6.5 Opening aid
An opening aid is also included with delivery of the MM 500 nano. Both sides of this tool can be
used.
The clamping screws on the grinding jar cover can be tightened or loosened using the (ÖS)
side. The locking wheels on the grinding jar support are loosened using the (ÖR) side.

It is essential to use the opening aid to close the grinding jars because tightening the
clamping screws by hand is not sufficient.
By contrast, manual tightening of the locking wheels without the opening aid is sufficient
when clamping the grinding jars in the grinding jar supports.
The opening aid can be used to unscrew the clamping screws on the grinding jar and the
locking wheels on the grinding jar support.
