6.12 Conducting a grinding operation
n After the conditions specified in Ä Chapter 6 ‘Using the device’
on page 28 have all been observed, close the hood (3).
n Press the START button on the control panel.
n The hood is locked and the mill starts up.
n The mill turns at the set speed (nominal speed). If the load is too
great, for example due to heavy grinding bowls, the speed is reduced
(actual speed) so that the machine is not overloaded.
® If the mill does not start, see Ä Chapter 9 ‘Repairs’ on page 45
While in operation, the hood (3) remains locked, even
during pause times, and the fan cools the interior.
6.12.1 Overload
If the mill is overloaded, the speed is reduced and the REDUCED SPEED
light flashes.
The mill switches off if the overload continues for too long; see
Ä Chapter 9.1 ‘Checklist for troubleshooting’ on page 45.
