WARNING
Dry clear-ring 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 immedi-
ately, and obtain medical aid immediately.
WARNING
Wear safety glasses when drying parts with compressed air. Fail-
ure to do so could cause serious injury to eyes and possible blind-
ness. If you hurt your eyes or if a foreign object is blown into
your eyes, seek medical attention immediately.
