Fatigue pits (as opposed to minor machine marks or scratches).
(3)
Cracks or serious discoloration.
b.
Check all hose surfaces for broken or frayed fabric and breaks caused by sharp kinks or chafing against other
parts of the unit. Inspect metal tubing lines for kinks. Inspect fitting threads for damage. Replace any defective parts.
Check for leaks after assembly and during initial operation period.
c.
Visually inspect all castings and weldments for cracks.
d.
Inspect all wiring for chafed or burned insulation. Inspect all connectors for loose connections and broken parts.
