  • Page 31: Measurement Cell

    Maintenance and cleaning 9.1.1 Measurement cell Measure Interval Clean the upper part of the measurement cell with the hand brush. When brushing, make sure that the milling disk is pointing downwards, to prevent any dirt getting into the threads. Clean the lower part of the measurement cell with the hard or soft brush, depending on the moisture and degree of gumming.

  • Page 33: Mounting The Crank Of The Hand Mill

    Maintenance and cleaning Untwist the hand mill. Remove the old knife disk by loosening the three recessed head screws. Insert the new knife disk and screw in the screws. The maximum cutting effect can be reached if the distance between the knife disk and the crank is less than 0.1 mm. This can be checked. For this purpose move the crank handle out of and into the hand mill, while the hand mill is closed.
