INSPECTION
WARNING
Degreasing solvent MIL-PRF-680, Type III, used to clean parts, is potentially dangerous to
personnel and property. Eye protection is required. Avoid repeated and prolonged skin
contact by wearing rubber gloves or nonporous gloves when handling solvents or material
wet with dry cleaning solvent. Wash hands immediately after exposure with soap and water
and use a lanolin based skin cream to prevent skin drying. Do not use near open flame or
excessive heat. Be sure there is good ventilation or the solvent vapors will build up in the air
and become a poisonous mixture which can cause physical injury or even death.
1.
Clean all components removed using a wiping rag moistened with dry cleaning solvent. Dry with a clean, dry wiping
rag.
2.
Inspect all parts for damage. Look for damaged threads, broken, worn, scored, or deformed parts, cracks or corrosion.
3.
Replace damaged or defective components.
