Chase threaded hole using appropriate size tap.
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 ignition
sources. Always wear eye protection and protective
clothing. The 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 (2.06 bar) or less. When working with compressed
air always use chip guards, eye protection, and other
personal protective equipment.
