Lubrication Overview

Your mill has numerous moving metal-to-metal
contacts that require proper lubrication to help
ensure efficient and long-lasting mill operation.
Refer to Figure 55 for a recommended lubrica-
tion schedule, and follow the detailed instructions
below for your mill.
Note: This recommended lubrication schedule
is based on light to medium mill usage. Keeping
in mind that lubrication helps to protect the value
and operation of your mill, you may need to per-
form lubrication tasks more frequently depending
on usage.
