FLUID SPILLAGE CONTAINMENTCare 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 "Tools and Shop Products Guide, NENG2500", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose fluids according to local regulations and mandates.
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. Remove the filler cap on the hydraulic oil tank only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Be sure all the hydraulic pressure is released before any fittings, hoses or components are loosened, tightened, removed or adjusted.
Release the pressure in the hydraulic system as follows:a. Shut off the engine.b. Move the control levers through their full travel strokes. This will relieve any pressure that may be present in the pilot system.c. Slowly loosen the air breather cap on the hydraulic oil tank to release the pressure.d. Tighten the air breather cap on the hydraulic oil tank.e. The pressure in the hydraulic system has now been released. Lines and components can now be removed. Drain all fluids in a suitable container for storage or disposal.1. Drain the oil from the hydraulic system. The capacity of the hydraulic system is 190 liters (50 U.S. gal). 2.
