An inspection to find some damaged portion which might have been caused by shock during the transportion, all surfaces of exposed machined are coated with a antirust liquid. Before moving turret and cross-slide, leadscrew, rack……etc, these surface should be thoroughly cleaned down the antirust liquid by soft brush and solvent. This is very important since it prevents any dirt and grit which may have accumulated on the antirust liquid from working under the sliding members and causing undue wear.

CAUTION ： DO NOT USE COMPRESSED AIR TO CLEAN, WHICH WILL REDUCE THE MACHINE'S LIFE.

It is very important to obtain machine's accuracy that foundation and installation of machine are need. For the reason, a perfect foundation with proper thickness and pressure-enduring space must be provided. (In general case, a thickness of 30mm (12") is considered to be enough). The machine has six adjustable feet at the corner of the pedestal for leveling machine, it is necessary to use shims under pedestal feet. When adjust foot loosen set screw, then raiser or lower foot with a pin wrench so that all six feet rest on the floor. Tighten set screw to setting.

Turn cam switch A (Figure 2) to "OFF" position, and loosen screw "B" (Figure 2), open the switch case cover connect your supply power source lines and ground connection to "C" (Figure 3). Secure switch case cover, turn cam switch "A" (Figure 2) to "ON" position.

Place lever "D" (Figure 4), on lower position, pull out lock pin "E" (Figure 4) and push "START" button "C" (Figure 5), place lever "G" (Figure 4) on forward position. Spindle should rotate counterclockwise when viewed from turret end. If the spindle does not turn in the correct direction, push "STOP" BUTTON "H" (Figure 5) to stop machine, then, turn off the main power and interchange any two lead lines. This is to prevent changed speed motor from run in reverse at beginning.

CAUTION ： DO NOT OPERATE SPEED CHANGE MECHANISM UNTIL SPINDLE ROTATION HAS BEEN CHECKED.

Special care on lubrication should be taken to maintain the life and performance of the machine for a long period. For the reason, must used a high quality or equal oil, and checked periodically to assure there are filled to the proper lever on the oil gage, the method as below ：

To change spindle speed, first, start spindle and release "H" (Figure 7), then turn the cam switch lever "S" (Figure 7) to the "FORWARDD" or "REVERSE" position, and push lever "D" (Figure 8) to the "LOW" or "HIGH" position then push lever "G" (Figure 8) to the start position, turn "F" (Figure 7) to increase speed.

※ CAUTION：
FOR PROPER LUBRICATION OF DRIVE RUN THROUGH COMPLETE SPEED RANGE DAILY.

The headstock spindle is mounted on precision preloaded ball bearings, the bearing are grease-packed for life and require no further lubrication.

The collet closer in place without using collet when running the machine, that may damage the collet closer. So must remove the collet closer when using jaw chucks, face plates, fixture plates or other nose type fixtures.

When cleaning the machine need to remove the collet closer for prevent leading of chips between collet tube, and inside of spindle at rear end and collet threads. The methods of removal is described below ：

1. First, pulling up and out link pin “L” (Figure 11) which is easy to pull out and up with fingers.
2. Remove the collet closer as shown figure 13. Pull straight out end of spindle. Do not turn adjusting nut "N" (Figure 13), it is keyway to spindle. And do not remove collet closer by removing screw "S" (Figure 12) because these screws are adjusted at the manufacturer for proper operation of collet closer.

Figure 11-Collet Closer Removal Figure 12-Collet Closer Adjustment Figure 13-Collet Closer Removal

Replace the collet closer first, must clean inside of the headstock spindle and outside diameter at rear of spindle where located adjusting nut "N" (Figure 14), apply a film of light oil on there. Do not force adjusting nut "N" (Figure 14) on spindle. If adjustment nut "N" (Figure 14) goes on tight, remove and check for burrs or scratches, then clean collet closer tube inside and outside apply a film of light oil on slip surface "T" (see figure 15) of the collet closer tube, replace collet closer and insert link pin "L" (figure 15).

1. Before using the collet or step chuck and closer to the spindle, collet or step chuck and spindle should be clean.
2. Push in lock pin "E" (Figure 16). To engage lock pin, turn spindle by hand till lock pin enter notch to lock.
3. Closer adjusting finger "F" (Figure 17) by pressing down at point "P" (Figure 17).
4. Place collet closer tube on collet or step chuck until engaged. To turn the collet closer tube and turn the shell guard "G" (Figure 17) forward with operator's left hand while holding the collect or step chuck on place with operator's right hand.
5. Place a work piece in collet or step chuck.
6. Place lever "L" (Figure 17) to the extreme left or closed position. Turn shell guard "G" toward operator until the collet touch the piece.
7. Place lever "L" (Figure 17) to the right (released) position. And turn shell guard "G" (Figure 17) toward operator, move the adjusting finger "F" (Figure 17) advances two notches on the adjusting nut "N" (Figure 18) and close adjusting finger "F" (Figure 17).
8. Test collet closer for tension on work piece. If the gripping pressure required additional, open adjusting finger "F" (Figure 17) and turn shell guard "G" (Figure 17) toward operator. The gripping pressure require less, turn shell guard "G" (Figure 17) away operator. (see figure 17).
