13. Press the GREEN Motor ON button. The spindle should

turn forward, counter clockwise, viewed from the tailstock

end.

14. Check the emergency function by pressing the E-Stop

button. The motor should stop.

If this doesn’t happen,

the E-stop function is defective, and needs attention.

15. Reset (twist) the E-Stop button to restore power.

16. Check that the chuck guard switch stops the motor when

the guard is swung up.

17. Check that the belt cover safety switch stops the motor

when the belt cover is removed, Figure 1-1.

18. Press the RED Motor OFF button, Figure 1-4. The motor

should stop.

OPTIONAL TEST RUN PROCEDURE

With the spindle stationary, use the handwheel to run the sad-

dle back and forth a few times from headstock to tailstock (if

the handwheel cannot be turned, check that the power feed

lever and half-nut lever on the apron are in neutral, Figure 1-3).

With the power feed lever still in neutral, run the cross-slide

front to back a few times.

1. With the power feed and half-nut levers in neutral, run the

ALIGNING THE LATHE

The most important attribute of a properly set up lathe is its

ability to “machine parallel”, to cut a cylinder of uniform diame-

ter 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.

spindle for a few minutes, forward and reverse, at a selec-

tion of speeds in both speed ranges (transfer the Vee belt

from inner to outer pulley grooves to change speed range).

The 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.

3. Power-feed the saddle and cross-slide, Figures 1-5, and

1-6, stopping well before end limits or other obstructions.

4. After the initial test run, with 20 additional hours of machine

time, drain and refill the gearbox and apron with the lubri

cants specified in Section 4.
