5.Press tab in on side of Emergency Stop button, lift switch cover, and press green ON button to reset Emergency Stop button. The spindle speed display and power button should illuminate to indicate that lathe is con- nected to power supply.

6.Verify lathe is operating correctly by turning spindle direction switch to "F" position. Slowly turn variale speed dial clockwise until spindle speed display shows 100 RPM. The spindle should rotate counterclockwise—down and toward the front of the lathe.

7.Push Emergency Stop button to turn lathe OFF. Then, without resetting Emergency Stop button, try to restart spindle rotation by turning variable speed dial all the way coun- terclockwise to "0" and then clockwise. The spindle should not start.

—If spindle does start with Emergency Stop button pressed in, the button is not oper- ating correctly. This safety feature must operate properly before continuing opera- tion. Turn variable speed dial counterclock- wise to "0" to stop lathe, disconnect it from power, and call Tech Support for help.

Congratulations! The test run is complete. Turn lathe OFF and perform the following Spindle Break-Inprocedure.
