Drycleaning 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 do not breathe vapors. Do not use near
open flame or excessive heat. The flash point is 100o-138°F (38o-50o C). If
you become dizzy while using 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.
Never use gasoline to clean parts. Gasoline is highly flammable. Serious
personal injury could result if fuel ignites during cleaning.

To prevent injury, compressed air will not exceed 30 psi (207 kPa). Use only
with effective chip guarding and personal protective equipment (goggles/shield,
gloves, etc.).
Removing Deposits. After soaking parts in solvent, wash away deposits by flushing or
spraying. Where necessary, brush with a soft-bristle brush moistened in solvent. Use
compressed air to dry all parts, except bearings. Bearings must be allowed to air dry.
Tools. Do not use abrasive wheels, or compounds in cleaning parts, unless called for in
detailed instructions. These procedures may weaken a highly stressed part.
Ball and Roller Bearings. When cleaning ball or roller bearings, place them in a basket and
suspend them in a container of drycleaning solvent. If needed, use a brush to remove bearing
before solid particles are removed to prevent damaging races and balls. When bearings have
been cleaned, coat them lightly with lubricating oil to remove solvent. Refer to TM 9-214 for
additional instructions on cleaning bearings.
Rubber Parts. Do not clean O-rings or other rubber parts in drycleaning solvent. Clean by
washing with a mild solution of soap and water. Wipe with a clean, dry, lint-free cloth.
