Intended use
The grinder is designed to grind whole roast coffee beans.
If necessary, the grinder can be used to grind other foods, such as certain types
of grain.
Contact your retailer for informaon on this. The grinder should only be used
to grind the materials for which it has been designed. In general, make sure
that only cleaned, unground material is used. Do not use the grinder to grind
other products or objects.
The grinder is intended for commercial use but is not suitable for connuous
high-volume producon. The grinder may only be maintained by trained
personnel. However, it may be operated by other persons in a place where
use is supervised.
Any other use is considered improper and can result in material damage or
even personal injury. Do not make any modificaons to the grinder. Neither
the manufacturer nor the retailer can accept liability for any injury or damage
resulng from failure to comply with the safety informaon.
Safety informaon

3. Check for damage to the grinder or any of the individual parts.
If there is any damage, do not use the grinder. Contact your retailer (see
“Maintenance and service” secon).
Please note that the grinder has undergone a comprehensive
funconal test prior to delivery and may contain ground coffee
residue.
Seng up the grinder
The grinder’s power cable (14) can be moved to any side of the
grinder and posioned between two of the feet (13) to suit the
area in which the grinder has been set up, or the availability of a
socket.
1. Place the grinder on a level and stable surface that does not vibrate.
2. Make sure that the rubber ring (16) has been properly inserted into the
bean hopper intake (2) and is lying flat
(see Fig. D or E).
3. Posion the bean hopper (1) on the bean hopper intake.
In doing so, make sure that the pins in the bean hopper intake engage with
the corresponding guides on the bean hopper.
4. Rotate the bean hopper clockwise to lock it in place on the grinder.
5. Insert the power plug (14) into a properly installed wall socket.
6. Push the spill tray (6) into the corresponding opening under the spout (7).

Connecng the potenal equalizaon
The connecon for potenal equalizaon (12) 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. F).
2. Remove the lock ring and the flat washer.
3. Connect the potenal equalizaon conductor (17) to the potenal equalizer.
• The potenal equalizaon conductor is not included with the
delivery.
• Use a copper potenal equalizaon conductor with a mini-
mum cross-secon of 2.5 mm2(shielded) or 4 mm2(unshield-
ed).
• If you have quesons about this, contact an authorized service
partner or electrician (see “Maintenance and service” sec-
on).
4. Secure the potenal equalizaon conductor by reaaching the nut, flat
washer, and lock ring.

Operaon
NOTE!
Risk of damage!
The operator cannot adjust the thermal overcurrent circuit-breaker.
If the thermal overcurrent circuit-breaker has been triggered several
mes, a service partner must be contacted for advice, as the motor
winding can become damaged.
• The grinder has a thermal overcurrent circuit-breaker which
interrupts the electric circuit of the grinder in the event of an
electrical overload. To put the grinder into operaon again, for
the EK43, EK43 Sfirst press the offswitch 0(4). For the EKK43
turn the rotary switch to (19) posion 0 (off). Disconnect the
power plug (14) and then push the release buon (15) in. You
can now plug the power plug back into the socket and operate
the grinder (see “Seng up the grinder” secon).
• 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 “Troubleshoong” secon).
Adding the coffee beans
1. Remove the lid of the bean hopper (1).
2. Pour whole roasted coffee beans into the bean hopper from above.
• The maximum fill amount should be approx. 1 cm below the
edge of the bean hopper.
3. Place the lid back onto the bean hopper.
4. If necessary, open the bean hopper by pulling out the slider (11) (see Fig.
D and E).

19
EK43 | EK43 S| EKK43 | EN
Switching on the grinder and adjusng the grinding degree
• The pointer on the hand wheel (9) displays the current grind-
ing degree on the grinding degree scale (10).
The finest seng is “0” and the coarsest seng is “16”.
• Only reduce the grinding degree when the grinder is in opera-
on.
• To avoid/eliminate imbalances when seng the grinding de-
gree, it is advisable to first set the grinder to a coarser grinding
degree (about one degree/unit above the desired grinding
degree) and to subsequently reduce the grinding degree to
the desired fineness using the grinding degree slider.
1. Make sure that the power plug (14) is inserted into a properly installed socket
and that the slider (11) encloses the bean hopper (1) in the direcon of the
grinding mechanism.
2. Switch on the grinder (for EK43, EK43 Sby pressing the On switch I(3),
for EKK43 by seng the rotary switch (19) to posion 1or 2).
3. Rotate the hand wheel (9) clockwise or counterclockwise unl the pointer
displays the desired grinding degree on the grinding degree scale (10) (see
Fig. G). Turn the hand wheel toward “0” for fine coffee grounds and in the
opposite direcon for coarse coffee grounds.
Clamping the coffee bag or grounds container
1. Hold down the lever (5) for the bag clamp.
The bag clamp (8) will rise up around the sides of the spout (7) (see Fig. H).
2. Put a coffee bag over the spout or posion a suitable grounds container
underneath it.
• Due to its height, the EK43 Smodel is not designed for bag grind-
ing. Use a suitable grounds container instead (not included with
delivery).
• When clamping a grounds container that is made of conducve
material, make sure that the grounds container rests against the
contact strips (18) on the back of the spout. This reduces the
electrostac charge of the ground coffee.
3. Release the lever.
The bag clamp will close around the spout and hold the coffee bag or
grounds container in place.
4. Connue to the “Starng the grinding process” secon.

20
COMMERCIAL COFFEE GRINDER
Starng the grinding process
1. Start the grinding process (for EK43, EK43 S by pressing the On switch I (3),
for EKK43 by seng the rotary switch on the grinding mechanism (19) to
posion 1or 2, whichever you wish to use to grind your beans).
2. Pull out the slider (2) to open the bean hopper on the end facing the
grinding mechanism (see Fig. D or E).
The grinder will grind the filled volume of coffee beans.
3. The grinding is completed as soon as the grinder is idle and grinding
noises cannot be heard.
• The EKK43 model cannot operate with both grinding mecha-
nisms simultaneously. Adjust the rotary switch on the grind-
ing mechanism (posion 1or 2) that you want to use for the
process.
Changing the grinding mechanism
1. If you want to switch from one grinding mechanism to the other for the
EKK43 model, turn the rotary switch to posion 0.
Allow the motor on the grinder to come to a complete stop.
2. Turn the rotary switch to posion 1or 2 to start the grinding process.
Proceed as described in point 2 and 3 of the “Starng the grinding pro-
cess” secon.
Aer the grinding process
1. Close the bean hopper (1) by pushing in the slider (11).
2. Using one hand, steady the coffee bag or grounds container and let the
knocker (8) tap against the spout a few mes using the lever (5) to shake
any residual grinds out of the spout (see Fig. I).
3. Hold down the lever and remove the coffee bag or grounds container
containing the ground material from the spout (7).
4. Switch offthe grinder (for EK43, EK43 Sby pressingthe Offswitch 0(4),
for EKK43 by seng the rotary switch (19) to posion 0).
Changing the coffee variety
1. Close the bean hopper (1) by pushing in the slider (11).
2. Grind the coffee beans lein the grinding mechanism unl the grinder
runs empty.
