Some obvious signs of cable damage are as follows:
1. Exposed inner wire, stretching or cuts in the coating, or broken
coating in the area that passes over a pulley
2. A zigzag or wavy pattern
3. Kinks, which may indicate internal damage

In addition to inspecting the cables and end connections for damage,
check the following:
• Ensure that each cable is properly adjusted and tightened at the top
of the weight stack.
• Check cable pulleys, end connections, and end fittings. Make sure
all connections are tight, adjusting cable tension as necessary.
• Make sure that the cable bolt is threaded at lease seven turns into
the selector stem or a minimum of ¹₂-inch (13 mm). The distance
shown should be ³₄-inch (19 mm) or less. Tighten the locking jam
nut to 600 in-lb (68 N-m). Refer to Figure 2.
