— 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

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.
7. Verify that chuck fits spindle properly by
checking for any gaps between mating sur-
faces.
—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, 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 problem
persists, contact our Tech Support.
5. Incrementally tighten camlocks in criss-cross
or star pattern to ensure that chuck seats
evenly against spindle.
6.
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.
