Safety Foot Brake

This lathe is equipped with a foot brake (see Figure 9) to quickly stop the spindle instead of allowing the spindle to coast to a stop on its own. Pushing the foot brake while the spindle is ON cuts power to the motor and stops the spindle. After the foot brake is used, the spindle lever must be returned to the OFF (middle) position to reset the spindle switches before re-starting spindle rotation.

Figure 7. Control panel.

Z.Coolant Pump Switch: Controls coolant pump motor.

AA.EMERGENCY STOP Button: Stops all machine functions. Twist clockwise to reset.

AB. Power Lamp: Illuminates when main power switch is turned ON and EMERGENCY STOP button is reset.

AC. Jog/Inching Button: Powers forward spindle rotation as long as it is pressed.
