Note: If you plan to have more than one consecutive production cycle, you can
avoid the washing between a cycle and the other, making sure you begin
with the clearer mixtures.
Before operating beater, ALWAYS check that beater's fixing knob [7] is
FIRMLY TIGHTENED and the gasket is intact and clear of any fat. Should
the knob accidentally coming lost and falling into the cylinder while
operating, this would cause serious damages to the machine.
- check that the extraction door is firmly closed and pour mixture in the cylinder. Only use suitable perfectly preserved
ingredients, in the correct amount. The maximum and minimum amounts are indicated in the Technical Handbook, in
the “Technical Data” section.
Unsuitable mixture or insufficient amount of it can cause the formation of ice, and cause damages or
irregular functioning at the cylinder and beater, while an excessive quantity of mixture can forbid the
correct refrigeration, in addition to causing an excessive stress to the motor and beater and overflows
of product.
- Close the lid of the beater;
- regulate the refrigerating time following your experience, by pressing the SETTING Pushbuttons ([K3] and [K4]) and
reading the value (in minutes) on the display. Generally 8 to 12 minutes of refrigerationare necessary, in function of the
quality and quantity of the mixture;
- press the BUZZER Pushbutton [K6] to activate the buzzer at the end of the refrigerating cycle (the relative indicator
[Z6] lightens);
- press the REFRIGERATION Pushbutton [K5];
- wait the end of the functioning, signalled by the shutting down of the REFRIGERATION indicator [Z5] and the eventual
acoustic signal.
Note: If it is necessary to add some ingredients during the refrigerating cycle, stop the beater by pressing the
BEATING Pushbutton [K2]. In these conditions the timer is in PAUSE and the residual time memorised. To
restart the refrigerating cycle, press the button once again.
At the end of the refrigerating cycle, the ice- cream is ready to be extracted:
- place an idoneous basin on the support;
- open completely the extraction door and press the EXTRACTION Pushbutton [K7]. Make easy with a suitable spatule
the settlement of the ice- cream in the basin;
- stop the beater by pressing the EXTRACTION Pushbutton [K7];
- open the lid and detach the ice- cream eventually left on the beater’s blades (by using the featured spatule letting it
settle on the bottom of the cylinder.
- press the EXTRACTION Pushbutton [K7] to extract the residual ice- cream;
- stop the beater by pressing the EXTRACTION Pushbutton [K7] and close the extraction door.
