Always take care to move the lever/knob with the motor turning and empty (without coffee between the burrs). To do this you can operate the shutter (5 Fig. 2) at the base of the hopper to stop or resume the dropping of the coffee beans into the grinding mechanism."
I can't quite imagine doing this every time I want to make an adjustment, so I was wondering what you do in real life? [Not counting single-dosing, of course.]
