3. Ensure a complete mating of joint before tightening the bolts
or nut.
4. Tighten the joint to the specific torque. For the nut joint, pay
special attention to following cautions.
Always use two wrenches to prevent the tubes from twist-
ing.
Pipes will rotate 15 - 20 clockwise during tightening, so
ensure final position is the correct location.
When finally tightening the pipes, do not rotate the fixed
