Incrementally tighten camlocks in criss-cross
or star pattern to ensure that chuck seats
evenly against spindle.

When chuck is fully seated and all camlocks
are tight, verify that cam line is between the
two "V" marks on spindle nose, as shown in
following figure.
Cam line between "V"s
Figure 23. Cam line positioned between the "V"
marks after the camlocks are fully tightened.
— If cam line is NOT between "V" marks when
camlock is tight, stud may be installed at
incorrect height. To fix this, adjust stud
height as shown in following figure. Make
sure to re-install stud cap screw afterward.
— If adjusting stud height does not correct
problem, try swapping stud positions on
chuck.

Verify that chuck fits spindle properly by
checking for any gaps between mating
surfaces.
— If there is not a gap, proceed to Step 8.
— If there is a gap, remove chuck, re-clean
mating surfaces carefully, and re-install.
If problem persists, contact our Tech
Support.
8.
Verify that chuck/spindle tapers are seat-
ed firmly together by removing chuck, per
Chuck Removal instructions on following
page, and pay close attention to how easily
tapers release.
— If it was necessary to bump chuck or use
a mallet to release tapers, then they are
seating together properly.
— If tapers released easily with little interven-
tion, they are not seated together firmly as
required. Remove chuck, re-clean mating
surfaces carefully, and re-install. If prob-
lem persists, contact our Tech Support.

Registration Marks

Lightly stamp registration marks across the mating
seams of chuck components. These marks will
help you re-install the chuck in the same position
after removal, which ensures consistent chuck
balance and turning results, and allows the
same camlocks and studs to operate together for
consistent locking and unlocking.
