Operation of the appliance

PRELIMINARIES

• Make sure the hopper is positioned correctly on the appliance and fixed to the casing with relevant pins.
• Close the locking slide and fill the hopper with coffee beans. Open the locking slide so that the beans are allowed to drop into the grinding system.
• SWITCHING THE APPLIANCE ON AND OFF

Vulcano Automatic

• In order to power up the appliance, turn the on-off switch knob to I.
• The appliance starts automatically every 12 portions of coffee (every 6 portions in the version with shorter doser group). It switches off automatically when the doser is filled with ground coffee.
• In order to switch the appliance on manually, the switch knob must be turned all the way (to START).
• In order to switch off the appliance manually, set the on-off switch knob to O.

Vulcano on Demand
In order to power up the appliance, set the on-off knob to I. The display located on the lid of the push button panel will show a counter with the incremental number of doses ground by the appli-ance. 

• After having placed the filter holder on the filter holder fork push:
  • the push button on the left (indicating one cup) to grind and dispense a single dose;
  • the push button on the right (indicating two cups) to grind and dispense a double dose.
• The counter adds one for each single dose (one cup sign) and adds two for each double dose (two cup sign).
• One can manually activate the appliance keeping pushed the push button for manual grinding (indicating ) located in the centre of push-panel. Hold down the push button for manual grinding and the grinder will grind until you lift the finger. By using the push button for manual grinding no dose is added in the counter.
• We suggest to use the push button for manual grinding to adjust the grinding of the appliance.
• In order to switch off the appliance turn the knob of the switch to O.

ADJUSTING GRINDING

• In order to achieve finer or coarser grinding, move the grinding adjustment level. To increase the coarseness of the ground coffee, the adjustment level must be rotated clockwise; to increase the fineness, turn the level anticlock-wise.
• The adjustment level remains in the chosen position without having to be locked in place. The adjustment must be performed with the motor on, and preferably without any coffee between the grinding blades. Grind small amounts of coffee in order to determine the optimal degree of fineness.
• In the Vulcano on Demand, before checking the fineness of the ground coffee, grind some doses of coffee to fill the duct between the grinding area and the outlet. This operation must be done whenever the grinding setting has been changed in order to empty the duct of the previous ground coffee. The change of the grinding setting might vary the weight of the doses. Therefore adjust the doses only after the grinding setting.

In case the range of grinding adjustment is not enough, to get the requested grinding set, please proceed as the following:

• close the locking slide and switch the grinder off;
• unscrew the check pins of the coffee bean hopper and remove it;
• remove the screws which fix the grinding adjustment level into the grinding adjustment disk and remove the level;
• fit back the level and put the holes in line with the ones of the adjustment disk so to allow a wider grinding adjustment;
• tighten the screws of the level into the adjustment disk;
• put the hopper back;
• only after having secured the hopper into the grinder cabinet by tightening the pins, open the locking slide and proceed with the grinding adjustment. HOPPER

If the coffee comes out of the espresso coffee machine very quickly, it means the coffee is ground too coarse. Vice versa, if it comes out too slowly, it means the coffee is ground too fine. Nonetheless, bear in mind that there are many conditions liable to influence the correct supply, such as the weight of the portions, the compacting, the espresso machine settings, and the cleaning of the filters.

COFFEE DOSE ADJUSTMENT

Vulcano Automatic

• In order to adjust the size of the portion dispensed, the small knob located in the centre of the ground coffee storage container must be turned while holding still the star shaped dosing unit.
• By turning the small knob clockwise, the portion is reduced. Turning it antilock-wise results in an increase.
• In order to collect the portions of ground coffee dispensed, insert the coffee machine’s filter holder all the way onto the fork-shaped support under the ground coffee outlet. In order to release a portion of ground coffee, the doser level must be pulled all the way and allowed to return on its own. Pull twice in a row for a double portion.
• To centre the coffee drop into the filter holder, it is possible to carry out a side-ways adjustment of the support fork located under the dispenser, by slightly loosening the fixing screws and then tightening them again after having moved the fork into the new position.
• If necessary, use shims (included in the package) to back the position of the fork. After finding the best position, fix the fork with the appropriate screws.

Vulcano on Demand

• In order to adjust the size of the portion dispensed, use the push button controls located on the lid of the funnel. After having set the optimal degree of fine-ness, check the weight of the dose with a digital precision scale.
• In order to adjust the dose press the push button “MENU” for 3 seconds; the display will blink.
• Select the dose you wish to adjust : either the single dose (indicating one cup) or the double dose (indicating two cups). The display will show the grinding time (in seconds) of the selected dose. By pressing the push buttons “+” and “-“ the grinding time can be increased or decreased and consequently the selected dose can be increased or decreased.
• Approximately, a change of 0.10 seconds is equivalent to a change of dose of 0.3 grams (0.01 ounces).
• To set the desired amount of grinding time press the push button “MENU” for 3 seconds. A blinking of the display will confirm the data have been saved and the exit from the adjusting program. Use a digital precision scale to check again the weight of the dose and, if necessary, repeat above mentioned operation.
• WHEN YOU ARE INSIDE THE ADJUSTING PROGRAM IT IS NOT POSSIBLE TO OPERATE THE APPLI-ANCE.
• IF THE APPLIANCE GETS SWITCHED OFF (SWITCH IN THE POSITION O) BEFORE EXITING FROM THE ADJUSTING PROGRAM THE CHANGES ARE NOT SAVED.
• In order to collect the portions of ground coffee, insert the filter holder all the way onto the fork-shaped support under the ground coffee outlet.

Warnings regarding operation

• Do not leave the appliances turned ON without coffee in the hopper.
• In the Vulcano Automatic, avoid pulling the dosing level partially, always pull it all the way.
• Do not insert, when filling the hopper with coffee beans, foreign objects. Handle with clean hands.
• After any hopper filling and in normal use of the appliance, the hopper lid must be positioned correctly.

FIRST INSTALLATION
For the correct use of the grinding blades, at the first installation or whenever the grinding blades have been replaced, grind some doses of coffee. Do not use those first doses. In the Vulcano on Demand, for the appliance to function at its best, on its first installation and every time the hopper is cleaned, after having ground a few coffee doses, clean the inner surface of the funnel with a dry brush.

OPERATING RANGE OF THE MOTOR

• IN THE VERSIONS WITH SINGLE-PHASE MOTORS, OBSERVE THE DUTY CYCLE STATED IN THE LABEL LOCATED ON THE SIDE OF THE AP-PLIANCE.
• E. g. : a data on the label 35s ON / 45s OFF points out an allowed duty cycle of 35 seconds switched on and 45 seconds switched off. APPLIANCES WITH THREE-PHASE MOTORS ARE ALLOWED FOR CON-TINUOUS WORKING.
• In order to achieve good grinding, it is nonetheless recommended to operate the appliance at intervals, allowing it to operate for no more than 10-15 minutes at a time.

Safety devices

• THERMAL OVERLOAD PROTECTION
  The appliance’s motor is protected against overheating resulting from over- currents by a thermal overload protection which, when tripped, cuts off the power supply to the motor. Should the protection trip as a result of anomalous operation, such as the grinding blades jamming, the appliance must be turned off using the on-off switch, UN-PLUGGED FROM THE MAINS, AND SKILLED TECHNICAL PERSONNEL CONTACTED. NEVER PERFORM ANY WORK ON THE APPLIANCE WHILE IT IS ATTACHED TO THE MAINS, TO AVOID THE RISK THAT MOTOR TURNS ON SUDDENLY. If the appliance overheats as a result of the motor stopping, allow the appliance to cool down before per-forming any repair work.

• MOTOR LOCKING MICROSWITCH
  The system that protects against accidental contact with the rotating parts of the grinding system consists of a microswitch, situated under the body of the appliance, that cuts the electricity to the motor.
  

The push button that controls this device is operated by a tongue in the collar of the hopper. If the hopper is removed or not properly in place, the microswitch prevents the appliance from working. To ensure the hopper is positioned correctly it must be fixed to the casing using the relevant pins.

COFFEE OUTLET GUARD
The coffee outlet guard must always be fixed to the doser (Vulcano Automatic), or to the funnel (Vulcano on Demand), using the relevant screws, which must never be removed by the user. THE REMOVAL OF THE COFFEE OUTLET GUARD CAN BE DONE BY SKILLED TECHNICAL PERSONNEL ONLY AFTER DISCONNECTING THE APPLIANCE FROM THE POWER SUPPLY BY UNPLUGGING.  Before reconnecting the appliance to the power supply, fix the safety device to the doser, or to the funnel, by relevant screws.
