Reversing Jaws
the included 3-jaw scroll chuck features revers-
ible hardened steel jaws (see

move in unison to converge evenly against con-
centric workpieces.

Low Side
using the stamped numbers, the jaws are installed
in numerical order in the jaw guides (see
figure

To reverse the jaws:
1. disCoNNECt lathE FroM poWEr!
2. use an appropriate device to protect the
ways during the installation process (refer
to
Installation & Removal Device on page
20).
3. insert chuck keys into holes in chuck and
outer ring (see
figure 20). hold chuck key
stationary while turning outer ring counter-
clockwise, then back jaws out and remove
them.
4. use mineral spirits to clean debris and grime
from jaws and chuck jaw guides.
When installing the jaws, it is important to make
sure they are installed correctly. incorrect installa-
tion will result in jaws that do not converge evenly
and are unable to securely clamp a workpiece.
all of the tall ends of the jaws—or all of the low
ends—should face each other when installed (see
figure 18). the jaws should be oriented so they
correctly hold the workpiece (refer to
figure 22
on
page 23).
Each end of a jaw is stamped with a number (1, 2,
or 3), as shown in
figure 19.
