By adjusting the dispenser lever (Figure 4-15, Item 1), the position of the switch slide, in the dispenser container is modified. This changes the volume of the dispenser container and hence the quantity of ground coffee that it can hold before it is full. Each slider setting alters the coffee quantity by approx. 0.5 grams.
