Follow these steps to test a specific blend of coffee:

1. Close the gate of the container and grind all of the remaining coffee between the grinding blades (stop the grinder as soon as the grinding noise turns into a high-pitched whine).
2. Switch off the motor and empty the container.
3. Pour the coffee beans you want to test into the empty container and grind a small amount. This should be collected at the outlet (inside the dispenser-doser) using a measuring spoon.
4. Keep the grinder running until the spoon is full.
5. Remove the measuring spoon and level the grind within using the side of your finger, or weigh it to be sure you are using 6.5 to 7 grams (0.2 oz) of coffee.
6. Pour the ground coffee in the filter basket and proceed to espresso preparation.

If the grind is not suitable, adjust the settings to increase or decrease the grinding thickness.

If a new grinder is being used to test the coffee, first tighten the setting until the blades touch (do not start the motor in this position!), then turn back four or five notches. This sets a basic grind which you can subsequently adjust to obtain a finer or coarser grind as required.

Once the grind has been selected, adjust the dosage regulator for 0.2 oz (6.5-7 grams) of coffee.

CLEANING AND MAINTENANCE

The grinder should always be maintained and operated under perfect working conditions in order to obtain the best results - that is, really excellent coffee. For instance, if coffee residues are allowed to build up, they can oxidize and mix with the fresh grind to give the coffee an unpleasant, rancid odor.

Weekly Cleaning:

The container should be washed with soapy water, then carefully rinsed and dried. Household alcohol is recommended for cleaning the dispenser (unless it is made of plastic), as it is very effective in removing oily substances.

Monthly Cleaning:

The grinding blades should be checked for wear once a month, and replaced if necessary.
