The key for 4-jaw chunk the center rack and the follow tool carrier are selected parts
The lathe bed is made of high-grade iron. By combining high cheeks with strong cross ribs, a bed of low vibration and rigidity is produced. It integrates the headstock and drive unit, for attaching the carriage and leadscrew. The two precision-ground V - sideways, re-enforced by heat hardening and grinding, are the accurate guide for the carriage and tailstock. The main motor is mounted to the rear of the left side of the bed.

The headstock is cast from high grade, low vibration cast iron. It is bolted to the bed with four screws. The headstock houses the main spindle with two precision taper roller bearings and the drive unit. The main spindle transmits the torque during the turning process. It also holds the workpieces and clamping devices. (e.g. 3-jaw chuck).

The carriage is made from high quality cast iron. The slide parts are smoothly ground. They fit the V on the bed without play. The lower sliding parts can be easily and simply adjusted. The cross slide is mounted on the carriage and moves on a dove tailed slide. Play in the cross slide may be adjusted with the gibs.
Move the cross slide with its conveniently positioned handwheel. There is a graduated collar on the handwheel.
A four way tool post is fitted on the top slide and allows four tools to be clamped. Loosen the center clamp handle to rotate any of the four tools into position.

The apron is mounted on the bed. It houses the half nut with an engaging lever for activating the automatic feed. The half nut gibs can be adjusted from the outside.
A rack, mounted on the bed, and a pinion operated by handwheel on the carriage allow for quick travel of the apron.

The leadscrew (A, Fig.7) is mounted on the front of the machine bed. It is connected to the gear box at the left for automatic feed and is supported by bearing on both ends. The hex nut (B, Fig.7) on the right end is designed to take up play on the leadscrew.

The tailstock slides on a V way and can be clamped at any location. The tailstock has a heavy-duty spindle with a Morse taper No. 2 socket and a graduated scale. The spindle can be clamped at any location with a clamping lever. The spindle is moved with a handwheel at the end of the tailstock.
NOTE: Fit the securing screw (C, Fig. 8) at the end of the lathe in order to prevent the tailstock from falling off the lathe bed.

The machine is switched on and off with ON/OFF button. Depress to stop all machine functions. To restart, lift the cover and press ON button.

After the machine is switched on, turn the switch to "F" position for counter-clockwise spindle rotation (forward). Turn the switch to "R" position for clockwise spindle rotation (reverse). "0" position is OFF and the spindle remains idle.
Turn the switch clockwise to increase the spindle speed. Turn the switch counter-clockwise to decrease the spindle speed. The possible speed range is dependent from the position of the drive belt.
Turn hex socket cap screw (A, Fig.10) clockwise and tighten to lock. Turn counter-clockwise and loosen to unlock. Caution: carriage lock screw must be unlocked before engaging automatic feeds or damage to lathe may occur.

Rotate hand wheel clockwise to move the apron assembly toward the tailstock (right). Rotate the hand wheel counter-clockwise to move the apron assembly toward the headstock (left).

Clockwise rotation moves the cross slide toward the rear of the machine.
Move the lever down to engage. Move the lever up to disengage.
Rotate clockwise or counter-clockwise to move or position.
Rotate counter-clockwise to loosen and clockwise to tighten. Rotate the tool post when the lever is unlocked.
Turn hex nut clockwise to lock and counter-clockwise to unlock.

Rotate the lever clockwise to lock the spindle and counter-clockwise to unlock.
Rotate clockwise to advance the quill. Rotate counterclockwise to retract the quill
Three sets screws located on the tailstock base are used to off-set the tailstock for cutting tapers. Loosen lock screw on tailstock end. Loosen one side set screw while tightening the other until the amount of off-set is indicated on scale. Tighten lock screw.
The head spindle holding fixture is cylindrical. Loose three set screws and nuts (A, Fig.13 only two are shown) on the lathe chuck flange to remove the chuck. Position the new chuck and fix it using the same set screws and nuts.

Clamp the turning tool into the toolholder.
The tool must be clamped firmly. When turning, the tool has a tendency to bend under the cutting force generated during the chip formation. For best results, tool overhang should be kept to a minimum of 3/8" or less.
The cutting angle is correct when the cutting edge is in line with the center axis of the work piece. The correct height of the tool can be achieved by comparing the tool point with the point of the center mounted in the tailstock. If necessary, use steel spacer shims under the tool to get the required height. (Fig. 14)




Apron travel, cross travel, and top slide handwheel can be operated for longitudinal or cross feeding (Fig.17).

Longitudinal Turning with Auto-Feed
Use the table (A, Fig.18) on the lathe for selecting the feed speed or the thread pitch. Adjust the change gear if the required feed or thread pitch cannot be obtained with the installed gear set.

In the straight turning operation, the tool feeds parallel to the axis of rotation of the workpiece. The feed can be either manual by turning the handwheel on the lathe saddle or the top slide, or by activating the automatic feed. The crossfeed for the depth of cut is achieved using the cross slide.

In the facing operation, the tool feeds perpendicular to the axis of rotation of the workpiece. The feed is made manually with the cross slide handwheel. The crossfeed for cut depth is made with the top slide or lathe saddle.

For turning between centers, it is necessary to remove the chuck from the spindle. Fit the M.T.3 center into the spindle nose and the M.T.2 center into the tailstock. Mount the workpiece fitted with the driver dog between the centers. The driver is driven by a catch or face plate.
Note: Always use a small amount of grease on the tailstock center to prevent center tip form overheating.

Work to a side angle of 5 can be turned by off-setting the tailstock. The angle depends on the length of the workpiece.
To off-set the tailstock, loosen locking screw (A, Fig24). Unscreen the set screw (B, Fig.24) on right end of the tailstock. Loosen the front adjusting screw(C, Fig.24) and take up the same amount by tightening the rear adjusting screw (D, Fig.24) until the desired taper has been reached. The desired cross-adjustment can be read off the scale. (E, Fig.24). First retighten the set screw (B, Fig.24) and then the two (front and rear) adjusting screw to lock the tailstock in position. Retighten the locking screw (A, Fig.24) of the tailstock. The workpiece must be held between to centers and driven by a face plate and driver dog.
After taper turning, the tailstock should be returned to its original position according to the zero position on the scale of tailstock. (E, Fig.24)

Set the machine up to the desired thread pitch (according to the threading chart, Fig.20). Start the machine and engage the half nut. When the tool reaches the part, it will cut the initial threading pass. When the tool reaches the end of the cut, stop the machine by turning the motor off and at the same time back the tool out of the part so that it clears the thread. Do not disengage the half nut lever. Reverse the motor direction to allow the cutting tool to traverse back to the starting point. Repeat these steps until you have obtained the desired results.
Example: Male Thread

Using this universal chuck, round, triangular, square, hexagonal octagonal, and twelve-cornered stock may be clamped. (Fig.26)

Note: new lathes have very tight fitting jaws. This is necessary to ensure accurate clamping and long service life. With repeated opening and closing, the jaw adjust automatically and their operation becomes progressively smoother.
Note:
For the original 3-jaw chuck that mounted on the lathe, the factory has mounted the chuck in the best way to guarantee the holding accuracy with two "0" mark (A, Fig.26) showed on the chuck and chuck flange.
There are two types of jaws: Internal and external jaws. Please note that the number of jaws fit with the number inside the chuck's groove. Do not mix them together. When you are going to mount them, please mount them in ascending order 1-2-3, when you are going to take them out, be sure to take them out in descending order 3-2-1, one by one. After you finished this procedure, rotate the jaws to the smallest diameter and check that the three jaws are well fitted.
This special chuck has four independently adjustable chuck jaws. These permit the holding of asymmetrical pieces and enable the accurate set-up of cylindrical pieces. (Fig.27)

Use the drill chuck to hold centering drills and twist drills in the tailstock. (B, Fig.28)

An arbor is necessary for mounting the drill chuck in the tailstock. It has a No. 2 Morse taper. (C, Fig.28)
The live center is mounted in ball bearings. Its use is highly recommended for turning at speeds in excess of 600 RPM. (Fig.29)

After a period time, wear in some of the moving components may need to be adjust
The main spindle bearings are adjusted at the factory. If end play becomes evident after considerable use, the bearings may be adjusted.
Fasten the slotted nut (A, Fig.32) on the back of the spindle,loosen the outer slotted nut (B, Fig.32). Adjust the slotted nut (A, Fig.32) until all end play is taken up. The spindle should still revolve freely. Fasten the slotted nut (A, Fig.32) again and tighten the outer slotted nut (B, Fig.32).
Caution: excessive tightening or preloading will damage the bearings.

The cross slide is fitted with a gib strip (C, Fig.33) and can be adjusted with screws (D, Fig.33) fitted with lock nuts, (E, Fig.33) Loosen the lock nuts and tighten the set screws until slide moves freely without play. Tighten lock nuts to retain adjustment.

The top slide is fitted with a gib strip (F, Fig.34) and can be adjusted with screws (G, Fig.34) fitted with lock nuts. (H, Fig.34) Loosen the lock nuts and tighten the set screws until slide moves freely without play. Tighten lock nuts to retain adjustment.

The half nuts engagement can be adjusted with screws (I, Fig.35) fitted with lock nuts (J, Fig.35). Loosen the nuts on the right side of the apron and adjust the control screws until both half nuts move freely without play. Tighten the nut.

CAUTION: Lathe must be serviced at all lubrication points and all reservoirs filled to operating level before the lathe is placed into service! Failure to comply may cause serious damage!
NOTES: Lubricate all slideways lightly before every use. Lubricate the change gears and the leadscrew slightly with a lithium-based grease.
Lubricate Four oil ports (A, Fig. 36) with 20W machine oil once daily.

Lubricate two oil ports (B, Fig. 36) with 20W machine oil once daily.
Lubricate the left oil port (C Fig. 37) and right oil port (D, Fig.38) with 20W machine oil once daily.


Keep the maintenance of the machine tool during the operation to guarantee the accuracy and service life of the machine tool.
1. In order to retain the machine's precision and functionality, it is essential to treat it with care, keep it clean and grease and lubricate it regularly. Only through good care, you can be sure that the working quality of the machine will remain constant.
NOTES: Disconnect the machine plug from the mains supply whenever you carry out cleaning, maintenance or repair work!
Oil, grease and cleaning agents are pollutants and must not be disposed of through the drains or in normal refuse. Dispose of those agents in accordance with current legal requirements on the environment. Cleaning rags impregnated with oil, grease and cleaning agents are easily inflammable. Collect cleaning rags or cleaning wool in a suitable closed vessel and dispose of them in an environmentally sound way - do not put them with normal refuse!
2. Lubrication all slideways lightly before every use. The change gears and the leadcrew must also be lightly lubricated with lithium base grease.
3. During the operation, the chips which falls onto the sliding surface should be cleaned timely, and the inspection should be often made to prevent chips falling into the position between the machine tool saddle and lathe bed guide way. Asphalt felt should be cleaned at certain time.
NOTES: Do not remove the chips with your bare hands. There is a risk of cuts due to sharp-edged chips. Never use flammable solvents or cleaning agents or agents that generate noxious fumes! Protect electrical components such as motors, switches, switch boxes, etc., against humidity when cleaning.
4. After the operation every day, eliminate all the chips and clean different part of the machine tool and apply machine tool oil to prevent rusting.
5. In order to maintain the machining accuracy, take care of the center, the surface of the machine tool for the chuck and the guide way and avoid mechanical damage and the wear due to improper guide.
6. If the damage is found, the maintenance should be done immediately.
NOTES: Repair work may only be carried out by qualified personnel with the corresponding mechanical and electrical knowledge.
