Why it’s important to choose the good size of the nozzle?

It is very important to choose the size of the nozzle to avoid damaging your machine. In fact, choosing a smaller nozzle, the motor and pump can exceed their maximum efficiency and eventually damage the machine. Conversely, when you take a nozzle larger than that calculated, the machine did not give us the expected yield.
