Body. Use a spray gun and solvent mixture for cleaning exterior of body. Allow mixture to
remain on item surface for 10 minutes before rinsing. Rinse with hot water under 80 to 120 psi
(550 to 830 kPa), if available. An ordinary garden hose with nozzle may be used if other
equipment is not available. Rinse thoroughly.
CAUTION
To prevent corrosion, parts should be dipped in rust preventive within two hours of
degreasing. Failure to comply may result in damage to equipment.
Degreasing Machine. A degreasing machine may be used to remove heavy grease and oil
from metal parts.

Dry Cleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective
goggles and gloves; use only in well-ventilated area; avoid contact with skin,

Never smoke when using Dry Cleaning Solvent; the flashpoint for Type I Dry
Cleaning Solvent is 100 F (38 C) and for Type II is 138 F (50 C). Failure to
comply may result in serious injury or death to personnel.
