NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. 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 in Caterpillar machines. 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 pressure in the implement hydraulic circuits which include the boom, the stick and the bucket before any of the hydraulic lines or any of the components are disconnected or removed. Release the pressure as follows:
1. Shut off the engine and place key in the ON position. Put the hydraulic activation control lever in the UNLOCK position.
1. Move the control levers for the boom, the stick and the swing to all full stroke positions. This will release any pressure that might be present in the pilot system.
1. Return the key to OFF position.
1. Slowly loosen the fill plug on the hydraulic tank, and release the pressure.
1. Tighten the fill plug on the hydraulic tank.
1. The pressure in the hydraulic system has been released, the lines and the components can be removed.
