Compressed air used for cleaning and drying purposes can create airborne particles
that may enter the eyes. Pressure shall not exceed 30 psig and use only with adequate
chip guards and chipping goggles. Failure to observe this warning could result in
servere personal injury or death.
Clean all non-electrical metal parts in dry cleaning solvent (Federal Specification P-D-680) and dry
with filtered compressed air.
Clean electrical components with filtered compressed air and a soft bristle brush.
Visually inspect cover connector bracket and base for cracks, corrosion, dents, and other damage.
Inspect load resistor for cracks, corrosion, burns, and evidence of overheating.
Inspect diodes for burns and other damage.
Inspect electrical connector for bent or broken pins, burns, cracks, and other damage.
Check all wiring for burned insulation, bare wires, broken or loose connections and other damage.
If the wiring harness has sustained damage and requires repair or rebuild, refer to figure 3-65 for
