• Use appropriate fasteners to prevent any movement during operation.

4.3 Power Connection

• Connect the lathe to a suitable AC power outlet. Ensure the power supply matches the machine's requirements (1100W).
• Always use a grounded outlet.

4.4 Initial Cleaning and Lubrication

• Clean any protective grease or oil from the machine's surfaces, especially the bedways, lead screws, and chuck, using a suitable degreaser.
• Apply a thin layer of machine oil to all moving parts and unpainted surfaces to prevent rust and ensure smooth operation.

5. Operating Instructions

This section details the basic steps for operating your mini metal lathe.

5.1 Power On/Off and Speed Adjustment

• Turn the main power switch to the 'ON' position.
• Use the variable speed control knob to adjust the spindle speed. The digital display will show the current RPM (0 to 3000 rpm).
• Always start at a lower speed and gradually increase as needed for the material and operation.
