of the cross beater should be inspected.
Procedure:
• Pull the power plug
• Open the mill housing
• Check the gap between the grinding insert ME and the
impact plate PP with a feeler gauge = desired value
1 mm, whereby the gap to the bottom sieve may not be
< 1 mm
Attention:
The gap between grinding insert and impact plate may by no
means exceed 2 mm since this can cause damages to the in-
strument.
• Adjust the gap between the grinding insert and impact plate, if necessary.
