Lubrication

The mill has numerous moving metal-to-metal contacts that require regular and proper lubrica- tion to ensure efficient and long-lasting operation, and to protect your investment.

Other than the lubrication points covered in this section, all other bearings are internally lubricated and sealed at the factory. Simply leave them alone unless they need to be replaced.

Before performing any lubrication task, DISCONneCT THe MILL FROM POWER!

Important: Before adding lubricant, clean the debris and grime from the oil cup or grease fitting and the immediate area to prevent contamination of the new lubricant.

Use the schedule and information in Figure 51 as a daily guide for lubrication tasks. Follow the referenced sections on the following pages for detailed instructions.

The following recommended lubrication schedule is based on light to medium mill usage. Keeping in mind that lubrication helps to protect the value and operation of the mill, you may need to perform the lubri- cation tasks more frequently depending on your usage.
