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 obtain medical aid immediately.

Compressed air must not exceed 30 psi. Wear safety glasses when

drying parts with compressed air. Failure to do so could cause serious
