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.
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!
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.
Inspections & 
Adjustments
the following list of adjustments were performed

Be  aware  that  machine  components  can  shift 
during  the  shipping  process.  pay  careful  atten-
tion to these adjustments during operation of the 
machine. if you find that the adjustments are not 
set according to the procedures in this manual or 
your personal preferences, re-adjust them.
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).
Failure to complete the spindle break-in 
process may lead to premature failure of the 
bearings—this will not be covered under 
warranty.
