TM 9-2320-364-34-1

Do not use soap or alkalies for cleaning tank interiors.

k. Oil and Fuel Tanks. Pay special attention to all warnings and cautions when working on truck's fuel tank. Oil

tanks and fuel tanks should be flushed, using a spray gun and drycleaning solvent.

l. Battery. Exterior surfaces of the electrical system and battery should be cleaned with a weak solution of baking

soda and water. Apply solution with a bristle brush to remove corrosion. Pay special attention to all warnings and

cautions when working on batteries.

Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face

shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and

clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when

using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees

C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may

result in injury or death to personnel.

If personnel become dizzy while using cleaning solvent, immediately get fresh air and

medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts

eyes, immediately flush eyes with water and get immediate medical attention.

Never use gasoline or other petroleum base products to clean or preserve hydraulic system parts.

m. Hydraulic System. When cleaning hydraulic system parts use drycleaning solvent, P-D-680. Clean and dry

parts thoroughly to make sure no residue remains. If a coating preservative is required before assembly, apply a light

film of preservative oil. If petroleum-free solvents are not available, use the same hydraulic fluid as used in the truck's

system.
