6) SAFETY DEVICES
A) Thermal overload protection
To eliminate the risk of fire, the motor is equipped with an overheat protection device which will cutoff the
motor’s power supply should it reach a high temperature.
In the event that the thermal protection is tripped as a result of malfunction (e.g.: jammed grindstones, worn
out bearings, foreign object in grinding chamber, etc.) the grinder main switch should be turned off
immediately and the main power plug must be disconnected. For further handling of the device contact your
local service provider, and allow the grinder to cool down before any further maintenance.
In the event that the thermal protection is tripped as a result of a long continuous operation (read section 5,
for operating intervals) allow the grinder to cool down and reset the thermal cutoff protection by unplugging
the main cable from the socket. On the first operation after resetting a tripped overheat protection device
observe the grinding quality and noise level, and if there are any irregularities shut down the grinder and call a
certified technician for a complete analysis of the grinder.
B) Grinding chamber hopper fixing screw
The grinding chamber is a hazardous area if the proper precautions aren’t observed. To avoid any hand contact
with running grindstones. Do not attempt to operate the grinder without the hopper is fully placed and fixed in its
position by hopper’s fixing screw (Fig 4.3).
