4. Setup

4.1 Unpacking and Inspection

1. Carefully remove the lathe from its packaging. It is recommended to have two people for unboxing and placement due to the machine's weight (approximately 134.2 lbs).
2. Inspect the machine for any signs of shipping damage. Report any damage to the carrier and seller immediately.
3. Remove any protective coatings or excess grease/oil from the machine surfaces using a suitable cleaner.
4. Verify all included accessories are present according to the packing list.

4.2 Placement and Mounting

• Place the lathe on a sturdy, level workbench or stand capable of supporting its weight and resisting vibration during operation.
• Securely bolt the lathe to the workbench using appropriate fasteners to prevent movement.
• Ensure adequate clearance around the machine for safe operation and material handling.

4.3 Electrical Connection

• Connect the lathe to a grounded electrical outlet that meets the machine's power requirements (750W motor).
• Do not use extension cords unless absolutely necessary, and ensure they are rated for the machine's power draw.

5. Operating Instructions

5.1 Powering On/Off and Speed Adjustment

1. Ensure all safety guards are in place and the workpiece is securely mounted.
2. Press the green 'ON' button to power on the machine.
3. Adjust the spindle speed using the speed adjustment knob. The current RPM will be displayed on the digital screen. The lathe offers a stepless adjustment from 0 to 2500 RPM.
