a. Performance Check

(1) Rotate knurled rim of indicator dial on TI until pointer indicates the cable

diameter being used.

(2) Rotate cable size-gage on TI ccw against the stop pin.

(3) Increase tension on cable by adding weights from balance weight sets or

standard weight set (A1, A2, or A4) to hanger assembly until total weight (tare weight plus

added weight) equals 25 pounds.

(4) Apply TI to cable (B1) by compressing actuating handle and making certain that

cable is aligned in the jaws and against jaw base (fig. 1).

(5) Slowly release compression until riser block and sectors (fig. 1) are firmly

gripping cable. Release compression entirely.
