When filling in lithium based grease, it must take the grease even till the grease out off from the sealing. The filling period should be shorten if there is the special working condition such as at the torrid zone, high humidity, severe dust, large temperature variation and long continuing working time. It should be filled with new grease before and after the machine being long time stop working.
2.The gear face exposed in air should periodically cleaned and spread with appropriate oil on it.
