I (ON): In this position, the device is ready
for normal use.
8.2. Engaging the Portalter
Place the portalter directly on the appliance
on the support.
Start grinding by pressing the microswitch
button directly with the portalter.
8.3. Fork insertion and adjustment
Insert the portalter fork by turning as show
in the gure. Unlock the two knobs to adjust
the upper portalter holder.
8.4. Adjusting the Coffee Grind
To achieve your desired brew time and
coffee consistency, a manual adjustment
can be made to the grinder to modify the
grind of the coffee.
Rotate the adjustor knob as described
below.
Grinding the coffee more nely will result
in a slower extraction (pour).
This is achieved by turning the adjuster
knob towards the smaller numbers.
Conversely, turning it towards the larger
numbers will result in a coarser grind and
thus a faster extraction.
Before checking the neness of the ground
coffee, grind some doses of coffee to ll
the duct between the grinding area and
the outlet.
Note: There are many variables that can
affect the quality of coffee, including
temperature, humidity, espresso machine
settings, cleaning of the lters and
freshness of the roast. All of these can
cause slight variations in dose times.
The size of the coffee particles is
extremely important in preparing a good
cup of coffee, along with the type of
coffee blend used. The ideal grind can
be determined by making various coffees
using the amount of ground coffee that
you would normally use for each cup (we
recommend at least 6g). The best grind is
that which allows coffee to ow out from
the portalter spouts neither too slowly,
drop by drop, nor too quickly. A general
rule is that a double dose should dispense
approximately 50ml/ 2 uid oz about. of
espresso in approximately 25 seconds.
This time may be adjusted by varying the
coarseness of the grind.
8.5. Adjusting Dose Quantity
The dose quantity can be set in terms of
time (sec.).
Please refer to Software Programming
Manual for detailed instructions in the full
manual available online.
8.6. Adjusting the fork
Adjust the height of the fork used to
support the portalter using the two side
knobs.

WARNING
Be careful not to close, even
partially, the outlet chute while
brewing ground coffee.
WARNING
Be careful to position the

9. General Warnings Operation
- Do not insert foreign objects when lling
the hopper with coffee beans. Handle with
clean, dry hands.
- After any hopper lling and under normal
use of the appliance, the hopper lid must
be positioned correctly.
For the appliance to function optimally,
on its rst installation and every time the
hopper is cleaned, after having ground a
few coffee doses, clean the inner surface
of the funnel with a soft dry brush.
- In the versions with single-phase grinder,
observe the duty cycle stated on the label
located on the side of the appliance.
10. Safety devices
The appliance is equipped with a
protection device that disconnects the
motor in the event of overheating. In the
event that this protection is tripped, wait
for the motor to cool down.
Should the protection trip as a result of
anomalous operation, such as the grinding
blades jamming. If the appliance does not
start after the motor has cooled, turn off
using the on-off switch, unplug from the
mains, and contact a qualied technician.
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 performing any repair
work.
Motor locking sensor: the system that
protects against accidental contact with
the rotating parts of the grinding system
consists of two sensor, situated inside
the body of the appliance, that cut the
electricity to the motor.
If the hopper or the funnel are removed or
not properly in place, the sensor prevents
the appliance from working.
11. Noise level
