Clean all painted surfaces by spraying with hot water and detergent solution per Federal Specification P-D-
220. Parts that will be repainted may be cleaned with steam. After cleaning, refinish affected painted areas
Do not use steam or water to clean any electrical components or assemblies such as electrical gauges,
switches and solenoids.
Clean electrical components with trichloroethane, per Federal Specification O-T-620 or equivalent.
Proper precaution must be exercised to protect personnel. Stand clear of all tubing openings. After
cleaning, drain tubes, and dry with low pressure compressed air (30 psig maximum (206 KPa).
Clean outside and inside surfaces of the steel tubing and hose assemblies with compressed air, pressurized
hot water and detergent or steam.
Inspection. In general, inspect as follows:
Inspect for visible wear, damage, distortion, cracks, breaks, and corrosion Replace all o-rings, gaskets and
Inspect threaded parts and hardware for stripped threads, cross-threading and for nicks and burrs.

connecting nuts, and similar defects.
Inspect painted surfaces for chipping, peeling or discolored paint.
Repair or Replacement. For the most part, repair of this equipment will be made by replacement of worn or
damaged parts. Detailed repair and replacement procedures for specific parts are found in the following
Minor nicks, scoring or scratches on non-critical surfaces may be smoothed with crocus cloth per Federal
Repair or replace steel tube assemblies attachment fittings, proceed as follows:
Before attempting to repair tube fittings. Make certain stainless steel tubing is of sufficient length to fit after cutting
off end containing damaged fittings. If not long enough, replace whole tube assembly.
Cut off tubing just beyond damaged fitting
Slide tubing nut and then the sleeve onto the tubing, refer to Figure 6-1. make sure that end of tubing is free of any
burrs and is reasonably square.
Insert the end of the tubing into mating fitting, see Figure 6-2. Make certain that tubing end Is bottomed on fitting
shoulder. Apply a good grade of lubricant on end of tubing.
