5. Incrementally tighten the camlocks in a criss-
cross or star pattern to ensure that the chuck
seats evenly against the spindle.
6.
When the chuck is fully seated and all the
camlocks are tight, verify that the cam line
is between the two “V” marks on the spindle
nose, as shown in the following figure.

— If the cam line is NOT between the "V"
marks when the camlock is tight, the stud
may be installed at the incorrect height.
To fix this, adjust the stud height as
shown in the following figure. Make sure
to re-install the stud cap screw afterward.
— If adjusting the stud height does not
correct the problem, try swapping stud
positions on the chuck.

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