HOW TO USE:

1. Set Up the Lathe: Place the lathe on a stable, level surface and connect it to a 230V or 460V power source. Secure the lathe using the provided mounting pads and levelers.
2. Install the Workpiece: Choose the appropriate chuck (3-jaw or 4-jaw) and secure your workpiece firmly in the chuck.
3. Adjust the Spindle Speed: Select the spindle speed using the speed dial, based on the material and required finish of the workpiece.
4. Setup the Cutting Tool: Insert the cutting tool into the four-way tool post and adjust its position for the desired operation.
5. Engage the Spindle: Use the control lever to start the spindle in the desired direction. Monitor the ACU-RITE 303 DRO for real-time positioning feedback.
6. Begin Machining: Move the cutting tool into position using the carriage handwheel and commence the machining process, adjusting the feed rate as necessary.
7. Monitor and Adjust: Continuously check the cutting process, making adjustments to speed and feed rates as needed for optimal results.
8. Stop the Lathe: Once machining is complete, disengage the spindle and power down the lathe using the foot brake for a controlled stop.
9. Cleanup and Maintenance: Remove the workpiece and clean the lathe, ensuring the lubrication system is topped up and all bed ways are free from debris.
