Spindle break-In

Before placing operational 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 Setting Spindle Speed on Page 28 for
detailed instructions).
Do not leave this machine unattended during
the Spindle break-In procedure. If your
attention is needed elsewhere during this
procedure, stop the machine 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 32 in the
Lubrication subsection for detailed instructions).
the spindle break-in is now complete!
