Test Run & Break-In
NOTICE
NEVER shift lathe gears when lathe is operating, and make sure both the half-nut lever and the feed lever are disengaged before you start the lathe! Otherwise the lathe will feed the apron into the chuck or tailstock causing severe lathe damage.
The purpose of the test run is to make sure the lathe and its safety features operate correctly.
To begin the test run & break-in procedure:
1.Make sure the lathe is lubricated and the headstock oil level is full. Refer to Lubrication on Page 33.
2.Make sure the chuck is correctly secured to the spindle. Refer to Mounting Chuck and Faceplate on Page 20 for details.
| 3. Disengage the half-nut lever and the feed |
| lever (Figure 10). | |
| 4. Connect power to the machine. |

5.Rotate the red stop/RESET button (Figure 11) clockwise so it pops out, and make sure the motor direction selector points to STOP.
6.Move the speed levers to B and 1 so the spindle will rotate at 70 RPM (Figure 11).

7.Push the POWER START button, then move the spindle rotation ON/OFF lever (Figure 10) down until the chuck begins to turn. The top of the chuck should turn toward you.
—If you hear squealing or grinding noises, turn the lathe OFF immediately and correct any problem before further operation.
—If the problem is not readily apparent, refer to Troubleshooting on Page 35.
8.Push the emergency stop button.
—If the lathe does not stop, turn the lathe OFF with the spindle rotation ON/OFF lever, and disconnect the lathe from power. Refer to Troubleshooting on Page 35 for correction.
9.Return the spindle rotation ON/OFF lever to STOP, reset the emergency stop button, restart the lathe, and let the lathe run for a minimum of 10 minutes in both directions.
10.Turn the lathe OFF, and move the speed levers to C and 1 so the spindle will rotate at 200 RPM. Run the lathe in both directions for 10 minutes.
11.Repeat Step 9 for the remaining RPM ranges progressively increasing in RPM. When these steps are complete, the lathe is broken in.
12.Drain and refill the lubricant in the headstock with Mobil DTE® Oil or an equivalent. Refer to Lubrication on Page 33 for steps and apron oil change interval.
