Operating intervals:
•The manufacturer is not recommending using the grinder continuously for a period of time exceeding 12
minutes (or continuously grinding over 1KG of coffee).
•It is a normal occurrence that during long grinding periods the grinding chamber will heat up. In order to
achieve best grinding results, it is recommended to grind coffee in short intervals of not more than few
minutes each.
Adjusting coffee grind (Fig 5.2)
•The Aroma II grinder is equipped with step-less grinding adjustment coupled with a revolutionary encoder
micrometric measurement of the grind setting and LCD display
•The grinding blades’ distance was factory pre adjusted to satisfy different common coffee grinds from super
fine to extra-coarse. The entire range can be achieved by turning the dial over 13 complete turns.
•Turning the grinding dial counterclockwise will make the grind finer and turning it clockwise will make the
grind coarser. Along with the dial turning the LCD will show different setting reading. On the table below you
can find the different setting corresponding to different coffee grinding:
LCD reading
Coffee Grind usage
Dial turns
(from most fine position)
1-7
Turkish coffee grinding
Most fine to two turns
8-18
Espresso coffee grinding
Two turns to six turns
18-25
Filter and French press
Six to nine turns
Over 25
Coarse grinding usage
Nine to thirteen turns
•Grind a small amount of coffee and test its coarseness with your espresso machine.
•As coffee beans’ qualities and characteristics are changing from time to time it is recommended repeating this
adjustment once in a while.
Calibrating the encoder measurement and LCD display (Fig 5.3)
•As a rule, refrain from changing the grind setting position while the grinder is not connected to the electricity.
In the case you suspect the setting display and the actual setting are misaligned please find below a simple
step by step procedure to calibrate the display reading with the actual grinding setting:
oClose the beans hopper door, grind empty the grinding chamber (till no more noise of grinding is
coming from the grinder when it is operated)
oTurn the dial knob counter clock wise (Fine direction) till reaching the knob’s mechanical stop (where
the knob can not turn any further)
oInsert any kind of 1-2mm diameter pin through the reset hole, and gently press the internal reset
button continuously for over 3 seconds.
oRe-calibration is done! Now, the grinding setting and the display are aligned.
oReturn the grinding setting back to your previous setting (clock wise), while doing so please note that
the display will immediately change from showing ‘– – ‘ to show ‘01’ after a very minimal turn.

6) SAFETY DEVICES
A) Thermal overload protection
In order to eliminate the risk of fire the motor is equipped with an overheat protection device which will cutoff the
motor’s power supply should it reach a high temperature.
•In the event that the thermal protection is tripped as a result of malfunction (e.g.: jammed blades, worn out
bearings, foreign object in grinding chamber, etc.) the appliance main switch should be turned off immediately
and the main power plug must be disconnected. For further handling of the device contact your local service
provider, and allow the appliance to cool down before any further maintenance.
•In the event that the thermal protection is tripped as a result of a long continuous operation (read section 5,
for operating intervals) allow the appliance to cool down and reset the thermal cutoff protection by
unplugging the main cable from the socket. On the first operation after resetting a tripped overheat
protection device observe the grinding quality and noise level, and if there are any irregularities shut down the
appliance and call a certified technician for a complete analysis of the appliance.
B) Grinding chamber safety screws
The grinding chamber can be a hazardous area if the proper precautions aren’t observed. The hopper safety screw
(fig4.1b) should never be removed during normal operation of the appliance unless the appliance is disconnected
from the power source.
C) Coffee outlet guard
The coffee outlet guard (Fig 6.1) must always be fixed to the doser. On normal operation never remove the coffee
outlet guard (unless when cleaning the doser, please refer to Chapter 9 Cleaning).
