After the adjustment, the rotor should be rotated by hand to check whether there is clash. When the adjustment has been finished, the sleeve nut should be locked, for fear that the impact plate is affected by the vibration then the nut is loose and falls down to hit the board hammer, which may cause accidents.

The feeding must be stopped before the machine stops. The motor can be stopped just when the material inside the machine has been crushed completely.

  3. After the maintenance and the adjustment of the outlet of the toothed crusher, the rotor should be rotated by hand firstly to ensure that there is no abrasion or getting stuck between the rotor and other parts and it can rotate flexibly. Then, the motor can be started.
