SPECIFIC MAINTENANCE INSTRUCTIONS--Continued
Cleaning compound is toxic and flammable. Always wear
protective goggles and gloves and use only in a well-ventilated
area. Avoid contact with skin, eyes, and clothes and do not
breathe vapors. Do not use near open flames or excessive heat.
Cleaning is normally done by the dip-tank and/or vapor-degreaser methods, or by cleaning with
cloths soaked in cleaning compound.
CLEANING OF MATERIEL RECEIVED FROM STORAGE
Clean materiel received from storage by Direct Support maintenance units by the dip-tank, vapor-
degreaser, or steam method, whichever is applicable or available.
Cleaning compounds can burn easily, give off harmful
vapors, and are harmful to skin and clothing. When using
them, keep away from open fire and use in a well-ventilated
area to avoid possible injury or death. If cleaning compound
gets on skin or clothing, wash immediately with soap and water.
Dip-tank method. Disassemble as required and place parts in a perforated metal basket.
Submerge and agitate basket in a tank containing cleaning compound. Repeat using a
second tank with cleaning compound. Extent of treatment in each tank will depend on ease
with which parts are cleaned.
Vapor-degreaser method. Tanks containing a heated solution of perchloroethylene (Type
II) or other degreaser is used for degreasing items that are very greasy or oily and are not
readily cleaned by the dip-tank method. Place parts in a perforated metal basket and
submerge below the vapor tank. Keep basket in this position until all grease, oil, or dirt
melts and runs off the parts. If necessary, materiel may be washed with a degreasing spray
Steam method. Place parts in a perforated metal basket and steam-treat until clean. This
method is less efficient than vapor-degreaser method, and parts may require additional
cleaning to remove final traces of grease, oil, or dirt, particularly from recesses.
If some time is to elapse before the start of repair or overhaul operation, apply a coat of corrosion
preventive oil to all finished metal surfaces to prevent rusting.
CLEANING AFTER SHOP INSPECTION
Compressed air used for drying or cleaning purposes must
not exceed 30 psi (207 kPa). Wear protective clothing (goggles
and gloves) and use caution to avoid injury to personnel.
