INSTALLATION? CAUTION: THE MACHINE MUST BE SECURED, FIRM AND STABLE. DON T TURN DOWN OR MAKE ANY SUDDEN MOVEMENT WITHOUT INSPECTION BECAUSE OF SHAKING, WIND POWER, LASHING OR OTHER EXPECTED OUTER POWER OR INTERNAL MOVEMENT FORCE (SUCH AS FORCE, MOTOR POWER FORCE, ETC.) 5. FOUNDATION The base of the machines foundation must be solid and heavy enough to support the weight, without noticeable defects. The floor must be fairly leveled. Concrete floor is the best foundation. It provides a rigid base and minimizes vibration from adjacent machines. The floor strength must be tested. The testing method: place a level on the floor and put the machine on installation position, if the bubble shows appreciable deflection, the floor must be reinforced. When determining the position of installation, leave a space on the left, right, front and back of the machine in accordance with its overall dimension and installation dimension of the machine so that the operating and repairing is convenient. If you use our stand (optional accessory), please, make a mark and drill eight holes in the eight fitting hole position of the base according to the fitting dimension of the stand. Cover eight foundation bolts in the base (note position precision when determine the fitting hole position). Put the stand on the base, connecting to the eight foundation bolts, then place two adjustable iron spacers in each, down face of front, back of two stands (in order to increase the touched space, please stagger the position of front and back adjustable iron spacer). Fix the connecting block of left, right of stand, fit the stand on the base. At last, lift the lathe on the stand and connect and fix the lathe to the stand by using nuts and bolts. When fitting the lathe directly on the base, firstly, in accordance with fitting dimension, mark and drill holes in the base of the six fitting hole position of the lathe. Cover six foundation bolts in the base. Place two adjustable iron spacers on the base in the front and back of the spindle box position and place one adjustable iron spacer on the base in the cross direction of the tailstock position, then lift the lathe on the adjustable iron spacers.

9 Fitting dimension without stand 5.2 LIFTING Lifting the lathe as the following figure shows. Put the mats in which the lifting tools connect before lifting the lathe, to avoid damaging the machine s surface. The lathe net weight 330kg (728lbs), stand weight 60kg (32lbs). You must keep the machine in balance to avoid tilting. The carriage, tailstock and other sliding parts of the lathe are locked before leaving factory. Don t loosen these when lifting and should inspect to confirm whether they are locked or not in order to prevent the parts from sliding. Carefully install the machine on the base or stand with bolts and nuts. 5.3 CLEANING Prior to shipment, all machines and their finished surfaces are coated with antirust oil to protect and prevent rusting. Before moving the carriage or tailstock, use multipurpose cleanser to remove the rust preventive coating. Use a brush and the cleanser to clean the ways of any residue or rust preventive coating. Such care in the cleaning will ensure the removal of any foreign particles and prevent the way from rusting or damaging. Lubricate the ways after you are done cleaning.

10 6. LEVELING The lathe should be kept perfectly leveled at all times. Leveling procedure: A. Longitudinal leveling After the bedways are dry, remove the base screw. Place a 6 precision machinist level over working table in a longitudinal direction (bed length direction). Move the working table at the headstock end along bed length direction. Level and adjust the adjustable iron spacer, to obtain a good reading. Then move the working table to the tailstock, adjust the screw of the adjustable iron spacer until the level obtains the same reading as on the headstock end. on the headstock end on the tailstock B. Cross leveling Put the level on the working table along cross direction 3 (bed width direction). Move the working table to the headstock end along bed length direction. Take a reading, then move the working table to the tailstock end. The reading at this end must be exactly the same as the other end. If the reading is not same, adjust the screw of the adjustable iron spacer to get the same reading. On the headstock end on the tailstock end The adjustments at one end will affect the reading of the other, so that leveling procedure should repeat many times, making necessary adjustments using the staff ruler and the iron spacer. After the adjustments are made, turn down the foundation bolt slightly, until they rest under slight tension. The tension should be such that it does not change the Level reading. Recheck level after fixing the bolt; if necessary, make minor adjustment. After the machine has been put to use for a period of time, check level to observe if the original adjustments exist. Make adjustments as mentioned above if necessary. (Make an erasable mark at one end of the Level to keep the same direction for every reading).

11 CAUTION: THE LOW PRECISION SPIRIT LEVEL MUST NOT BE USED. SCHEDULE OR PERIODICLY LEVEL CHECK AS A PART OF YOUR MAINTENANCE SCHEDULE. 7. LUBRICATION CHART CAUTION: LUBRICATION IS AN IMPORTANT FACTOR OF MACHINE MAINTENANCE. THE QUANTITY OF LUBRICATION OIL MUST BE MODERATE. IF LUBRICATION IS INSUFFICIENT, IT WILL AFFECT THE PRECISION OF THE MACHINE, AND DAMAGE THE MACHING. IF LUBRICATION IS TOO MUCH; IT WILL BE WASTED AND MAKE THE WORKING AREA MESSY AND UNSTABLE. IT IS SUITABLE FOR THE QUANTITY OF THE LUBRICATION OIL NOT TO OVERFLOW OR COME OFF.

I: WHILE MAKING ANY ADJUSTMENTS, REPAIRS OR MAINTENANCE TO THE MACHINE, CUT THE POWER OFF FOR YOUR SAFETY. 8.2 HEADSTOCK The main spindle is driven by gears; it has three groups of sliding gears which position can be changed by operating lever (). The machine is equipped with a belt from the motor to the spindle pulley. The tension of the belt has been adjusted properly in factory. It is advised to check the tension before starting the machine. The belt should depress about /2 inch by normal finger pressure, tightening the belt will damage the bearings. A loose belt will wear easy and slide. When necessary, adjust the belt tension and adjust the bolt under the motor bracket to leave the motor in a proper position and the belt with proper tension. The oil in the headstock should be changed regularly. First, change the oil after you continue using for 5 days. Second, change it after 45 days and then change it every six months or once a year. It has a hole under the headstock and has a screw cover on it. Remove the screw; the oil in the headstock will flow out. After it is drained, you should clean the inside of the headstock using gas oil or kerosene. Then pour the clean lubricating oil in the headstock until the level reaches the red line in the oil gauge. CAUTION: AT ALL TIMES, THE OIL IN OIL RESERVOIRS MUST BE MAINTAINED. IF NOT, PLEASE ADD OIL ACCORDING TO OIL GAUGE. 8.3 SPINDLE SPEED Main spindle can shift 9 different speeds by changing the lever according to brand showing. Proceed as follows: ) Move the control lever to middle position, and turn the motor off; 2) According to speed chart, move the two levers (A), (B), point arrowhead in the direction of the line A, B, C, or, 2, 3, which shows on the name plate. When moving the lever you will see it is difficult. You may move the chuck by hand, to engage the gear.

14 CAUTION: DON T CHANGE SPEED WHEN THE SPINDLE IS RUNNING. 8.4 MAIN SPINDLE ROTATION Starting, stopping, forward and reverse of spindle can be made merely by the control lever. When using the control rod, pull the lever in the headstock direction, then pull up and down. Control lever on the top position Control lever in the middle position Control lever in the bottom position Moving the control lever down the spindle will be forward rotation. Control lever up and the spindle will be in reverse rotation. Control lever in the middle will make it stop. If the motor is one phase and you need to change the direction of the spindle, please move the control lever from one side to the middle, till the motor stops. Then move up or down. If you move the control lever from one side directly to another side, the direction of the spindle won t change. 8.5 GEAR BOX Quick-change gear system, designs the rate of the spindle to lead screw and feed rod when it is used to cut thread or external turning and facing. Quick change gear box is controlled by two handles. Handle () exits A, B, C, three positions. Handle (2) has, 2, 3, three positions. Handle (3) has three positions which is left middle and right. Handle to the left is used for external turning, internal turning and facing. The handle to the middle is parking. Handle to the right engages leadscrew for cutting thread. This machine can be used to use to cut metric and standard threads, when handles () and (2) are positioned in the corresponding position. Please change gears A, B, C, or D. when necessary. ) Gear changing handle 2) Gear changing handle A) Gear B) Gear 3) Feed rod and leadscrew changing handle C) Gear D) Gear

15 Half nut must be kept engaged to leadscrew at all times, when the thread is being cut. Every time you are finished cutting, move tool back and reverse the motor. Then take the tool to the start-cutting position and begin the next process. Continue the process until you have completed the threads. CAUTION: DO NOT CHANGE THE HANDLE () (2) (3) WHEN THE MACHINE IS RUNING

16 B. Table for inch lead screw. 8.6 CARRIAGE The function of the carriage is firmly to support the tool post and carry it, by moving in longitudinal and cross direction. 8.6.Power feed For external turning and facing, turn lever (28) on the gear box to left to make the feed rod rotate. To power feed in longitudinal direction, up engage the cross/longitudinal feed lever (A). To power feed in a cross direction, down engage the cross/longitudinal feed lever (A) in the

17 middle and engage the half nut. If done correctly, you will achieve the lead screw rotating and the carriage to move left and right. While the cross/longitudinal feed lever is in the feed position, the half nut lever (B) can be engaged, safety interlock mechanism will prevent simultaneous engagement of (A) and (B). For threading, put the lever (28) A B on the gear box to the right. Then move the cross/longitudinal feed lever (A) to the middle and engage the half nut. CAUTION: DO NOT FORCE THE HALF NUT LEVER WHILE ENGAGING WITH THE LEAD SCREW. When you power feed the spindle is what decides which way to engage the carriage. When the spindle rotates clockwise, the carriage moves left. Conversely to the right THREADING DIAL When the pitch proportion of the lead screw and work piece thread is not integer times and need to open the half nut while cutting, it is necessary to use the threading dial to control tools and prevent the mixed screw. The threading dial is located on the right or left side of the apron. It performs the important function of indicating the proper time to engage the half nut lever, so that the tool will enter the same groove of the thread on each successive cut. The dial is marked with lines numbered and in between are lines with no numbers. These are half lines and are called unnumbered lines. The dial engaged with the leadscrew, causes rotation of the dial, and a single line is marked on the housing of the threading dial (fixed line). The instruction plate riveted on the threading dial shows the selection and sequence of matching the revolving lines with the fixed line. For thread cutting, engage the half nut with the appropriate numbers shown on the scale column of the threading dial plate. -4 on the scale means the half nut can be engaged on any of the numbered lines For each successive cut, only numbered lines must be used. - 3/2-4 on the scale means the half nut can be engaged on and 3 or 2 and 4. For successive cuts, when you engage the half nut on the numbered line or 3 you engage the half nut on the numbered line 2 for the first cut. After that, the half nut will be engaged on the numbered line 2 or means the half nut just be engaged on any line, numbered or unnumbered. If the half nut engages with the lead screw all the time while cutting the thread, you don t need to use the threading dial. After cutting, back the tool and reverse the motor, then move the tool to the last start cutting position and make the next cut. 8.7 FOUR POSITION TOOL POST

18 The main function of tool post is to fix tool, if necessary. Tool post may fix more than one tool (at most 4). Tool thickness must be less than tool groove. When installing a tool again, you should confirm the tool head direction to the work piece revolving center line. Use an iron spacer to adjust. After adjusting correctly, please fix the tool. If turning the tool post, turn the tool post locking handle counter clockwise to loosen the locking handle and turn the tool post to the position you need. Then turn the tool post lock handle clockwise to lock tool post. 8.8 COMPOUND SLIDE Using the compound slide can cut tapers. When cutting tapers, please loose the screw on the saddle, around the compound slide. Face the graduated line towards the graduating number on the saddle. Then fix the screw, around the driving handwheel. The tool post moves the tool, and now there is an angle between the traveling line and turning line of spindle. Now you can turn a taper. 8.9 TAILSTOCK The tailstock slides along the bedways freely and can be locked in any position by the clamp lever (4). There is an end pin to stop the tailstock sliding down. Rotating the tailstock handwheel (5) can slide the quill. The quill can be locked by the quill lock lever (3). Before leaving the factory, it will be sure that it is the same line between the tailstock center and spindle center. For cutting small tapers, you must loosen the clamp lever (4) in advance and adjust the set over screw (). It makes the deviation between spindle center and tailstock center. After make sure you lock the clamp lever and start machining. Once you re finished, set the tailstock back in the same way when doing the external turning by using the tailstock center and get a taper work piece. As mentioned above, adjust the two set over screws () and back up the tailstock correctly to eliminate the taper. When correcting, use a precise cylinder to connect the two centers of spindle and tailstock. Then place a meter on the worktable and make it s center head contact to the cylinder side center line. When you move the worktable to the end of headstock, take a reading from the meter, then move the meter to the tailstock end, otherwise use the same way as mentioned above to make adjustments to get the same reading at both ends. 9. PROTECTION GUARDS The lathe can be equipped with several safety protection guards. Protect your body not to be hurt and make it a safe work environment. These guards include; chuck cover with micro switch system; tool post cover with micro switch system; pulley cover with micro switch system. Etc.
