5. Set-up and Basic Adjustment
5.1 Setting-up Area
Place the grinder on a level surface free from vibration.
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 a power supply system. Proceed as follows:
Protect your device with a separate pre-fuse (not included in the scope of supplies) according to the information provided in para. 2 „Technical data“.
Make sure that the pre-fuse is not overloaded by other consuming devices (e.g. fan-forced heaters, deep
freezers).
Determine whether the mains voltage and frequency
correspond to the information on the rating plate.
Insert the plug into the available grounded outlet.
5.3 Initial operation
A grinding test run is carried out on each grinder in the manufacturer‘s
factory. This is why you may fi nd ground material residue in the grinding
mechanism!

4. Safety devices
Thermal overload circuit breaker (not for 115V/60Hz and 100V/60Hz)
The motor of the grinder is protected by an overload circuit breaker,
which interrupts the electric circuit of the motor when the device is subjected to electric overloading. To be able to re-start the grinder, the reset
button on the back side of the casing must be pressed (Pos.7).
The user has no infl uence whatsoever on this operation. In case of repeated tripping of the circuit breaker, an expert must be consulted since this could cause
damage to the motor winding.
Motor protector (winding shield) (only 115V / 60Hz)
The grinder is protected against thermal overloading by a motor protector (thermostat, inserted in the winding). Whenever the winding of the
motor heats up to an impermissible level, the motor protector interrupts
the electric circuit of the motor.
Following a cool-off phase (approx. 1 hr.), the motor protector is switched
on again automatically and the grinder can be re-started
Finger protector / Magnet holder
A combined fi nger protector / magnet holder is fi tted 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 you should clean the magnet since adhering foreign objects
could be hanging from the magnet.
Never remove the fi nger protection!

Defect
The grinder hums
but does not grind.
7. Operating faults
Cause
The spout is
clogged.
Grinding is set too
fi ne.
A foreign object
is in the grinding
mechanism.
Remedy
Set grinding fi neness to
„coarse“ and trigger the
grinding process. The grinder will then grind itself free.
Afterwards, return the setting to the desired grinding
fi neness.
Turn the grinding fi neness setting to the right,
to „coarse“, and trigger the
grinding process. The grinder will then grind itself free.
Afterwards, return the setting to the desired grinding
fi neness.
Clean the grinding mechanism as described (in para.
9.2) and remove the foreign
object. Observe the safety
instructions!
page 8
Therefore clean the grinder before the fi rst operation with the enclosed
grinder cleaner GRINDZ™. Follow the manual on the instruction leafl et.
6. Operation
1. By moving the rotary knob, set the required grind degree (to the left
for coarse coffee powder, to the right for fi ner coffee powder).
2. Only fi ll unground materials, for which the grinder is set up for, into
the hopper. Close the hopper.
3. Press down the handle of the bag holder (pos. 8) and push the completely opened bag, which has been smoothed along the folds, over
the spout (pos. 3). Let go of the handle and the bag is held fi rmly in
position.
4. Now you can switch on the grinder. Knock the base of the bag a
number of times whilst grinding. This allows the maximum capacity of the bag to be used.
5. When all the coffee has run through hold the base of the bag
loosely in one hand and with the other press the handle of the bag
holder and allow it to knock against the spout 2 or 3 times. This removes any ground coffee powder which may still be attached to the
inside of the spout.
6. Now switch off the grinder and remove the fi lled bag from the
spout.

Defect
The grinder does
not start.
Defect
Grinder rotates but
without grinding.
In case of other malfunctions or continued faults, please contact your
dealer or your authorised customer service centre.
Cause
The power supply
plug is not inserted.
The overload circuit breaker has
been tripped.
The motor protector was tripped.
The pre-fuse was
tripped.
Cause
Carrier breakage.
Metal parts on the
hopper magnet
obstruct the incoming fl ow of material to be ground.
Remedy
Insert the plug into the outlet.
Check to determine whether the reset button of the
circuit breaker has jumped
out. Press the reset button
in again if appropriate. In
case of repeated tripping of
the circuit breaker, contact
your authorised customer
service centre or dealer.
Give the grinder a coolingoff break of approx. 1 hr
(para. 4).
Check the pre-fuse. Restore
the pre-fuse to its initial
state or replace it. Determine whether other consuming devices are also
connected to this fuse.
Remedy
Remove the grinder casing
cover, take out the broken
pieces of the driver, insert a
new driver and then install
the grinder casing cover
again.
Clean the hopper magnet.

Page 10
5. If the adjustment you have made does not come up to your expectations you can adjust the grind degree as described above.
6. Place the rotary knob on the adjusting spindle so that the arrow of
the knob is positioned precisely on the symbol „fi ne“. Clockwise rotation must no longer be possible.
It is important that the rattling sound cannot be
heard in the fi nest grinding position. Otherwise the
service life of the grinding discs is reduced
considerably!
7. Insert the fastening screw of the rotary knob and tighten it fi rmly
with a screwdriver.
If the result is not good enough the grinder needs to be cleaned or you
have to change the grinding discs.
9. Cleaning
Always pull the power supply plug out of the outlet
before carrying out any maintenance or cleaning
work on the device!
Observe the safety instructions under 1.2!
Do not let any foreign objects fall into the grinding
mechanism!

Adjusting spindle
8. Recalibration of the Grind Adjustment
The grinder has been precisely adjusted by the manufacturer. However,
if the ground material is no longer fi ne enough after a longer period, the
grinder must then be re-adjusted according to the following procedure:
1. Use a screwdriver to unscrew the fastening screw in the middle of
the rotary knob and remove the rotary knob.
2. Switch on the grinder.
3. Then rotate the exposed adjusting spindle (see Fig.) very carefully
and slowly in clockwise direction until a slight rattling noise (contact of the grinding discs) can be heard and then rotate the adjusting spindle immediately back again in anticlockwise direction up to
the next notch. It must no longer be possible to hear a rattling noise
of the grinding discs!
4. If you grind some beans now, you should get fi ne grains. If the coffee
beans have been ground too fi ne, the discs can stick together. The
grinder would be blocked.

9.1 Cleaning with GRINDZ™ Grinder Cleaner
We recommend cleaning your shop grinder once a month with our
GRINDZ™ Grinder Cleaner.
Simply take the recommended dose of 70 - 80g and drop it into the empty grinder hopper (2 caps of the jar / 2 sachets).
Adjust the grind setting to coarse and operate as if grinding coffee beans.
Once complete, we recommend passing twice as much coffee through
to purge any residue.
9.2 Cleaning the grinder casing
Clean the casing of your grinder every now and then with commercially
available mild cleaning agents. In addition, you should also clean the
magnet in the hopper from time to time by removing any foreign objects that may have become stuck because otherwise this could result
in clogging.

then remove this cover.
3. Take the carrier (10) out of the slot of the pre-breaker.
4. Pull the pre-breaker (9) off the motor shaft. Use a special puller (art.
no. 4041).
5. Clean the grinding mechanism with a fi ne brush and remove any
foreign objects.
6. Before pushing the pre-breaker (9) back onto the shaft again, lubricate the shaft with non-corrosive, resin-free and foodstuff- compatible grease (e.g. Vaseline).
7. After you have pushed the pre-breaker onto the shaft, line up the
two slots so that you can then easily re-insert the carrier (10).
The round side of the driver must point towards the
motor.
8. Clean the contact surfaces of the grinder casing and grinder casing
cover (12) carefully in order to remove any form of soiling.
