brication 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. Refer to Figures 28 and 29 for lubrication
requirements and access points.

11.2 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.
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 the pulley surfaces.
