3 Jaw Scroll Jaw Chuck Operation
The standard Haas option for the TL series lathe for part holding is a 3-jaw scroll plate chuck, that
is key operated from the outer diameter of the chuck. Simply rotate the chuck key in a clockwise
direction to draw the jaws of the chuck closer to the chuck center, and counter-clockwise to
move the jaws away from the chuck center. The configuration of the chuck jaws and part holding
is up to the operator to decide which is best for that particular project.

CAUTION: The chuck key comes equipped with a spring on the end to prevent accidentally starting
the spindle with the chuck key engaged to the chuck. DO NOT REMOVE THE SPRING FROM THE
KEY!!!!! Starting the spindle with the chuck key engaged will lead to extensive machine damage
and potential physical harm for the operator!
