PREPARATION
Spindle Break-In
Before subjecting the lathe to full loads, you
must break it in so that bearings will fully seat,
gear teeth will find their normal wear pattern,
and lubricant will be worked into the required
areas. Otherwise, the moving components of the
lathe may suffer from excessive wear.
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.
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.
To perform the spindle break-in:
1. Successfully complete the Test Run
procedure beginning on Page 21.
2. Move the spindle switch to the left position,
then run the lathe for ten minutes at each of
the following approximate speeds: 50, 500,
900, 1800, and 2300 RPM.
3. Turn the spindle speed dial all the way
counterclockwise to the minimum and
move the spindle switch to the middle OFF
position.
4. When the spindle has come to a complete
stop, move the spindle switch to the right
position and run the spindle in reverse at
2300 RPM for another ten minutes.
5. Turn the spindle speed dial all the way
counterclockwise to the minimum, move the
spindle switch to the OFF position, and turn
the master power switch OFF.
6. Check, and if necessary, re-tension the
drive belts (refer to Adjusting Drive Belts
on Page 55 for detailed instructions).
Congratulations! The spindle break-in
is complete. Continue with the following
Recommended Adjustments subsection.
For your convenience, the adjustments listed
below have been performed at the factory.
However, because of the many variables involved
with transporting the machine during shipping,
we recommend that you at least verify the
following adjustments to ensure the best possible
operational results from your new machine.
Step-by-step instructions for these adjustments
can be found on the pages referenced below.

Adjustments
The maximum recommended spindle speed is
2300 RPM. DO NOT exceed this for more than
a brief period of time or machine damage may
occur.
