 - Selectadrinkwiththeadditionoffreshmilk.Asthedrinkismade,observethemilkowfromthe
cappuccinatoreadapter.Theowshouldbeuniform,withoutany"pulsations"or"jerks"(thefoamshould
bepouredintoacupintheformofasmoothstreamwithoutanysplashesorinatingbubbles).
- Observe the cappuccinatore adapter - it's manufactured of transparent plastic to facilitate its con-
tamination level inspection and adjustment process.
Fig.4.9
 - Atthecappuccinatoreandtheadapterjointthere'sagap(seeg.4.9).Thefoamshouldn'trunout
of the adapter during the operation.
- If there's no foam coming out, but a slightly foamed milk, turn the foam control knob counter-clock-
wise. By doing this you are slightly opening the air delivery tap, and the milk foam should start coming out.
- If the foam is squirting out from the above-mentioned gap, this means that there's too much air
supplied. Turn the control knob clockwise.
The optimal foam adjustment:
The foam is streamed out uniformly and without any pulsations. The foam doesn’t overow out-
side the cappuccinatore adapter and should have a ne-porous structure.
When lowering a stirrer to a cup it stands in the foam without declining (the height of the foam
should be higher than the middle of the stirrer).
If having trouble adjusting the foam in accordance with the above instruction, proceed to the following
section:“Offsettingtherangeofadjustmentsontheairnetuningvalve”(seebelow).
