jar. The clamping screws may break off, however, if too much force is exerted with the
opening aid.

empty (no grinding balls, no sample material)!
•
Switch the device off immediately if it is vibrating strongly and
making a loud noise, and check the number, the gross weight and
correct position of the grinding jars.
