13.0 Maintenance
Before any intervention on machine, disconnect it from electrical supply by pulling out plug
or switching off main switch! Failure to comply may cause serious injury.
13.1 Lubrication
The milling machine is equipped with a “one-shot” lubrication system. The system lubricates the lead screws and
ways. Oil cups provide lubrication for spindle bearings and back gear mechanism. Refer to Table 3 and Figures
15/16 for lubrication requirements and access points.
