Adjusting coffee dosing
•
The doser is equipped with a portion volumetric controlling knob.
•
In order to increase the dosed amount the knob should be turned counterclockwise and vice versa (Fig 5.4).
•
Test the portioned amounts by inserting a porta filter handle (not supplied) all the way into the fork shaped
support and dose one or two portions.
•
In order to achieve repeatable and consistent portioned amounts:
o
Make sure that the feeding star shaped mechanism is always overfilled with coffee powder.
o
Always retract the dosing lever all the way to the end of its stroke

Tamping
•
Place the porta filter holder against the underside of the tamping device and push it upwards.
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).
