Depending on use, clean your GRAEF CM8007 at least once a week. Before cleaning, always remove the power plug.

• Use a soft and moist cloth to clean the outer surfaces of the unit. Use a mild detergent in case of heavy soiling.

• To clean the bean container: Remove the coffee bean container by holding the grinding ring, pressing the bean container down, and turning it counter-clockwise. Make sure that the run-through of the coffee beans is closed on the coffee bean container.

• Place any unused beans in an airtight container to keep the flavour.

• Clean the coffee bean container and the coffee grounds container in warm water using a little washing-up liquid.

• Afterwards, dry the containers well.

To clean the grinding mechanism of your GRAEF CM8007, follow these steps:

1. Remove the power plug.

2. Remove the coffee bean container as described in the general cleaning instructions.

3. Turn the grinding ring to the right as far as possible.

4. Press the “PUSH” button, and continue to turn the grinding ring to the right.

5. When the two arrows point at each other exactly, you can remove the grinding ring together with the upper grinding mechanism. Remove the upper grinding mechanism from the grinding ring.

6. Clean the lower and upper grinding mechanism with the enclosed brush.

7. After cleaning, first of all, place the grinding ring back onto the motor block (arrow pointing to arrow).

8. Now place the upper grinding mechanism back in.

9. Turn the grinding ring clockwise to the requested grinding degree.

To test if the grinding mechanism has been set correctly, turn the grinding ring to “coarse”, such as level 35, and try to pull out the grinding mechanism by the metal ring. If the grinding mechanism cannot be removed, it has been installed correctly.

10. Place the coffee bean container back on the unit.

By means of the fine adjustment of the upper grinding mechanism on your GRAEF CM8007, you can set the grinding degree to be coarser or finer. Proceed as follows:

1. Remove the upper grinding mechanism.

2. Use a screwdriver to remove the small screws.

3. Turn the grinding mechanism one stop to the right (coarser) or left (finer). IMPORTANT! Set the grinding mechanism two to three stops to the right or left maximum at first.

4. Screw the screws back in again.

5. Place the upper grinding mechanism back in again.

Here are some tips for using your GRAEF CM8007:

• Beans / types of beans react differently (oily, old, freshly ground, etcetera).

• Choose a finer grinding degree setting for Espresso.

• Choose a medium grinding degree setting for filter coffee.

• Choose a coarse grinding degree setting for French Press.

• Select a coarser grind setting if no coffee powder falls out of the ejector even though the machine is running.

• Room temperature and air humidity have an effect on the coffee beans.

• The tendency for the correct grinding degree setting for Espresso can be seen by the fact that the coffee grounds start to go lumpy. The coffee grounds are not too lumpy when dropping out; smaller to medium-sized lumps are formed which spread again when dropping out. The coffee grounds have a fine feel.

• Finding the right grinding degree is very important for preparing coffee (extraction time). In case of a wrong grinding degree, the coffee cannot be extracted in an ideal way. It is either under or over extracted.

• There is no “perfect grinding degree”. Everyone should find his or her grinding degree according to his or her taste preferences.

• The setting of the grinding degree should also take into consideration the contact pressure and the dosage as well as the roasting degree of the bean used. Some test grinds are necessary here. For this reason the contact pressure and the dosage should be kept constant; the grinding degree should be attuned.

• The finer the grinding degree, the longer the grinder needs.

• It may happen that the grinding degree has to be corrected after some time because the quality, the moisture content and the freshness of the bean depends very much on the surroundings. This can be corrected quickly by trying out and adapting the grinding degree and/or contact pressure, if the Espresso runs into the cup too quickly or too slowly.
