Unpacking and Cleaning

1. Carefully unpack the mini lathe and check all items against the packing list. Do not discard packing material until assembly is complete. Contact customer service if parts are missing or broken.
2. Remove the wooden crate from around the lathe.
3. Unbolt the lathe from the shipping crate bottom.
4. Choose a suitable location: dry, well-lit, with ample space for servicing.
5. Using adequate lifting equipment, lift the lathe off the shipping crate bottom. Do not lift by the spindle. Ensure the lathe is balanced before moving it to a sturdy bench or stand.
6. Bolt the lathe to the stand or bench to ensure it is absolutely flat and level, preventing bed twisting.
7. Clean all rust-protected surfaces with a mild commercial solvent, kerosene, or diesel fuel. Avoid paint thinner, gasoline, or lacquer thinner as they can damage painted surfaces. Apply a light film of 20W machine oil to cleaned surfaces.
8. Remove the end gear cover. Clean all components of the end gear assembly and coat all gears with heavy, non-slinging grease.

Lathe Adjustments

IMPORTANT: Ensure the power switch is OFF and speed is turned down to zero before making any adjustments.

• Chuck Replacement: Turn off and unplug the lathe. Move the tailstock away from the chuck. Place protective material under the chuck. Remove the three bolts holding the chuck. Tap gently with a soft mallet if needed. Install the new chuck by reversing the steps.
• Jaw Replacement: Insert the chuck key and rotate counter-clockwise to open jaws fully. Manually pull out the jaws. Place jaw #1 into the desired slot, ensuring the top groove is not visible. Rotate the chuck clockwise to secure the jaw. Repeat for jaws #2 and #3.
• Tailstock Adjustment: Loosen the nut on the tailstock base, reposition, and retighten. Offset the tailstock for cutting bevels or tapers.
• Tailstock Locking: Turn the clamping lever clockwise to lock, counter-clockwise to unlock.
• Tool Post Adjustment: Loosen the two bolts holding the tool post, move to the desired position, and retighten. Loosen bolts on top of the tool post to replace cutters.
• Carriage Adjustment: Rotate the carriage handwheel clockwise to move towards the tailstock (right); counter-clockwise to move towards the chuck (left).
• Carriage Locking: Turn the toolpost control handle clockwise to tighten, counter-clockwise to loosen. Unlock before using automatic feeds.
• Cross Slide Adjustment: Turn the cross slide handwheel to move the tool post perpendicular to the ways. Clockwise moves it back, counter-clockwise moves it forward.
• Carriage Feed Control: Move the half nut lever down to engage automatic carriage feed. Disengage before making adjustments to prevent unexpected movement.
• Compound Control: Turn the compound control wheel counter-clockwise to move the compound outwards; clockwise to move it inwards.
• Quill Locking: Rotate the lever clockwise to lock the spindle; counter-clockwise to unlock.
• Tail Feed Adjustment: Rotate the tail feed handwheel clockwise to advance the tailstock towards the chuck; counter-clockwise to retract it.
• Tailstock Quill Clamping Lever: Rotate clockwise to lock the spindle; counter-clockwise to unlock.
• Tailstock Quill Traverse Handwheel: Rotate clockwise to advance the quill; counter-clockwise to retract the quill.
• Tailstock Offset Adjustment: Use the three set screws on the tailstock base to offset for cutting tapers. Loosen the lock screw, then loosen one set screw while tightening another to achieve the desired offset, indicated on the scale. Tighten the lock screw.

Operation

1. Emergency Stop Button: Press to stop all machine functions. To restart, lift the cover and press the ON button.
2. ON/OFF Switch: Used to switch the machine on and off.
3. Change-over Switch: Turn to 'F' for counter-clockwise spindle rotation (forward), 'R' for clockwise rotation (reverse). 'O' is OFF.
4. Variable Speed Control Switch: Turn clockwise to increase spindle speed; counter-clockwise to decrease. Speed range depends on belt position.
5. Carriage Lock: Turn the hex socket cap screw clockwise to lock, counter-clockwise to unlock. Caution: The carriage lock must be unlocked before engaging automatic feeds to prevent damage.
6. Longitudinal Traverse Handwheel: Rotate clockwise to move the apron assembly towards the tailstock (right); counter-clockwise towards the headstock (left).
7. Cross Traverse Lever: Clockwise rotation moves the cross slide towards the rear; counter-clockwise towards the front.
8. Half Nut Engage Lever: Move down to engage; move up to disengage.
9. Compound Rest Traverse Lever: Rotate clockwise or counter-clockwise to move or position the compound rest.
10. Tool Post Clamping Lever: Rotate counter-clockwise to loosen and clockwise to tighten. Rotate the tool post when unlocked.

Tool Set Up

• Clamp the turning tool firmly in the tool holder. Minimize tool overhang to 3/8" or less for best results.
• Ensure the cutting edge is in line with the workpiece's center axis.
• Achieve the correct tool height by comparing the tool point with the tailstock center. Use steel spacer shims if necessary.

Image Description: Figure 14 illustrates the correct tool height adjustment using shims.

Machining Operations

• Longitudinal Turning with Auto Feed: Use the provided table for selecting feed speed or thread pitch. Adjust change gears if the required feed or pitch is not obtainable with the installed set.
• Workpiece Holding and Drilling: Use the chuck to hold the workpiece firmly. Use the tailstock to press a drill into the rotating workpiece.
• Face Cutting: Hold the workpiece with the chuck. Use the tool post to press a cutter into the face of the workpiece. The cutter edge should be level with the center.
• Internal Cutting: Hold the workpiece with the chuck. Rotate the tool post to position the cutter in the middle of the workpiece's front face.
• Bevel Cutting: Hold the workpiece with the chuck. Adjust the angle of the tool post to cut bevels.
• Thread Cutting: Hold the workpiece with the chuck and engage the half nut. Use the tool post to press a cutter into the face of the workpiece. Refer to the thread cutting table for adjustments.

Image Description: Diagrams illustrate thread cutting and related adjustments. The table provides settings for various thread pitches and feed rates.

Maintenance

Regular maintenance is essential for the accuracy and service life of the machine tool.

• Keep the machine clean, greased, and lubricated regularly.
• Note: Disconnect the machine from the mains supply before performing any cleaning, maintenance, or repair work.
• Dispose of oil, grease, and cleaning agents according to legal environmental requirements. Store flammable cleaning rags in a suitable closed container.
• Lubricate all slide ways lightly before each use. Lubricate change gears and the lead screw with grease.
• Clean chips from sliding surfaces promptly and check regularly to prevent chips from entering between the saddle and the lathe bed guideway. Clean asphalt felt periodically.
• Notes: Do not remove chips with bare hands due to sharp edges. Avoid flammable solvents or agents that generate noxious fumes. Protect electrical components from humidity during cleaning.
• After each day's operation, remove all chips, clean machine parts, and apply machine tool oil to prevent rusting.
• Take care of the center, chuck, and guideway surfaces to maintain machining accuracy and avoid mechanical damage or wear.
• If damage is found, perform maintenance immediately.
• Notes: Repair work may only be carried out by qualified personnel with the necessary mechanical and electrical knowledge.
