27.Use the coolant pump switch on the control panel to start the pump, then open the valve at the base of the nozzle. Verify that the coolant flows from the nozzle, then close the valve and turn the pump OFF.

Congratulations! The test run is complete. Perform the following Spindle Break-Inprocedure.

Spindle Break-In

Before subjecting the lathe to full loads, it is essential to complete the spindle break-in process as described below. This will ensure the best results and maximum life of the precision components inside the lathe.

The break-in procedure must be performed in succession with the Test Run procedure described in this manual, because many of the test run steps prepare the lathe controls for the break-in process.

Important: Do not perform the break-in procedure independently from the Test Run section—serious damage could occur to the lathe if the controls are set differently than instructed in that section.

Do not leave the lathe unattended during the Spindle Break-In procedure. If your attention is needed elsewhere during this procedure, stop the lathe and restart the procedure later from the beginning.

To perform the spindle break-in:

1.Successfully complete the Test Run procedure beginning on Page 32.

2.Using the spindle speed levers to set the spindle speed, run the lathe for ten minutes at each of the following speeds: 50, 150, 500, and 1600 RPM.

Note: If necessary, refer to Setting Spindle Speed on Page 54 for detailed instructions.

3.Use the foot brake to stop spindle rotation, then reverse spindle rotation with the spindle lever, then run the lathe at 1600 RPM for 10 minutes.

4.Use the foot brake to stop spindle rotation, then run the lathe at 150 RPM for ten minutes with the gearbox range lever (Figure 27) on the headstock in the L (low) position, and then run the lathe for another ten minutes with the lever in the H (high) position.

5.While the oil is still warm and any metal particles may still be suspended in the oil, change the headstock and gearbox oil (refer to Lubrication beginning on Page 68 for detailed instructions).

6.Check, and if necessary, re-tention the V-belts (refer to V-Beltson Page 80 for detailed instructions).

Congratulations! The spindle break-in is complete.

Adjustments

For your convenience, the adjustments listed below have been performed at the factory. However, because of the many variables involved with transporting the machine during shipping, we recommend that you at least verify the following adjustments to ensure the best possible operational results from your new machine.

Step-by-step instructions for these adjustments can be found on the pages referenced below.

Factory adjustments that should be verified:

•Tailstock alignment (Page 45).

•Compound and cross slide backlash adjustment (Page 77).

•Gib adjustments (Page 78).
