4. Safety Devices of the Grinder
Thermal overload circuit breaker
The motor of the grinder is protected by a thermal overload circuit
breaker, which interrupts the motor's electric circuit in the event of
electric overload. The trip switch, item 19, must be pressed to
enable the grinder to be re-started.
The user has no influence whatsoever on
this circuit breaker. If the circuit breaker
trips repeatedly, an authorised service
partner must be consulted, as the motor's
winding may be damaged.

5. Set-up and Basic Adjustment
A grinding test run is carried out on each grinder in the
manufacturer's factory. This is why you may find ground material
residue in the grinding mechanism!
5.1 Usage Location
Place the grinder on a level, vibration-free surface.
Never operate the grinder in moist, or even
worse, in wet surroundings!
5.2 Installation
You have received your grinder in operating condition. Now you
only need to connect it to the mains. Proceed as follows:
Protect your device with separate pre-fuses
(not included in the scope of delivery) according
to the information provided under Point 2 "Tech-
nical data".
Make sure that the pre-fuse is not overloaded
by other devices (e.g. fan heaters, deep freez-
ers).
Check whether the mains voltage and frequency
correspond to the information on the rating
plate.
Insert the plug into the corresponding grounded outlet.
5.3 Basic Adjustment
Once the device is ready to operate, a grinding test should be
carried out.
Basic adjustment to a moderately fine setting has been carried out
in the factory using espresso beans. The following markings have
been made on the grinding mechanism (interior):
Red line: Basic adjustment 0, finest setting and minimum
grinding disc spacing
Red line: Basic factory setting and also the position for
installing and removing the lid, in order to
achieve the factory setting after positioning
the lid.
Never rotate the grinding discs clockwise up
to the red mark, as the grinding discs may
otherwise be damaged.

6. Operation
Only use the K 30 ES espresso grinder according to the purpose
specified in 1.3.
Observe the safety instructions under 1.2!
Never exceed the maximum permissible continuous operating
period of running time (S3 20% e.g. 4 sec on and 16 sec off); 6 sec
on and 60 sec off only for 115V/60Hz. Do not exceed the
maximum allowable continuous grinding time of 20 min
Afterwards, allow the grinder to cool off before the next operation.
6.1 Handling the Grinder
Proper operation necessitates the steps described in the following:
6.1.1 Actuate the main switch on the rear of the device. Set the
grinding fineness e.g. to 2 ½.* To do this, pull the sliding detent,
item 3, out to the front and turn the lid / grinding fineness adjust-
ment to the left to the 2 ½ mark.
Rotation to the left = fine
Rotation to the right = coarse
6.1.2 Open the bean container. Pour whole, roasted espresso
beans into the bean container from above. Never pour in coffee
powder.
6.1.3 Check whether the hopper slide (item 18) is open.
6.1.4 Adjust the filter support rest (item 14) to your espresso
machine's filter support. Proceed as follows:
Switch the K 30 ES espresso grinder off using the main switch
(item 19). Use the enclosed Allen key to loosen the fastening
screws (item 15) slightly and adjust the height of the filter support
rest.
If the enclosed filter support rest does not
fit, please contact the manufacturer or your
local dealer. We will be happy to send you
a different rest.
Slide the filter support between the filter support mounting and the
filter support rest until it comes to a stop.
Push the filter support rest up and tighten the fastening screws.
The setting is correct when the filter support independently
remains in the mounting.
6.1.5 Check whether the factory grinding time settings for single
S 2.0 and double D 4.0 appear in the display. If the display corre-
sponds to the factory settings, continue as described in point 6.1.9;
if this is not the case, the time must be set (see point 6.1.6).

6.1.10 Push your espresso machine's filter support into the filter
support mounting, item 13, until the grinding process is switched
on.
6.1.11 Now make a test portion of espresso using your machine.
If the result is unsatisfactory, repeat adjustment steps 6.1.6 to
8.1.8 again by varying the grinding time and grinding fineness.
Carry out this process until the best coffee results have been
reached.
6.2 Display / Menue

the filter support back into the mounting. The missing quantity is
ground into the filter support.
If this is not desired, the pre-selection button can be activated
and the entire set grinding quantity or grinding time is available
once again.

7. Operating faults
In the case of other malfunctions or continued faults, please
contact your dealer or your authorised customer service
centre.
8. Cleaning
8.1 Cleaning with GRINDZ™ Grinder Cleaner
We recommend cleaning your espresso grinder once a week and
your shop grinder once a month with our GRINDZ™ Grinder
Cleaner.
Simply take the recommended dose (35 - 40g for espresso
grinders and 70-80g for shop grinders) and drop it into an empty
grinder hopper. You can also use the cup of the jar for dosing. A
full cup will yield between 35 - 40 grams.
Adjust machine setting to medium and operate as if grinding
coffee beans. Once complete, we recommend passing twice as
much coffee through to purge any residue.
8.2 Cleaning the Grinder Placement Surface
8.2.1 Pull out the mains plug!
8.2.2 Tilt the grinder to one side and clean the area on which it
stands and the bottom of its base.
8.2.3 Both surfaces must be dry and free of oil and grease.
8.2.4 Replace the grinder
Defect
The grinder
does not
start, the
operating mode
display is not lit.
Cause
The mains plug
is not inserted.
The overload
circuit breaker
has been
tripped.
The pre-fuse has
tripped.
Remedy
Insert the mains plug into the
socket.
Check to determine whether
the trip button of the circuit
breaker has jumped out.
Press the trip button in again
if appropriate. If the circuit
breaker trips repeatedly,
contact your authorised
customer service centre or
dealer.
Check the pre-fuse. Restore
the pre-fuse to its initial state
or replace it. Determine
whether other devices are
connected to this fuse.
