Spindle Break-In
Before placing operational loads on the spindle,
complete this break-in procedure to fully distrib-
ute lubrication throughout the bearings and help
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.
DISCONNECT MACHINE FROM POWER!
2.
Set up vertical spindle for lowest spindle
speed (refer to Spindle Speed, beginning on
Page 31 for detailed instructions).
Do not leave the 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.
3.
Connect machine to power, and run vertical
spindle for a minimum of 5 minutes.
4.
Repeat Step 3 for each spindle speed, work-
ing to progressively higher speeds.
5.
Repeat Steps 2–4 with horizontal spindle.
6.
Check tension of all V-belts, and retension
if necessary (refer to V-Belt Service on
Page 50 for detailed instructions).
The spindle break-in is now complete!

Inspections &
Adjustments
The following list of adjustments were performed
at the factory before the machine was shipped:
•
Gib Adjustments ..............................Page 52
•
X-Axis Leadscrew Backlash ........... Page 53
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.
Since the head has been moved around for
shipping purposes, you will need to tram it
so that the spindle is perpendicular to the
table. Refer to the Tramming the Mill section
on Page 34 for detailed instructions.
After the first 16 hours of use, the V-belts
will stretch and seat into the pulley grooves.
The V-belts must be properly retensioned
after this period to ensure proper power
transmission and avoid reducing the life of
the belts. Refer to V-Belt Service on Page 50
for detailed instructions.
