Test Run and

Spindle Break-in

The Model G0619 spindle speed can be set from 100–1750 RPM. You must follow the proper break-in procedures to ensure the spindle bear- ings break-in and seat before putting any milling load on the machine.

To test run and break-in the spindle bearings:

1. Do all lubrication procedures highlighted in Lubrication in Section 6: MAINTENANCE on Page 25.

2. Make sure there are no obstructions around or underneath the spindle.

3. Remove the drawbar if there is no arbor or collet in the spindle.

Low

4.Make sure all switches are OFF and connect the mill/drill to the power source.

5. Turn the main power switch ON, and push the START button on the control panel. The spindle will begin to turn at a low RPM.

6. Now push the + button until the mill/drill reaches approximately 600 RPM, then let it run for a minimum of 10 minutes.

—If you suspect the mill/drill is not working cor- rectly, shut the mill/drill OFF , disconnect it from power, and use the Troubleshooting table on Page 26 to correct the problem before proceeding further.

—If the mill/drill is running smoothly, proceed to Step 7.

NOTICE

DO NOT leave the area while break-in pro- cedure is under way. You must be ready to stop the machine if any problem occurs.

7. Increase the speed to 1000 RPM and let it run for another ten minutes.

8.Increase the speed to 1750 RPM and let it run for another ten minutes.

9. Turn the mill/drill OFF.

10.Set the spindle to rotate in the opposite direc- tion, and let it run at 1750 RPM for another ten minutes.

NOTICE

Failure to follow start up and spindle break- in procedures will likely cause rapid deteri- oration of spindle and other related parts.
