5. Setting-up and Basic Adjustment
A grinding test run is carried out on each grinder in the factory.
This is why you may find ground material residue in the grinding
mechanism!
5.1 Setting-up area
Place the grinder on a level surface free from vibration.
Never operate the grinder in moist, or even wor-
se, 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 fol-
lows:
Protect your grinder with a separate pre-fuse
(not included in the scope of supplies) according
to the information provided under Item 2 „Tech-
nical data“.
Make sure that the pre-fuse is not overloaded
by other consuming devices (e.g. fan-forced
heaters, deep freezers).
4. Safety devices
Thermal overload circuit breaker
The motor of the grinder is protected by an overload circuit brea-
ker, which interrupts the electric circuit of the motor when the
grinder 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.8).
The user has no influence whatsoever on this
operation. In case of repeated tripping of the
circuit breaker, a service technician must be
consulted since this could cause damage to the
motor winding.
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 you should clean the
magnet since adhering foreign objects could be hanging from
the magnet.
Never remove the finger protection!

The bag is shaken by this shaking panel. Do not hold the bag
during the grinding process so that it is positioned against
the shaking panel fully opened.
5. After all coffee has been ground hold the base of the bag
loosely in one hand and with the other hand press the handle
of the bag holder and allow it to knock against the spout 2 or
3 times. This removes any ground coffee which may still be
attached to the inside of the spout.
6. Now switch off the grinder and remove the filled bag from
the spout.
Determine whether the mains voltage and fre-
quency correspond to the information on the
rating plate.
Insert the plug into the available grounded outlet.
6. Operation
1. Position the grind adjustment lever of the grind degree set-
ting to the grind degree you require (Pos. 3).
2. Only fill whole coffee beans into the hopper. Close the hop-
per.
3. Press down the handle of the bag holder and push the com-
pletely opened bag, which has been smoothed along the
folds, over the spout. Let go of the handle and the bag is held
firmly in position.
4. Now you can switch on the grinder and the grinding process
starts. The grinder is equipped with a shakingpanel to make
sure that ground coffee cannot clog the spout.

Defect
The grinder hums
but does not grind.
7. Operating Faults
Cause
The spout is
clogged.
Grinding is set too
fine.
A foreign object
is in the grinding
mechanism.
Remedy
Set grinding fineness to
„coarse“ and start the
grinding process. The grind-
er will then grind itself free.
Afterwards, return the set-
ting to the desired grinding
fineness.
Turn the grinding fine-
ness setting to the right,
to „coarse“, and start the
grinding process. The grind-
er will then grind itself free.
Afterwards, return the set-
ting to the desired grinding
fineness.
Clean the grinding mecha-
nism as described (see 9.3)
and remove the foreign
object. Observe the safety
instructions!
Defect
The grinder does
not start.t
Cause
The power supply
plug is not insert-
ed.
The overload cir-
cuit breaker has
been tripped.
The pre-fuse was
tripped.
Remedy
Insert the plug into the out-
let.
Check to determine wheth-
er the reset button of the
circuit breaker has jumped
out (pos.8). Press the reset
button in again if appropri-
ate. In case of repeated trip-
ping of the circuit breaker,
contact your authorised
customer service centre or
dealer.
Check the pre-fuse. Restore
the pre-fuse to its initial
state or replace it. Deter-
mine whether other con-
suming devices are also
connected to this fuse.

LADENMÜHLEN SHOP GRINDERS
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
Metal parts on
the hopper mag-
net obstruct the
incoming flow
of material to be
ground.
Remedy
Clean the hopper magnet.
8. Recalibration of the Grind Adjustment
The grinder has been precisely adjusted by the manufacturer.
However, if the ground coffee is no longer fine enough after a
longer period, the grinder can be re-adjusted according to the fol-
lowing procedure:
1. Move the grind adjustment lever into position “1”.
2. Unscrew the three hopper attachments and remove the hop-
per.
3. Now switch on the grinder.
4. Looking into the upper part of the casing you will see a red
hexagon screw at the back on the adjusting ring. Loosen this
screw using an 8 mm fork wrench. Now move the grind ad-
justment lever to position “5”and tighten the hexagon screw
again.
A: red hexagon screw
B: adjusting ring

LADENMÜHLEN SHOP GRINDERS
5. Now carefully move the grind adjustment lever in the direc-
tion of position „1” until you hear a rattling noise, then im-
mediately turn it back by 1 or 2 notches. The rattling sound
is created by the grinding discs coming into contact with one
another and may only be caused for a very brief moment as
otherwise the teeth can be damaged.
6. Now loosen the red hexagon screw again and move the grind
adjustment lever to position „1“ and tighten the red hexagon
screw again. Make sure that the adjusting ring is set correctly.
It is important to ensure that no „rattling“ noise
of the grinding discs can be heard! Their service
life will otherwise be significantly reduced!
7. Put the hopper back on again and screw in the three hopper
attachments through the upper part of the casing and into
the threads of the hopper.
If the result is not good enough the grinder then needs cleaning
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 grinder!
Observe the safety instructions under 1.2!
Do not let any foreign objects fall into the grin-
ding mechanism!!
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. You can also use the cup of the jar for
dosing. A full cup will yield between 35 - 40 grams.
Adjust the grind setting to medium and operate as if grinding
coffee beans. Once complete, we recommend passing twice as
much coffee through to purge any residues.

9.2 Cleaning the grinder casing
Clean the casing of your grinder every now and then with com-
mercially available mild cleaning agents. In addition, you should
also clean the magnet in the hopper from time to time by remo-
ving any foreign objects that may have become stuck because
otherwise this could result in clogging.
Do not let any foreign objects fall into the grin-
ding mechanism!!
9.3 Cleaning the grinding mechanism
Pull out the power supply plug !
1. Move the grind adjustment lever to position “9”.
2. Remove the cladding by tapping it slightly in the direction of
the arrows.
3. Now you can open both quick release locks and remove the
upper part of the casing as well as the hopper.
Grinder casing fro the top:
a) grinding disc
b) grinding space
c) drilled hole with safety switch inside
d) surface of the grinder casing
e) quick release locks
Grinder casing cover with hopper:
f) grinding discs
g) grinder casing cover
h) surface of the grinder casing cover
i) screw for safety-switch
4. You can clean the grinding space with a hard brush now.
Ground coffee can be left in the grinding space. The spout is
cleaned from below.
No coffee residues may adhere to the surfaces
where the grinder casing and the grinder casing
cover lie on top of one another when you put
the grinder back together again.

5. Put the upper part of the casing back on and close the quick
release locks. Make sure that the screw in the grinder casing
cover engages in the hole in the grinder casing.
There is a safety switch underneath this hole which prevents
the grinder being switched on accidentally when the upper
part has been removed.
6. Now push the cladding back onto the upper part of the ca-
sing.
Move the grind adjustment lever to the coarsest
setting on the right.
Plug the plug into the socket and switch the grinder back on
again. The coffee remains in the grinding space are now th-
rown out, therefore position a bag or a container under the
spout.
7. Now move the grind adjustment lever back into notch “1”
and the grinder is ready for grinding again.
10. Maintenance and Repair
Always pull the power supply plug out of the
outlet before carrying out any maintenance or
cleaning work on the grinder!
Check the grinder regularly for any signs of da-
mage on the power supply cable, plug, finger
protector, etc.
Any repairs that may be required are only al-
lowed to be carried out by authorised experts.
Please contact an authorised customer service
centre or your local dealer. 10.1 Grinding Disc
Replacement
10.1 Grinding disc replacement
If the grinding performance decreases and the ground coffee is
hot and irregular, you should change the grinding discs.
1. Open the grinder as described in “9.3 Cleaning the grinding
mechanism”.
2. After removing the old grinding discs, coffee residues must
be cleaned from the seat and surfaces of the grinding discs
before the new grinding discs can be inserted.
13

||
LADENMÜHLEN SHOP GRINDERS
If this is not done, the grinding discs are not parallel to one
another and the ground coffee would be coarse and uneven.
3. Make sure that the surfaces are very clean when you place
the upper part of the casing in its position. Proceed as descri-
bed in “9.3”.
4. If the machine needs to be readjusted, proceed as de scribed
in „8. Recalibration of the Grind Adjustment“.
