Spindle Break-In
The high-quality bearings and gears used in this
lathe are manufactured to very close tolerances.
Before subjecting the lathe to full loads, it
is essential to complete the spindle break-in
process as described below. This will ensure the
best results and maximum life of the precision
components inside the lathe.
The break-in procedure must be performed
in succession with the Test Run procedure
described in this manual, because many of the
test run steps prepare the lathe controls for the
break-in process.
Important: Do not perform the break-in
procedure independently from the Test Run
section—serious damage could occur to the lathe
if the controls are set incorrectly when the break-
in procedure is started.
For your convenience, the adjustments listed
below have been performed at the factory.
However, because of the many variables involved
with shipping, we recommend that you at least
verify the following adjustments to ensure the
best possible results from your new machine.
Step-by-step instructions for these adjustments
can be found on the pages referenced below.

Adjustments
To perform the spindle break-in:
1. Successfully complete the Test Run
procedure beginning on Page 28.
2. Set the spindle speed for 40 RPM (refer to
the Setting Spindle Speed subsection on
Page 51 for detailed instructions).
3. Run the lathe for 10 minutes.
4. Turn the lathe OFF and wait until the
spindle is completely stopped.
5. Repeat Steps 2–4 for each of the remaining
15 spindle speeds.
6. Set the spindle speed to 40 RPM and let the
lathe run for a final 15 minutes to allow it to
cool down, then turn the lathe OFF.
7. Change the oil in the headstock, quick-
change gearbox, and apron reservoirs as
instructed in the Lubrication subsection on
Page 67.
8. Check and, if necessary, re-tension
the V-belts as instructed in the V-Belt
subsection on Page 80.
Congratulations! The spindle break-in is
complete.
Do not leave the lathe unattended during the
Spindle Break-In procedure. If your attention
is needed elsewhere during this procedure,
stop the lathe and restart the procedure later
from the beginning.
