1. Maintenance of bearing. Bearing is the important and essential part in sand making machine, but it is easy to wear. Bearing should be cleaned every 2000 working hours. Usually, the main shaft bearing should be replaced after 7200 working hours with new one. In addition, the lubrication should be done and always keep clean. If the oil is not clean, it will increase the wear between bearings or other parts.
