Finally, tension the cable circuit by adding a pre-tension slightly less than ½ the 1

stage cable’s breaking strength. This is accomplished by: applying 0.68 N-m [96 oz-in]

to the lubricated pre-tensioning set screw using the torque driver provided with your

system,

slowly

moving the joint through its full range of motion, applying the specified

torque again to remove the new cable slack, and repeating this process until moving the

joint no longer reduces the tension in the cables (

i.e.

the full pre-tension has been

propagated throughout the cable circuit).
