UNIT CLEANING PROCEDURES.
•
Drycleaning solvent P-D-680 is toxic and flammable. Wear protective goggles, face mask, and gloves and
use only in a well-ventilated area. Avoid contact with skin, eyes, and clothes and don't breathe vapor. Do not
use near open flame or excessive heat. The flash point for type I drycleaning solvent is 100°F (38°C) and for
type II is 140°F (60°C). If you become dizzy while using cleaning solvent, get fresh air immediately and get
medical aid. If contact with eyes is made, flush eyes with water and get medical aid immediately.
•
DO NOT use diesel fuel, gasoline, or benzene (benzol) for cleaning.
•
DO NOT SMOKE when using cleaning solvent. NEVER USE IT NEAR AN OPEN FLAME. Be sure there is a
fire extinguisher nearby and use cleaning solvent only in well-ventilated places.
•
USE CAUTION when using cleaning solvents. Cleaning solvents evaporate quickly and can irritate exposed
skin if solvents contact skin. In cold weather, contact of exposed skin with cleaning solvents can cause
frostbite.
a.
When cleaning ball or roller bearings, place in a basket and suspend in a container of drycleaning solvent, P-
D-680 (item 21, Appendix E). If necessary, use a brush (item 2, Appendix E) to remove caked grease or chips. Avoid
rotating bearings before solid particles are removed to prevent damaging races and balls.
b.
Do not clean preformed packings or other rubber parts in drycleaning solvent. Wipe with a clean, dry, lint-free
cloth.
c.
For exterior cleaning of frame and structural components, use detergent (item 11, Appendix E) in a solution
as recommended on the container. Leave application on items surface for approximately 10 minutes before rinsing.
Rinse with hot or cold water under pressure. If available, use hot water under 80 to 120 lb (36 to 54 kg) pressure. An
ordinary garden hose may be used if no other equipment is available. If pressurized water supply is not available, wash
painted surfaces with a solution of 1/4 cup soap chips (item 3, Appendix E) to one gallon of water.
