To load a workpiece, do these steps:
1.
With the chuck key, open the jaws so the workpiece
lays flat against the chuck face and jaw step or
fits in the through hole. For jaw and work holding
options, see
Figure
27.
2.
Slowly turn the workpiece, and turn the chuck
wrench until the jaws make contact with the
workpiece.
3.
Turn the chuck by hand to make sure you have even
contact with all three jaws and the workpiece is not
off center.
• If the workpiece is off center, loosen the jaws and
adjust the workpiece.
• If the workpiece is seated correctly, tighten the
jaws.

Loading a workpiece.
If the workpiece protrudes more than 2.5 times its
own diameter, support it with a center, and possibly
a steady rest. Otherwise the workpiece can deflect or
come out of the chuck, causing injury.
Securely clamp your workpiece and
remove the chuck key! Thrown objects
from a lathe can cause serious injury or
death to the operator and to bystanders
many feet away.
