4-9 GENERAL MAINTENANCE PROCEDURES - Continued
4-9.2 General Cleaning Instructions.
Do not use scrapers, wire brushes, abrasive wheels, or compounds when cleaning parts unless
called for in detailed instructions. These procedures may alter size of machined surface and may
weaken a stressed part.
Dry Cleaning Solvent
Dry cleaning solvent P-D-680 (safety or Stoddard's solvent) is potentially dangerous. Avoid
repeated and prolonged breathing of vapors and skin contact with the liquid. Do not use near
open flame, arcing equipment or other ignition sources. Always wear eye protection and
protective clothing. The flash point of P-D-680 is 100 to 138 deg. F (30 to 59 deg. C).
Whenever dry cleaning solvent is recommended for cleaning, use item 10, Appendix E.
Mineral spirits are toxic to skin, eyes, and lungs. Skin and eye protection is required. Avoid
prolonged or repeated contact. Good, general ventilation is normally adequate.
Gasoline, Diesel Fuel
Never use gasoline or diesel fuel to clean parts.
All freons are asphyxiants and are toxic to skin and eyes. Skin and eye protection is required.
Use only in a well ventilated area.
Freons are used to clean any parts that normally come in direct contact with hydraulic fluid.
