A) Thermal overload protection
In order to eliminate the risk of fire the motor is equipped with an overheat protection device which
willcutoffthe motor’spower supply should it reach ahightemperature.
-Intheeventthat the thermal protection is tripped asaresultofmalfunction(e.g.:jammed
blades,worn out bearings, foreign object in grinding chamber,etc.)the appliance main switch
shouldbeturnedoffimmediatelyandthemainpower plug must be disconnected. For further
handlingofthedevicecontactyourlocalserviceprovider,and allow the appliance to cool down
beforeany furthermaintenance.
-Intheeventthatthethermalprotection is tripped as a result of a long continuous operation
(readsection 5, for operating intervals) allow the appliance tocool down and reset the thermal
cutoffprotectionbyunpluggingthemaincable from the socket. On the first operation after
resettinga tripped overheat protectiondevice observe the grindingquality and noise level,and
if there are any irregularities shut down the appliance and call a certified technician for a
completeanalysisoftheappliance.
B) Grinding chamber safety screws
The grinding chamber can be a hazardous area if the proper precautions aren’t observed.
Thehoppersafetyscrew (fig4.1) and the grinding dial safety screw (fig7.2) shouldneverberemoved
during normal operation of the appliance unless the appliance is disconnected from the power
