THEN NEEDING TO ADJUST TOOL, THE MACHINE OR WORKING PIECE, YOU MUST CUT OFF POWER. 8.2 MAIN SPINDLE DRIVING a. Before starting the machine, you should check the tension of belt. The belt should depress about 0mm under normal finger pressure. The tension of the belts can be adjusted by the lever (8). b. Main spindle running, stop, forward and reverse can be realized by shift switch (3). If needing to change main spindle running, please turn the shift switch to middle position, after a moment, then to the opposite side. Or, if turn the switch to another side directly, the direction of main spindle running don t change. c. Loose lock lever, change the belt position in tower pulley, then tighten belt. Now the main spindle can obtain 7 kinds of speed according to the following chart. 0

12 8.3 DRILLING-MILLING SPINDEL DRIVING a. At first, check the protection instrument if effective, then push start switch, pilot light, the machine is awaiting working. Now stop, forward and reverse of drilling-milling spindle can be made by operating the shift switch (9). b. Drilling-milling spindle feeding can be change by lever(3), If need micro feeding, pull out drilling-milling clutch lever(0), then operate lever() to micro feed. c. The speed of drilling-milling spindle can be made by lever(8):push lever to backward, loose belt and change the belt position on the pulley, then push the lever to the front to tighten belt, finally lock lever(8).6 kind of speed can be obtained as the above chart. 8.4 LONGITUDIANL FEED a. HAND FEEDING: Turn the clutch handle () to the middle position, half-nut lever (26) in disengaged position, turn the hand wheel (23), now longitudinal hand feeding can be made. b. AUTOMATIC FEEDING: The half-nut lever (26) in engaged position, longitudinal-cross feed clutch handle (22) in inner position. Now cross auto-feeding can be made. By changing the handle (2) position and gear A,B,C,D, 2 kinds of automatic feed amount can be obtained as follows. (the left chart is for the inch lead

13 screw, and the right chart is for the metric lead screw) 8.5CROSS FEEDING a. Hand feeding can be made by operating the hand wheel (24) directly. b. Automatic feeding: half-nut lever (26) in engaged position. Pull out longitudinal-cross feed clutch handle (22), now cross automatic feeding can go. By changing the handle (2) position and gear A,B,C,D, 2 kinds of automatic feed amount can be obtained as above.(the left chart is for the inch lead screw, and the right chart is for the metric lead screw) 8.6 THRED CUTTING a. Main spindle in low speed, the lever () in left position, Refer to gear chart, adjust gear shift lever (2) properly, half- nut lever (26) in engaged position. Now it can go to cut thread. Different thread pitch (inch, metric) cutting can go by changing the lever (2) and gear A, B, C,D. b. CAUTION: IN CUTTING THREAD COURSE, DON T LEAVE handle (2) OFF RIGHT OR LEFT POSITION. WHEN A KIND OF THREAD NEED MANY TIMES. TURN THE HANDWHEEL (5) TO MAKE TOOL AWAY FROM WORKPICCE, OPERATE THE ELECTRICAL SWITCH TO MAKE MOTOR RUN IN THE OPPOSITE DIRECTION. AFTER FINISHING RETURNING TOOL CONTINUE TO CUT THREADS. DO SO MANY TIMES UP TO FINISHING CUTTING THREADS. 2

14 8.7TAIL STOCK The tail stock can slides along the bed ways freely and can be locked in any position by the lock lever(7). Tail stock barrel position can be adjusted by turning the tail stock hand wheel (5), locked by lock lever (4). Before shipment, it is sure that the tail stock center and spindle center are in the same line. If need to use the tail stock center to cut small taper, you should loose the screw, adjust the two reset screw (6) to make the deviation between spindle center and tail stock center. Now you can start the work.. After finishing proceeding, you should do as the above to move tail stock in original position. When use tail stock to do the external cutting and get a taper, please adjust the reset screw (6) as the above way. Now you can eliminate the taper. 8.8THREADING DIAL Threading dial performs the function of indicating the proper time to engage the half-nut so that the tool will enter the same groove of the thread on each successive cutting. Threading dial is marked with lines numbered , and a single line is marked on the housing of the threading dial (fixed line). The instruction plate (see the following figure) riveted on the threading dial shows the selection of matching the revolving lines with the fixed line. When cutting thread, engage the half-nut at the proper numbers shown on the scale column of the threading dial plate. -6 on the scale means the half-nut can be engage on any of the numbered lines In the first cutting, if engage the half-nut when matching the numbered lines with fixed line, you can engage the half-nut for successive cutting only when matching the numbered lines with the fixed line..4 mean the half-nut can be engaged on.4 for successive cutting. If the half-nut engage with the lead screw all the time while cutting the thread, need not to use the threading dial. In this case, after finishing each successive cutting, firstly back the tool and reverse the motor, then move the tool to the last start cutting position and make the next successive cutting.
