The milling machine is equipped with an automatic lubrication system. The system lubricates the lead screws and ways.
An oil cup and grease nipple on the mill head provide lubrication for the spindle bearings and back gear mechanism.

Periodic maintenance requirements
During operation, periodically vacuum and brush chips
and debris from machine.
Periodically operate knee and table lead screws through
full range of movement to evenly distribute lubricant
(particularly when applied using the “one-shot” system).
Periodically apply light machine oil to work table and
other exposed metal surfaces to prevent rust or
corrosion.
Periodically remove vent panels to check pulleys and
belts for unusual wear or grooving.
NOTE: Operators
should vary speed occasionally to prevent formation of
grooves on pulley surfaces.
