OPTIONAL TEST RUN PROCEDURE
Run the spindle for a few minutes, forward and reverse,
at a selection of the 9 speeds available for the as-shipped
Vee belt configuration. See Section 3 if a different con-
figuration is preferred.
The carriage feed gearbox should also be run at this
time, but first make certain that the leadscrew and feed
shaft oilers at the tailstock end have been lubricated.
Also note:
In initial tests, because the saddle and cross
slide should first be exercised manually, the leadscrew
split-nut should be disengaged — ditto the saddle/cross-
slide power feed lever, Figure -0.
After the initial test run, perhaps with a few additional
hours of machine time, some users drain and refill the
headstock and carriage feed gearbox. Lubricants are
specified in Section 4. Other users prefer to delay this
service action for at least 50 hours of running time. No
specific recommendation is given by the manufacturer.

ALIGNING THE LATHE
The most important attribute of a properly set up lathe
is its ability to “machine parallel”, to cut a cylinder of uni-
form diameter over its entire length. In other words, no
taper.
Leveling of the lathe is a part of this, see earlier in this
section. Equally important is the alignment of the center-
to-center axis with the lathe bed, as seen
from above
.
[Vertical alignment is nowhere near as critical, rarely
a cause of taper unless the lathe is damaged or badly
worn.] For more information see the final pages of Sec-
tion 4, Servicing the Lathe.
