the grinder on a level, vibration-free surface. The grinder
is often used in rooms where there is water and humidity, and
therefore it must be properly insulated.
Never operate the grinder in moist, or even
worse, in wet surroundings!
5.2 Electrical connection of grinder
Connect the grinder to an earthed 230V 16A wall outlet.
The machine must be connected to an earthed
power outlet! Always observe the rules in effect
in the user’s country.
4. Safety Devices of the Grinder
Motor protector
The winding of the motor is protected by a thermal switch
(thermo pill/bimetal), which will trip when the motor heats up
significantly. The grinder cannot be started again. Let it rest for
appr. 30 minutes. The thermal switch will re-connect the motor
automatically.
The user has no influence whatsoever on these
circuit breakers. If the circuit breaker trips
repeatedly, an authorised service partner must
be consulted, as the motor’s winding may be
damaged.
Finger protector / Magnet holder
A combined finger protector / magnet holder is fitted in the
hopper of the grinder. It is supposed to prevent the user from
reaching into the running grinding mechanism. At the same
time, it also prevents ferrous foreign objects from getting into the
grinding mechanism. Every now and then clean the magnet since
adhering foreign objects could block the coffee supply.
Never remove the finger protection!

8. Calibration of The Dosing Units
As stated in the overview on page 10, the FCG 2.0 has been calibrated to grind to a coffee-to-water-ratio of 55g/l at a given grind
speed of appr. 5.5 g/s.
Depending on:
• the origin of the coffee,
• the type of coffee (arabica, robusta, etc. ),
• the size of beans,
• the blend,
• the degree of roasting,
• the cooling method after roasting (i.e. moisture content of
the bean),
• the age of the roasted coffee,
• the cleaning status of the grinder,
• other external influences (humidity, temperature, etc.)
• and most importantly: the adjusted grind size
the grind speed of the FCG 2.0 can vary quite drastically (5g/s up
to 8g/s).
Subsequently the dosed amount e.g. per cup of an individual
coffee at its best grind size does not match the aimed-for 55g/l.
The actual grind speed of the FCG 2.0 for the chosen coffee has
to be adjusted in the software to ensure the perfect coffee-towater-ratio.
8.1 Grind a preset amount of coffee
With coffee in the hopper place a tared cup under the spout and
press the START-button (pos.8) for 6 seconds. The grinder will
start grinding for exactly 10 seconds. The display will show CA for
“calibration”.
Weigh the ground coffee.
8.2 Enter the correct amount of coffee
The display will show a number (factory setting 55). Using the
+/-buttons enter the correct weight of the coffee that has been
ground in 10 seconds.
The software will automatically adjust the grind times to match
the perfect coffee-to-water-ratio of 55g/l.
8.3 Quit the calibration mode
To leave the calibration mode press the START-button (pos.8) for
6 seconds.
8.4 Changing the coffee-to-water-ratio (g/l)
In order to change the factory setting of 55g/l (SCAE Gold Cup
Standard) use the following formulae to calculate the value that
has to be typed into the grinder (see 8.2).

10. Cleaning
You should clean your filter coffee grinder regularly, just like your
brewing machine. Grind-on-demand grinders in particular have
to be kept clean and residue free in order to ensure dosing accuracy for every shot and every customer.
10.1 Cleaning with GRINDZ™ grinder cleaner
We recommend cleaning your filter coffee grinder every 1-2
weeks (every 15 kg) with our GRINDZ™ Grinder Cleaner.
The display will show “GRINDZ” when 15 kg were ground with no
influence on the standard operation. To reset this cleaning alarm
see chapter 7.3.
For cleaning your grinder with GRINDZ™, just follow the steps below:
• Run the grinder empty of beans
• Fill 70 grams of GRINDZ™ directly into the hopper (content of
two sachets or two can lid).
• Adjust the grind size to coarse (for a better cleaning effect of
the GRINDZ™-particles).
• Start the grinder and grind through all GRINDZ™ into your
brew basket or a seperate bin.
• Grind appr. 2 - 3 sec. of coffee in order to purge the residues of
GRINDZ™ out of the disc casing.
Formation of dust while grinding GRINDZ is
natural and harmless. The dust particles can be
cleaned with a soft cloth from the casing and
spout.
10.2 Cleaning the grinder placement surface
Pull out the mains plug!
• Lift the grinder aside and clean the area on which it stands and
the bottom of its base.
• Both surfaces must be dry and free of oil and grease.
• Reposition the grinder and re-insert the plug.
10.3 Cleaning the grinder casing
From time to time clean the outside of the casing using a damp
cloth with a liquid non-abrasive detergent.
10.4 Cleaning of the hopper
The hopper should be cleaned weekly with a damp cloth inside
in order to remove coffee and oil residues which could negatively
influence the taste in the cup.
14
Page 15
11. Service
