Do not use mineral spirits or paint thinner to clean the howitzer. Mineral spirits and
paint thinners are highly toxic and combustible. Prolonged breathing can cause
dizziness, nausea, and even death.
d. Clean the vehicle as follows:
WARNING
Dry-cleaning solvent (P-D-680) is toxic and flammable. Wear protective goggles and
gloves and use only in a well-ventilated area. Avoid contact with skin, eyes, and
clothes, and don’t breathe vapors. Do not use near open flame or excessive heat. The
flashpoint for type #1 is 100°F (38°C), and for type #2 is 138°F (59°C). If you become
dizzy while using dry-cleaning solvent, get fresh air immediately and get medical aid.
If contact with eyes is made, wash your eyes with water and get medical aid
immediately.
Remove any rust-preventive compound from exterior surfaces with dry-cleaning solvent (item 33, Appx D).
Whenever possible, the vehicle crew will help in the cleaning.
Armament parts are coated with rust-preventive compound when received from storage. Clean these parts
thoroughly with rags or a brush saturated with dycleaning solvent. After complete removal of the rust-
preventive compound, lubricate as specified in TM 9-2350-311-10 and TM 9-2350-311-20-2. Component parts
of each item should be cleaned separately where possible. Some component parts are interchangeable;
however, the parts originally assembled work best together.
