Before using
Funconing and basic sengs
The grinder models KED640 2.0 and KED640 2.0 HYBRID each have two
grinders that can be controlled separately (leand right).
The shot sizes, i.e. the volume of grounds per withdrawal, are defined by the
grinding me.
The user can specify up to six different recipes (grinding mes) for each of
the grinders (recipe mode) and also has the possibility of controlling the
grinding me manually (manual grinding).
The grinding process is started automacally when the portafilter/grounds
container is inserted and either stops automacally aer the defined grind-
ing me has elapsed (grinding according to recipe) or when the portafilter/
grounds container is removed (manual grinding).
KED640 2.0:
Model KED640 2.0 has two portafilter spaces, i.e. the grounds of both grind-
ers fall directly into the inserted portafilter.
You can modify the KED640 2.0 grinder using a hybrid kit, and as
such, set up a container space instead of a portafilter space (anal-
ogous to model KED640 2.0 HYBRID).
To do this, contact a cerfied service technician who can install
the hybrid kit and unlock the soware menu.
KED640 2.0 HYBRID:
The KED640 2.0 HYBRID model has a portafilter space and a container space,
i.e. the grounds of one grinder fall directly into the inserted portafilter and
the grounds of the other grinder fall into the inserted grounds container (e.g.
for filter coffee).

Seng up the grinder and inserng the bean container
INFORMATION!
Risk of damage!
Improper use can lead to damage of the bean container.
– Make sure during installaon to posion the bean container
in such a way that the locking screw for the bean container
reaches into the appropriate recess of the bean container when
screwing in. If you do not posion the bean container correctly,
you may damage the bean container when screwing in the
locking screw.

KED640 2.0 (HYBRID) | EN
For grinders designed for mains voltage ranges of 200–230 V or
220–240 V, the locking screw for the bean container is a hexagon
socket screw. Use the 2 mm Allen key supplied with this model to
fix the bean container.
For grinders designed for a mains voltage range of 100–127 V, the
locking screw for the bean container is a sloed screw. Use a slot
screwdriver to fix the bean container (not included in delivery).
1. Place the grinder on a level and stable surface that does not vibrate to
prevent it from falling off.
2. Make sure that the rubber ring (23) has been properly posioned in the
bean container intake (2) and is lying flat (see Fig. G).
3. Keep pressing the grinding degree release (5) forward (in the direcon of
the display (14)) and, at the same me, use the grinding degree adjustor (4)
to set the grinding degree to the finest level (scale value “0”) (see Fig. F).
Turn the grinding degree adjustor in such a way that the groove in the
grinding degree adjustor indicates “0” on the grinding degree scale (3).
The locking mechanism can become damaged if you turn the
grinding degree adjustor with force without holding down the
grinding degree release at the same me.
4. Place the bean container (1) onto the bean container intake (see Fig. G).
In doing so, make sure that the pins in the bean container intake catch
the corresponding grooves on the bean container and the recess for the
locking screw on the bean container aligns in the direcon of the locking
screw on the bean container intake.
5. Keep pressing down lightly on the bean container and turn the bean con-
tainer clockwise so that it clicks into the bean container intake.
6. Use a slot screwdriver or the 2 mm Allen key supplied to screw the lock-
ing screw (24) for the bean container clockwise unl finger-ght. Make
sure not to screw the locking screw too ghtly. The locking screw should
be level with the grinding degree adjustor.
7. Repeat steps 2–6 to insert the second bean container into the remaining
(free) bean container intake.
8. Seal the bean container by sliding in both sliding valves (15).
If you do not need both sliding valves, you can clamp them to the
boom of the drip tray (see Fig. E).

9. Place the drip tray (13) into the corresponding opening under the outlet
(6) so that the magnets underneath the drip tray sit in the appropriate
intakes.
Connecng the potenal equalizer
The connecon for potenal equalizaon (19) is located on the back of the
grinder (see Fig. C). The electrical connecon and tesng of electronic func-
onality must be carried out by an electrician.
1. Loosen and remove the lock nut (see Fig. D).
2. Remove the lock ring and the flat washer.
3. Connect the potenal equalizaon conductor (22) to the potenal
equalizer.
The potential equalization conductor is not included with
delivery.
Use a copper potenal equalizaon conductor with a minimum
cross-secon of 10 mm2.
If you have quesons about this, contact an authorized service
partner or electrician.
4. Secure the potenal equalizaon conductor by reaaching the nut, flat
washer and lock ring.
5. Make sure that the grinder is switched off(On/Offswitch (21) to “0”) and
connect the grinder to the power supply by inserng the power plug (20)
into a properly installed safety socket.

Operaon
INFORMATION!
Danger of overheang!
Exceeding the maximum permissible operang cycle can cause the
grinder to overheat.
– Do not exceed the maximum operang cycle
(see chapter “Technical data”).
– Observe the recommended pause when the maximum permis-
sible operang cycle is reached (see chapter “Technical data”).
• The grinder has two fuses that act as an overcurrent
protecon device. If this overcurrent protecon device is
triggered because of electric overload, the grinder’s circuit is
interrupted.
• To be able to operate the grinder once again aer triggering
the overcurrent protecon device, switch the On/Offswitch
(21) to “0” (off) and contact an authorized service partner
(see chapter “Service”).
• The grinder also has a motor protector, which switches offthe
grinder when the motor becomes too hot. As soon as the
motor has cooled down, the grinder can be put into operaon
again (see chapter: “Troubleshoong”).
Adding coffee beans
1. Remove the lid from the bean container (1).
2. Pour whole roasted coffee beans into the bean container from above.
• The maximum filling quanty should be approx. 1 cm below
the edge of the bean container.
• The minimum filling quanty should not fall below 2 cm in
order to ensure that there are no dosing fluctuaons.
3. Place the lid back onto the bean container.
4. If necessary, open the bean container by pulling out the sliding valve (15)
(see Fig. G).
