9. Pull up on the half nut and the feed ON/OFF
levers (see Figure 28), then use the carriage
handwheel to move the carriage back and
forth to ensure that it is not engaged with
the leadscrew or feed rod.
Note: Steps 8–9 will ensure that the carriage
and cross slide do not unexpectedly move
during the following steps.
10. To prevent the spindle from rotating when
power is applied to the motor, move the
spindle lever to the OFF (middle) position
(see Figure 28).
11. Turn the master power switch ON, then
reset the STOP button by twisting it
clockwise until it pops out. The headstock oil
pump will turn ON.
12. Observe the oil pump tube through the sight
glass on the headstock (see Figure 29).
Verify that you see oil flowing.
Important: The headstock has a pressurized oil
system that is equipped with a pressure
safety switch. If the oil is not properly
flowing, the lathe will not start.
