CONTAMINATION CONTROL
Filters provide adequate control of the contamination problem during all normal hydraulic system operations. Control of the size and amount of contamination entering the system from any other source is the responsibility of the people who service and maintain the equipment. Therefore, precautions should be taken to minimize contamination during maintenance, repair, and service operations. Should the system become contaminated, the filter element should be removed and cleaned or replaced. As an aid in controlling contamination, the following maintenance and servicing procedures should be followed at all times: (1) Maintain all tools and the work area (workbenches and test equipment) in a clean, dirt-free condition. (2) A suitable container should always be provided to receive the hydraulic liquid that is spilled during component removal or disassembly procedures. (3) Before disconnecting hydraulic lines or fittings, clean the affected area with dry cleaning solvent. (4) All hydraulic lines and fittings should be capped or plugged immediately after disconnecting. (S) Before assembly of any hydraulic components, wash all parts in an approved dry cleaning solvent. (6) After cleaning the parts in the dry cleaning solution, dry the parts thoroughly and lubricate them with the recommended preservative or hydraulic liquid before assembly. Use only clean, lint-free cloths to wipe or dry the component parts. (7) All seals and gaskets should be replaced during the re-assembly procedure. Use only those seals and gaskets recommended by the manufacturer. (8) All parts should be connected with care to avoid stripping metal' slivers from threaded areas. All fittings and lines should be installed and torqued in accordance with applicable technical instructions. (9) All hydraulic servicing equipment should be kept clean and in good operating condition.
