INTRODUCTION AND SWITCH ON This coffee grinder delivers coffee doses in timed mode. Place the grinder on a hori- zontal surface that is perfectly stable and as vibration-free as possible. Set up the coffee grinder be- fore operating: 1 Plug the coffee grinder to the electrical main. 2 Bring the switch 7 in the switch ON position “I”. When switched ON for the first time, the coffee grinder will be set to the mode set by the factory. In the following uses, it will maintain the last mode pre- vious to switch OFF. When switched ON, the dis- play shows the Victoria Ardui- no logo for about 3 seconds.

PREPARATION TO USE 1 Open the cover 1 and fill it with coffee beans. 2 Pull the tab inside the con- tainer to allow the passage of coffee.23

GRINDING SETTING Use the knob 4, turning it clockwise for finer grinding or anti-clockwise for a coarser grinding. ATTENTION Grinding setting must be performed gradually, grind- ing a little coffee each time that the knob is turned by two digits (notches). The coffee grinder may seize up if the knob is moved by one turn while the motor is switched off. The setting has no stop points and each turn of the knob cor- responds to a movement of

0.4 mm of the burrs.

The coffee grinders equipped with resettable knob can be set to zero at a preset grinding point by holding the top part of the knob in position and us- ing the ring nut on the base.

FILTER HOLDER FORK HEIGHT ADJUSTMENT If the size of the filter holder should be larger than the set one, the fork can be adjusted. Using a crosshead screwdriver, loosen the fastening screw of the filter holder fork 5. It is recommended not to un- screw the screw completely.25

Raise or lower the fork in order to adjust it according to filter holder dimensions. Once having reached the cor- rect position, make sure that is properly levelled and tighten the fork fastening screw 5.

DOSE DISPENSING Pressing a dose button A, B or C selects the dose to be ground and the display shows the set grinding time. The dose button C, when set to 0 seconds brewing time, activates continuous grind- ing, which means that coffee is grounded continuously for as long as the filter holder re- mains inserted. To start grinding coffee, place the filter cup on the fork 5 and push it forward under the spout 6. The coffee grinder is equipped with filter holder retaining device. This device is suitable for Standard Victoria Arduino fil- ter holders, but it can be ad- justed according to the availa- ble filter holder. ATTENTION To avoid clogging the spout 6, keep the filter cup placed on the fork 5 and do not bring it close to the spout 6 during grinding.27

For timed doses, the display starts counting down when grinding begins. When grinding is complete, the display shows the initial dose time again. If the dose partialisation is not active and the filter hold- er is removed before the time expires, grinding will still con- tinue until the time ends. Instead if it is active, the grinding stops and the dis- play shows the remaining time. To resume grinding for the re- maining time, simply reinsert the filter holder. Instead, for the continuous dose, incremental counting from 0 of the grinding time be- gins on the display. When finished, the display shows the duration of the last grind. The next time the filter holder is inserted, the count restarts from 0.

BARISTA MODE If barista mode is active, for timed doses it is possible to change the grinding duration in real time by pressing the in- crease and decrease buttons. Real-time changes become ef- fective and permanent in the dose settings.29

COFFEE GRINDER To switch OFF the coffee grinder, press the switch 7 in the switch OFF position “0”. The display, the buttons and the lights will switch OFF. For long pauses and for the safety of people, it is good practice to also disconnect the plug from the mains.31
