QUICK RELEASE COLLET REMOVAL AND
REPLACEMENT
(Mounting Manifold Assembly)
If collet or O-rings become damaged, they can be
removed and replaced. To remove the collet, use
a flat blade screwdriver or needle nose pliers. If
using the screwdriver, lift collet with fingers and
place screwdriver blade under the head. Pry
up in several places if necessary until removed.
If using the pliers, grasp the head between the
inside and outside diameter and pull straight out
or by pulling with a rocking motion.
Remove the O-ring with a plastic pick device. Do
not scratch or nick the sealing surfaces.
To replace O-ring and collet, lubricate the O-ring
with petroleum jelly and insert into hole and make
sure it lies flat on its seating surface. Align the
collet with the hole and push straight in. Some
collets are tighter than others by design and may
require a rocking motion while pushing.
