WARNING

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 deg. F (38 to 59 deg. 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 (2.11

kg/cm2) or less. When working with compressed air, always use

chip guards, eye protection, and other personal protective

equipment.

(g) Using dry cleaning solvent (Item 3, Appendix E), wash all parts thoroughly and blow dry using

compressed air.

(h) Inspect rotor (15) and vanes (16). Replace both along with ring (11) (repair kit) if excessive play is
