W A R N I NG
Wear eye protection when blowing solvent from parts. Compressed air used for
cleaning purposes must not exceed 30 psi (2.1 kg/cm2). Do not direct
compressed air against the skin. Use goggles or full face shield.
Potential health hazards result from inhalation of petroleum solvent vapors and
from contact of solvent with skin. Use rubber gloves and hand cream for
protection, and work with adequate ventilation.
Dry cleaning solvent PD-680 used to clean park is potentially dangerous to
personnel and property. Avoid repeated and prolonged skin contact. Do not
use near open flame or excessive heat. Flash point of solvent is 100ºF-138ºF
(38ºC-60ºC).
Clean sling assemblies components with dry cleaning solvent and dry thoroughly.
Inspect sling lift rings for cracks or breaks and replace if damaged.
Inspect U-bolts (3) for cracks or breaks and replace if damaged.
Inspect lower leg assemblies (6) for broken strands, worn thimbles (8) and replace if damaged.
Inspect lift hooks (9) for cracks, breaks and distortions. Inspect throat opening of hooks. If opening is
more than 15 percent in excess of nominal, more than a 10 degree twist from the plane of the unbent
hook, or wear exceeds 10 percent of the original dimension, or if damaged, replace hooks.
Inspect wire rope for broken or worn outside wires, reduction of rope diameter below nominal value,
corroded, broken, or frayed wires at end connections. Check for severe kinking, crushing, cutting or
unstranding. Replace wire rope if damaged.
