Pulsed operation (Description from Amazon: "Safety pushbutton also for pulsed operation") they did not !!!
In the manual is to then: "Press the switch in Interwall (ie alternately press and release), so they reach a pulsed mode." Literally so depreciated including typos! The pulse must therefore come out of the forefinger.
In continuous operation, the ground material depends on the ceiling. Instead of manual pulse mode is shaken at best the whole machine during grinding, so that the ground material is toward the blade and is actually ground instead only centrifuged.
Then the mill also makes what they want!
