Spindle Break-In

Before placing operationql loads on the spindle, complete this break-in procedure to fully distribute lubrication throughout the bearings and ensure trouble-free performance.

Failure to complete the spindle break-in process may lead to premature failure of the bearings—this will not be covered under warranty.

To perform the spindle break-in procedure:

1.Make sure the spindle is completely stopped, then set spindle speed to 90 RPM (refer to Page 26 for detailed instructions).

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

2.run machine for a minimum of 10 minutes.

3.repeat Step 2 for each spindle speed, work- ing to progressively higher speeds.

Note: If the machine is new, we recommend changing the headstock oil while it is still warm and any particles from the manufacturing process are still in suspension (refer to Page 31 in the Lubrication subsection for detailed instructions).

The spindle break-in is now complete!
