ADJUSTMENT

GRINDER SET UP

Place the hopper (2) on the grind regulator (7) and make sure the bean trap (4) is in the closed position (Fig. 1).
Lock the hopper (2) in place using a phillips head screw driver to gently tighten the hopper security screw making it match to the hole at the bean hopper collar (3) (Fig. 2).
Remove the hopper lid (1), fill the hopper with coffee (2), and replace the lid on the hopper (1) (Fig. 3).
Plug in the grinder, and press the main power switch (7) to ON position, and open the bean trap (4) to allow coffee to pass into the grind chamber (Fig. 4).

GRIND ADJUSTMENT SYSTEM
Rotate the grind regulator (7) until reaching the grind level desired.

Rotating the grind regulator clockwise will result in a courser grind; turning the regulator counterclockwise will result in a finer grinder (Fig. 1).
Only for a K6 model: Once you reach the desired grinding point, you can fix the grinding regulation using the regulation brake (5) (Fig. 2).

NOTE: It is recommended that this operation be performed, when changing to a finer grinding, with the motor running, to prevent coffee from building up between the burrs and blocking the grinder.
NOTE: If the coffee throughput is very low, this is because the coffee is being ground very fine. If the throughput is very high, this is because the coffee is being ground very coarse. A perfect Espresso is produced when the grinding gives an infusion of 25 ml of coffee in 25 seconds using about 7 g of ground coffee.

REGULATION OF THE DOSE OF COFFEE SERVED
The dispenser is factory calibrated to serve about 7 grams of ground coffee, but this amount can be adjusted between 6 and 10 grams in the following way:

Remove the dosing lid (14) and turn the adjustment bolt (12); in a clockwise direction we will obtain a smaller dose of coffee, and in an anti-clockwise direction to obtain a larger dose (Fig. 3).
Once the dose has been adjusted, refit the cover of the ground coffee dispenser with the dosing lid(14).

OPERATION

MAIN SWITCH
The main switch (13) has the following positions: OFF/ON.

UTILIZATION

Turn on the grinder using the ON – OFF switch (13), the appliance starts grinding coffee. The grinder will stop grinding coffee when the dispenser reaches the maximum possible capacity level in the dispenser and will restart after serving approximately 8 doses of coffee, to return to its maximum level.
To serve the coffee doses, place the filter holder on the support fork (11), bringing it to the bottom so that it is under the ground coffee spout. Pull the dosing lever (9) to obtain a dose of coffee (one dose corresponds to one coffee), and let the lever return to its position without accompanying it (Fig. 1).

TAMPER
Position the portafilter below the tamper (8) and push up to tamp the ground coffee (Fig. 2).

CLEANING

GENERAL CLEANING

To ensure that the grinder functions properly, and produces the highest quality grind possible, the parts that come into contact with coffee should cleaned periodically.
General Cleaning guidelines as follows:
Always turn the main power switch to the off position (13).
Unplug the machine from the power source.
Do not submerge the grinder in water or use power washing devises.
The appliance is not to be cleaned with a water jet or a steam cleaner.

BEAN HOPPER CLEANING

In order to properly clean the bean hopper (2), first empty out all remaining beans and fragments.
To remove the hopper, first close the bean trap (4), and then loosen the hopper lock screw (3) and lift the hopper straight up.
Clean the hopper (2) with a moist soft cloth or with a small amount of water and neutral soap to eliminate any oily residue from the beans.
Replace the bean hopper (2) following the same steps as the removal process, but in reverse.

CLEANING THE GROUND COFFEE DEPOSIT

To proceed with the cleaning of the ground coffee deposit, empty all the coffee that is inside.
Remove the ground coffee dispenser lid (14) and clean the entire interior with a brush.
Once everything has been clean, we finish the operation, always checking the dose of coffee served following the instructions in point 8.3.

CLEANING THE GRIND CHAMBER

It is recommended that the grind chamber be cleaned monthly with a cleaner . This process will eliminate smelly residues from the coffee remains, which can negatively affect the quality of the brewed coffee.
Care is needed when handling cutting burrs during cleaning.
The steps to follow are:
- To properly clean the bean hopper (2), first empty out all remaining beans and fragments.
- Close the bean trap on the hopper (4) and grind out the remaining coffee in the grind chamber.
- Pour the recommended grinder cleaning product into the bean hopper (2) and open the bean trap (4), allowing the cleaning product to pass into the grind chamber.
- Grind the cleaning product at a medium coarse grind setting until the
- recommended amount is passed through the system and nothing remains in the grind chamber.
- Clean the hopper (2) and refill with coffee beans.
- Discard the first 2-3 doses of coffee to assure that the residual cleaning product is removed from the grind chamber and set the grind regulator to the desired setting (5).
- Following these steps will ensure that the grinder is clean and ready for use.
- We do not recommend the taking apart of the grind assembly unless changing burrs, or removing a blockage/obstruction in the grind chamber. Removal of the grind assembly should be performed by a qualified service technician.
