PREPARATION
8. Turn the master power switch on the
electrical cabinet to the ON position.
9. Reset the STOP button by twisting it
clockwise until it pops out. The power lamp
on the control panel should illuminate.
10. To ensure the carriage components do not
unexpectedly move during the following
steps, disengage the half nut lever and feed
selection lever (see Figure 27).

11. Verify that the machine is operating
correctly by pulling the spindle lever out and
moving it down to start spindle rotation (see
Figure 28).
When operating correctly, the machine
runs smoothly with little or no vibration
or rubbing noises.
— Investigate and correct strange or
unusual noises or vibrations before
operating the machine further. Always
disconnect the machine from power when
investigating or correcting potential
problems.
12. With the spindle lever in the down
position, the spindle should be rotating
counterclockwise—down and toward you as
you face the lathe.
— If the spindle and chuck are not rotating
counterclockwise, the power supply is
connected out-of-phase. Stop the machine,
disconnect it from power, then follow the
instructions in the Correcting Phase
Polarity Wiring section on Page 88.
After correcting the wiring, repeat Steps
9–12.
13. Press the STOP button to turn the lathe
OFF, then, without resetting the STOP
button, try to restart spindle rotation. The
spindle should not start.
— If spindle rotation does start with the
STOP button pressed in, the STOP button
safety is not operating correctly. This
safety feature must operate properly
before continuing operation. Use the
spindle lever to stop the lathe, disconnect
it from power, and call Tech Support for
help.
14. Move the spindle lever to the OFF (middle)
position, reset the STOP button by twisting
it clockwise until it pops out, then restart
spindle rotation.
