The Locking Screws are located on the Housing and the Headstock.
These Locking Screws are captured in their holes so that they will not come totally
free of the Clamshell.
Separate the Clamshell sections evenly by pulling straight apart.
DO NOT FORCE OPEN.
Secure the Clamshell to the pipe.
Clean the mating surfaces and the contact surface of the Mounting Pads and
the jackscrews on each half of the Clamshell.
Wipe clean the mounting surface on the pipe.
Check to insure that the Tool Blocks will clear the pipe when the Clamshell is
mounted.
Close the sections of the Clamshell around the pipe, keeping the mating
surfaces clean.
Check that the Alignment Pins have seated the split-lines properly.
Bolt the sections of the Clamshell together using the Locking Screws in the
Housing and in the Headstock.
Tightening torque should be 50 ft-lbs (68 Nm) to 60 ft-lbs (81 Nm).
Loosen the Lock Blocks, rotate and refasten them to the Headstock.
Using the fully Adjustable Clamping Pads, clamp the Clamshell to the pipe as
follows.
Rough center and square the Clamshell by tightening the four (4) Clamping
Pads independently.
Check the center and square by eye.
The Adjustable Pads tend to square the Clamshell to the pipe.
If additional precision in squaring is required, consult TRI TOOL INC.
about alternate methods of squaring.
