Procedure to adjust the pump pressure:
1. Place a filter with coffee of proper grind and quantity in the filter holder.
As soon as the brew lever is activated water will flow onto the coffee bed and the gauge
indicates true extraction pressure (which is practically zero at the early stage of pre-infusion).
2. Activate the group by slotting the brewing lever in its lower (pump active) position.
3. Observe the right hand pressure gauge to check how the pressure evolves.
4. To increase the pump pressure turn the screw in the pump housing clockwise. Turn the screw
counter-clockwise to decrease the pump pressure.
Beware!
The set screw is made from brass and is easily deformed. To avoid damage use a
screw driver that snugly fits the slot.
