CLEANING

Dry cleaning solvent (P-D-680), used to clean parts 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 exces-

sive heat and don't smoke when using it. Failure to do so could

cause serious injury. If you become dizzy while using cleaning

solvent, get fresh air immediately, and get medical attention. If

contact with skin or clothes is made, flush with large amounts of

water. If contact with eyes is made, wash eyes with water immed-

iately, and obtain medical aid immediately.
