Keep all parts clean from contaminants.Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components.To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly.Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination.
Note: A hydraulic oil sample should be obtained before any maintenance is performed in order to establish the system contaminant level. Refer to Fluid Analysis Laboratory Guide, SEBF3116, "Obtaining an Oil Sample for S O S Analysis". Refer to Operation and Maintenance Manual, "Sampling Interval and Location of Sampling Valve" for the correct location.
