WARNING

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

excessive 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 and medical

attention immediately. If contact with skin or clothes is made, flush with large amounts of

water. If contact with eyes is made, wash eyes with water and seek medical aid

immediately.
