13.
Check the emergency function by pressing the
E-Stop button. The motor should stop.
If this
doesn’t happen, the E-stop function is defec-
tive, and needs attention.
14.
Reset (twist) the E-Stop button to restore power.
15. Return the motor control lever to OFF, mid-travel.
The motor should stop.
16. Shift the motor control lever UP. The spindle should
reverse, clockwise rotation, viewed at the chuck
(nose) end.
OPTIONAL TEST RUN PROCEDURE
Run the spindle for a few minutes, forward and reverse,
at each of the 6 speeds available with the low speed Vee
belt configuration, then repeat with the Vee belt changed
to high speed.
Note:
In initial tests the carriage and cross slide should
first be exercised manually, then under power.
After the initial test run, with 10 additional hours of ma-
chine time, the headstock should be drained and refilled.
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
Section 4, Servicing the Lathe.
