INSPECTION
WARNING
Compressed air used for cleaning/drying can create airborne particles that can
injure the eyes. Always wear eye protection. Pressure must not exceed 30 psi
(207 kPa) or injury to personnel may result.
Dry cleaning solvent (P-D-680, Type III) is used to clean parts and is potentially
dangerous to personnel and property. Extinguish all smoking materials and do not
allow sparks or open flames near the work area. Use skin and eye protection and
work in a well-ventilated area. Flash point of dry cleaning solvent is 200F (93C).

Clean hydraulic tank and all other components with dry cleaning solvent, wiping rags, and compressed air.
2.
Inspect all components for nicks, burrs, corrosion, stripped threads, broken castings, and pitting.
Clean all
polished surfaces using crocus cloth. If parts are defective, replace as required.
