• Connect the machine to a grounded electrical outlet. Do not use extension cords unless absolutely necessary, and ensure they are rated for the machine's power requirements.
• Before plugging in, ensure the power switch is in the "OFF" position.

4.4 Initial Cleaning and Lubrication

• Clean all protective grease and oil from the machine's surfaces, especially the bedways, lead screw, and chuck, using a suitable degreaser.
• Apply a thin coat of machine oil to all moving parts, including the bedways, lead screw, and gears, as specified in the maintenance section.

5. Operating Instructions

This section covers basic operational procedures. Always refer to the safety instructions before starting any operation.

5.1 Power On/Off and Emergency Stop

• Power On: Press the green "ON" button. The digital display will illuminate.
• Power Off: Press the red "OFF" button.
• Emergency Stop: In case of an emergency, press the large red mushroom-head button. This will immediately cut power to the motor. To reset, twist the button clockwise and then press the green "ON" button.

5.2 Spindle Speed Adjustment

• The lathe features variable speed control. Use the speed adjustment knob on the control panel to set the desired RPM.
• The digital display will show the current spindle speed. Adjust speed according to the material and operation being performed.

5.3 Workpiece Clamping (3-Jaw Chuck)

• Insert the workpiece into the 3-jaw chuck.
• Use the chuck key to tighten the jaws evenly until the workpiece is securely clamped. Remove the chuck key immediately after tightening to prevent it from being ejected during operation.
• Ensure the workpiece is centered and runs true before beginning any cutting operation.

5.4 Tool Post and Tool Bit Setup

• Select the appropriate cutting tool for the task.
• Insert the tool bit into the tool post and secure it firmly with the locking screws.
• Adjust the height of the tool bit so that its cutting edge is exactly on the centerline of the workpiece. Use shims if necessary.
• The 4-way tool post allows for quick changes and angular adjustments.

5.5 Tailstock Operation

• The tailstock can be moved along the bed and locked in position using its clamping lever.
• The tailstock quill can be extended or retracted using the handwheel and locked with the quill lock.
• Use a live center in the tailstock to support long workpieces during turning operations.
• Drill bits can be mounted in the tailstock for drilling operations.

5.6 Feed and Threading Operations

• The lead screw enables automatic feeding of the carriage for smooth cuts and precise thread cutting.
• Refer to the gear chart (if provided with the machine) for setting up the correct gears for specific thread pitches.
• Engage the half-nut lever for threading operations.

6. Maintenance

Regular maintenance is crucial for the longevity and performance of your lathe. Always disconnect power before performing maintenance.

• Daily Cleaning: After each use, clean chips and debris from the machine, especially from the bedways, lead screw, and chuck. Use a brush or air gun (with caution and eye protection).
• Lubrication: Regularly lubricate all moving parts, including the bedways, lead screw, cross slide, compound rest, and tailstock quill. Use high-quality machine oil. Check the gear train for proper lubrication.
• Gear Inspection: Periodically inspect the gears for wear or damage. Replace worn gears to maintain precision.
• Chuck Maintenance: Clean and lightly lubricate the chuck jaws and scroll plate to ensure smooth operation and proper gripping.
• Belt Tension: Check the drive belt tension periodically. Adjust if too loose or too tight.
• Electrical Inspection: Periodically check the power cord and connections for any signs of damage.
