5. Setting-up and Basic Adjustment
A grinding test run is carried out on each grinder in the manufac-
turer‘s 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
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 fol-
lows:
Protect your device with a separate pre-fuse
(not included in the scope of supplies) according
to the information provided in „Technical data“
under 2.
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
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 side of the casing must
be pressed.
The user has no influence whatsoever on this
operation. In case of repeated tripping of the cir-
cuit breaker, an expert must be consulted since
this could cause damage to the motor winding.
Motor protector (winding shield)
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 mo-
tor 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-start-
ed.

LADENMÜHLEN | SHOP GRINDER
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
6.1 How to use the grinder
1. By moving the rotary knob (pos.3), set the required grind de-
gree (to the left for coarse grind, to the right for finer grind).
2. Only fill whole coffee beans (unground material) into the
hopper (pos.1). Close the hopper.
3. Press the handle of the bag holder down (pos.5) and push the
completely 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 (pos.7).
Knock the base of the bag a number of times whilst grinding. This
allows the maximum capacity of the bag to be used.
In the case of the combination grinder, by turn-
ing the combined On / Off - selection switch you
can select the grinder you wish to use.
You can only grind on the side of the grinder
casing side you have selected. You cannot grind
on both sides at the same time.
5. Once all material has been ground, hold the bottom of the
bag gently in one hand. Use the other hand to press the han-
dle of the bag holder and allow it to knock against the spout
2 – 3 times. This removes any ground particles which may
still be attached to the inside of the spout
6. Now switch off the grinder (pos. 8)
7. Remove the filled bag from the spout. The grinding process is
terminated. Close the main hopper slider.

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 inser-
ted.
The overload cir-
cuit breaker has
been tripped.
The motor protec-
tor was tripped.
The pre-fuse was
tripped.
Cause
Carrier breakage.
Incorrect sense of
rotation.
Remedy
Insert the plug into the out-
let.
Check to determine wheth-
er 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 cooling-
off break of approx. 1 hr.
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.

cover, take out the broken
pieces of the driver, insert a
new driver and then install
the grinder casing cover
again.
Have the polarity checked
by specialised personnel.

8. Grind Adjustment Calibration
The grinder has been precisely adjusted by the manufacturer.
However, if the ground material is no longer fine enough after a
longer period, the grinder must then be re-adjusted according to
the following procedure:
1. Turn the rotary knob to position 1 ”fine”. Loosen the two
threaded pins by approx. 1 rotation using the 3 mm hexagon
spanner enclosed in delivery. The two threaded pins are posi-
tioned in the drilled holes of the rotary knob.
2. Now switch on the grinder.
3. Using a screwdriver or coin, carefully turn the large adjust-
ment screw with the slot to the right until you hear a rat-
tling noise (grinding disc are touching). Turn the adjustment
screw back by approx. 10 degrees and the rattling sound
should stop.
4. If you grind some beans now, you should get fine grains (in
the case of coffee). If the coffee beans have been ground
too fine, the discs can stick together. The grinder would be
blocked.
It is important that the rattling sound cannot be
heard in the finest grinding position. Otherwise
the service life of the grinding discs is reduced
considerably!
5. If the adjustment you have made does not come up to your
expectations you can adjust the grind degree as described
above.
9. Cleaning the Grinder
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!!

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 for shop grind-
ers and drop it into the empty grinder hopper. You can also use
the cap of the jar for dosing. A full cap will yield between 35 - 40
grams.
Adjust the machine setting to medium and operate like standard
grinding procedure. Once complete, we recommend passing
twice as much original material through to purge any residue.
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 hopper from time to time.
Do not let any foreign objects fall into the grind-
ing mechanism!!
9.3 Cleaning the grinding mechanism
Pull out the power supply plug !
1. Rotate the rotary knob (11) to „coarse“.
2. Unscrew the two screws (13) on the grinder casing cover (12)
and 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 screw driv-
er. 12

LADENMÜHLEN | SHOP GRINDER
5. Clean the grinding mechanism with a fine 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 food-
stuff- 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 carrier (10).
The rounded side of the driver must point to-
wards the motor.
8. Clean the contact surfaces of the grinder casing and grinder
casing cover (12) carefully in order to remove any form of soil-
ing.
During re-assembly, no ground material should
stick to the surfaces where the grinder casing
and the cover touch.
9. Screw down the cover (12) tightly with the two screws (13)
while changing the side several times.
11. Rotate the rotary knob to the desired grind degree. The grind-
er is now ready for operation again.
Poppy seed grinders shall be cleaned once a week!
10. Maintenance and Repair
Always pull the power supply plug out of the
outlet before carrying out any maintenance or
cleaning work on the device!
Check the device regularly for any signs of dam-
age on the power supply cable, plug, finger pro-
tector, etc.

lowed to be carried out by authorised experts.
Please contact an authorised customer service
centre or your local dealer.
10.1 Grinding Disc Replacement
If the grinding performance decreases and the ground products
are hot and irregular, you should change the grinding discs.
1. Take the grinder apart as described under “9” and remove the
grinding discs from the grinder casing and the pre-breaker
using a screwdriver.
2. Clean the surfaces of the new grinding discs thoroughly and
screw them in position tightly and evenly.
