Model G0747/G0748 (Mfg. Since 8/12)
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.
Lubrication
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.
