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.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
At operating temperature the implement hydraulic oil tank is hot and under pressure. Hot oil can cause burns.To prevent possible injury, release the pressure in the implement hydraulic system before hydraulic lines or components are disconnected or removed.
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, SEBU7439, "Sampling Interval and Location of Sampling Valve" for the correct location.
