»  Under normal operating conditions, bearing temperature should not exceed 30 °ś and the maximum temperature not exceed 70 °ś. If more than 70 °ś, you should immediately stop and identify the cause and to be eliminated.

»  First of all, stop feeding before parking. Only after all the material discharged you can turn off the motor.

»  When parking caused by the material congestion , they should immediately turn off the motor and the material must be cleared before the motor starts again.

»  when the end of fixed jaw plate wear and tear, you can exchange the other end.

» Crusher used for a period of time should be re-tighten all fasteners.

2, lubrication

»  To ensure the normal operation,the machine and the extension of all life should be regularly oiling lubrication.

» The grease added within the bearing capacity should be 50 to 70% and every 3 to 6 months replaced.When exchange g

rease you should open the release bearing hole to carefully clean gasoline or kerosene and other parts of roller bearings.


»  The machine adopts the

grease should be based on the location of the machine,the temperature and other conditions. We generally use calcium sodium grease and grease drier in the bath.we can also use light oil and grease blending before use.

»  When assembly or repair we can just add the right amount of grease between the bracket.
