Be aware that machine components can shift 
during the shipping process. Pay careful 
attention 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.
Spindle Break-In
The high-quality bearings and gears used in the 
mill are manufactured to very close tolerances. 
However, this does not guarantee perfect 
dimensional mating of the bearing components or 
exact meshing of gear teeth. Before operational 
stress is placed on these and other moving parts 
in the mill, complete this break-in procedure to 
conform these components to one another and 
ensure trouble-free performance from the mill.
To perform the spindle break-in procedure:
1.
  Successfully perform all the steps in the 
Test Run section beginning on Page 25.
2.
  Make sure the spindle is at a complete stop.
3.
  Set the spindle speed to the low range 
(refer to Setting Spindle Speed Range 
beginning on Page 37 for detailed 
instructions).
4.
  Start the spindle rotation at a medium speed 
and let the mill run for 20 minutes.
5.
  Stop the spindle rotation and allow the 
spindle to come to a complete stop by itself.
6.
  Set the spindle speed to the high range, then 
start the spindle rotation at a medium speed 
and let the mill run for another 20 minutes.
7.
 
Stop the spindle rotation, and turn the mill 
OFF.
The spindle break-in of the mill is now complete!
Complete the spindle bearing break-in 
procedure to avoid rapid deterioration of 
spindle components when the mill is placed 
into operation.
Since the mill head was rotated parallel to 
the table for shipping purposes, you will need 
to tram the spindle with the table if your first 
cut requires a 90° alignment. Refer to the 
Tramming Spindle section on Page 33 for 
detailed instructions.
