CLEANING

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 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 immediately, and obtain medical aid immediately.

WARNING

Wear safety glasses when drying parts with compressed air.

Failure to do so could cause serious injury to eyes and possible
