slightly drawn in
the external
shape of the
collar and sits
securely.

Joint clamp
(306) is too
loose and can
slide off.

3. Make sure that the joint clamp (306)
lies in the collar groove along the
entire circumference of the joint collar
(308).
4. Slowly swivel the clamping tool
approximately 60° upward until the
cutting hook engages behind the joint
clamp seal (
see next image).
5. Manually tighten the pressure screws
until the joint clamp is securely
clamped.

6. Rotate the pressure screw in the
clockwise direction with a screw
wrench or ratchet until the joint clamp
is sheared off.
Caution!
If the joint clamp is raised slightly
on the cut side, counteract this by
carefully rebending it. Hammering
or striking the joint clamp seal is
not acceptable because this may
cause damage to the collar!
Notice!
The clamping tool cannot be used
to shear off joint clamps made of
Hastelloy.
►
After canting at the joint clamp
seal, use metal shears to
shear off the joint clamp;
deburr the cut edges (
see
following image).
10.2.4.2 Tightening with clamping tool
PoK-It II
If using the PoK-It II clamping tool, swivel the
clamping tool after tightening in order to cant
the joint clamp (306) at the joint clamp seal in
such a way that the clamp cannot slide through
the seal. After canting at the joint clamp seal,
use metal shears to shear off the joint clamp;
deburr the cut edges (
see following image).
