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 influence 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)
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 (at least 100 minutes) the motor protector is switched on again automatically and the grinder can be re-started
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!
(only 115V / 60Hz)
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 find ground material residue in the grinding mechanism!
page 7
Page 8

Therefore clean the grinder before the first operation with the enclosed grinder cleaner GRINDZ™. Follow the manual on the instruction leaflet.
6. Operation
1. By moving the rotary knob, set the required grind degree (to the left for coarse coffee powder, to the right for finer coffee powder).
2. Only fill 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 firmly 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.
7. Operating faults
Defect
The grinder hums but does not grind.
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 trigger the grinding process. The grind­er will then grind itself free. Afterwards, return the set­ting to the desired grinding fineness.
Turn the grinding fine­ness 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 fineness.
Clean the grinding mecha­nism as described (in para.
9.2) and remove the foreign object. Observe the safety instructions!
6. Now switch off the grinder and remove the filled bag from the spout.

Give the grinder a cooling­off break of at least 100 minutes (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.
Defect
Grinder rotates but without grinding.
Cause
Carrier breakage.
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.

8. Recalibration of the Grind Adjustment
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. 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!
Adjusting spindle
4. If you grind some beans now, you should get fine grains. If the coffee beans have been ground too fine, the discs can stick together. The grinder would be blocked.
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 „fine“. Clockwise ro­tation must no longer be possible.
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!
7. Insert the fastening screw of the rotary knob and tighten it firmly 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!

9.1 Cleaning with GRINDZ™ Grinder Cleaner
We recommend cleaning your shop grinder once a month with our GRINDZ™ Grinder Cleaner.
Pull out the power supply plug !
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.
9.3 Cleaning the grinding mechanism
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 special puller (art. no. 4041).
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 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.

During re-assembly, no ground material should stick to the surfaces where the grinder casing and the grinder casing touch each other.
9. Screw down the grinder casing cover (12) tightly with the two screws (13) while changing the side several times.
10. Plug in and switch on the grinder with the setting still at coarse.
11. Slowly turn the rotary knob to fine to make sure the discs are not touching.
12. Rotate the rotary knob back to the desired grind degree. The grinder is now ready for operation 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 device!
Check the device regularly for any signs of damage on the power supply cable, plug, finger protector, etc.
Any repairs that may be required are only allowed 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 grind capacity decreases and the ground coffee is hot and of irregu­lar grind size, you should change the grinding discs.
1. Take the grinder apart as described in para. 9.3 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.
3. Close the grinder casing again as described in para. 9.3 and set the grind degree again as described in para. 8.
11. Spare Parts
Spare parts are usually ordered from your customer service centre or your local dealer. To ensure quick, correct processing of your order, the following information is absolutely required:
