SERVICING:
Dry cleaning solvent P-D-680 (safety or Stoddard’s Solvent)
is potentially dangerous. Avoid repeated and prolonged
breathing of vapors and skin contact with the liquid. Do
not use near open flame, arcing equipment, or other igni-
tion sources. Always wear eye protection and protective
clothing. Flash point of P-D-680 is 100° to 138° F (38° to
59° C).
Death or serious injury could occur if compressed air is
directed against the skin.
Do not use compressed air for
cleaning or drying unless the pressure is/has been reduced to
30 psi (207 kPa) or less. When working with compressed
air always use chip guards, eye protection, and other per-
sonal protective equipment.
Remove grease, oil, and fuel deposits by wiping with rags dampened with P-D-680 dry cleaning
solvent. Remove excess dry cleaning solvent and dry with compressed air.
