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.
11.1 LUBRICATION
The milling machine is equipped with a "auto lube" lu-
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.
