5-5. General cleaning instructions.
Prior to removal or disassembly of major components, clean off excess oil or dirt with a cleaning solvent or
Use a cleaning solvent to clean parts such as gears, housings and hand packed bearings.
Cleaning solvents are dangerous to your health. Long term effects from solvents such as Fed.
Spec. P-D-680 can include cancer. Short term effects, especially when used in poorly ventilated
areas, include unconsciousness and death. Some solvents, such as Methyl Ethyl Ketone Peroxide
(also used as a fiberglass catalyst) can be more hazardous to eyesight than battery acid. Limit
exposure to solvents and use eye protection. Always insure that ventilation is adequate.
Do not immerse oil impregnated bearings or sealed bearings in cleaning solvent; clean with a
solvent moistened cloth.
Use brushes to clean irregular shaped surfaces; use wooden pegs to clean ports and orifices. Use a lint
free cloth to wipe parts clean.
Exercise care when handling machined and polished surfaces to avoid nicks and other damage. Do not
immerse more than one metal machined part in solvent at same time unless such parts are separated or protected from
contacting each other.
