My additional experience, but by no means lead to a devaluation of points:
1. You get the oranges something pappige or wet hands: it will happen before that a half an orange while expressing "cuts off" and ends up in the container. So - machine - grab Orange - machine - and more ...
2. Therefore, it is advisable, possibly only at level 2 to press (faster rotation = faster Orange weggeflutscht);
3. If all the fruit are squeezed, then I increase again briefly at level 4 and reach in that are brought out from the pulp by the "centrifugal" and the remains of juice.
A guide was (at least for me) not in, but it's actually not necessary. The accessory can be explained in fact by itself. I use the press for the family z. Ex. The breakfast orange juice. The cost of time an Orange alone has me a bit too high, since I take my old small hand press.
