Page 28: Using The Device
Using the device Using the device CAUTION! Before starting the machine, make sure that the grinding bowl has been clamped correctly and that there are no loose parts inside the device. There is a risk of loose grinding bowls or parts being projected. Failure to observe this will render void the guarantee, and releases us from liability for any resulting damage to the device as well as for any resulting personal injury. - Page 29 Using the device CAUTION! The grinding element is subject to normal wear during use. Before every grinding operation, check the wall thickness of the grinding bowls. In the event of severe wear, replace the grinding bowl. If this is not done, the prevailing high centrifugal forces during grinding may cause the grinding balls to penetrate the bowl's wall and damage the mill.
