Can any M4 owners give me a tip here. Acquainting myself with the dosing mechanism and I turned the doser dial clockwise to reduce the size of the dose - success. Tried to turn it back anticlockwise to increase the dose but no movement???
There is a gap for a screwdriver but does it need that level of force to move, given I could decrease the dosage with my fingertips?
