Maintenance
Before any intervention on the machine, disconnect it from the electrical supply by
pulling out the plug or switching off the main switch! Failure to comply may cause serious injury.
Lubrication
The milling machine is equipped with a “one-shot” 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. Refer to Figures 28 and 29 for lubrication requirements and access points.

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 the pulley surfaces.
