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. |
 |
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release" in this manual.
- Clean the outside of the swivel joint and the area around the swivel joint prior to removal.
- Oil will drain from all hose assemblies that are connected to the swivel joint. Place suitable containers under the machine in the area of the swivel joint in order to collect the oil.

Start By:
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release" in this manual.
Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for installation purposes.
| NOTICE |

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. |
