Lubrication
The mill has numerous moving metal-to-metal
contacts that require regular and proper lubrica-
tion to ensure efficient and long-lasting operation.
Use the schedule and information in the chart
below as a daily guide for lubrication tasks.
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.
DISCONNECT MACHINE FROM POWER before
performing any lubrication task!
Important: Before adding lubricant, clean all
debris and grime from part and nearby area to
prevent contamination of new lubricant.

The headstock uses ISO 32 machine oil to lubri-
cate the gears, and is equipped with an oil-level
sight glass to gauge when the proper amount of
oil is in the headstock.
The amount of oil in the headstock must be
regularly monitored before each operation to
ensure it doesn't drop below sight glass visibility.
Headstock oil must be changed on an annual
basis to ensure proper lubricity of oil.
