8.
Tighten the jam nut toward the head plate assembly and frame anchor.
9.
Torque the jam nuts to 20-25 FT-LBS. (27.2 - 34.0 Nm).
Tensioning Cable
Cable should have enough tension so it stays seated into the pulley but not so tight that it pulls the head plate off the
weight plate below it.
1.
If the head plate has lifted, loosen the jam nuts at the terminations and loosen the threaded plugs a half turn until
the head plate comes to rest on the weight plate below. Check that the threaded plugs are engaged at least 1/2”
(12.7mm) at each termination.

Strength Cable Wear Guide
Replace cable at first sign of any of the following:
FRACTURES:
Casing can crack or fracture under strains during use. Any
crack in the casing merits cable replacement even if no
wire rope is exposed.
Be especially observant for fractures near the
components on the cable assembly - IE. Nylon Ball, Nico
Loop, Threaded Plug, etc.
TWISTING/BINDING:
Inspect casing to ensure wire rope is not twisting within
its casing. Any sign of the cable twisting should be
replaced immediately.
