Lubrication
Headstock
The headstock has a pressurized lubrication
system that consists of an oil pump, a low oil
pressure kill switch, a supply tank, oil hoses,
and a manifold with oil distribution lines. The
headstock has a series of oil lines that direct oil
to key locations, such as the spindle bearings
and upper headstock gearing, to ensure that
they always remain well lubricated, (especially
when low-speed high-load lathe operations could
potentially starve the upper headstock of oil).
The oil pump automatically turns ON and
begins oiling the headstock components when
the master power switch is turned ON and the
stop button is reset. The oil is pumped before the
spindle is started to protect the spindle bearings
against potential damage from dry starts.
Review the lubrication system diagram shown
in Figure 114 to familiarize yourself with the
function and relationship of the components.
Oil Pressure Safety Switch
To prevent costly damage to the headstock
gears and bearings, an oil pressure kill switch
shown in Figure 115 is installed on the output
side of the pump and will shut the lathe down
if oil pressure is lost for any reason. Verify that
the pump works by looking into the sight glass
shown in Figure 116, and observing the oil flow.

Never bypass this switch to force the lathe
to run. If you do, headstock gear and bearing
damage will occur if headstock components
operate without lubrication.
