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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Personal injury can result from the sudden release of high pressure oil.Be sure the engine has been shut off for a minimum of five minutes to ensure that the accumulator pressure is zero.The accumulator is filled with dry nitrogen. Do not loosen or remove the valve or the cap from the top of the accumulator.
Personal injury can result from hot oil or hot components.At operating temperature, oil is hot and under pressure. Hot oil can cause burns.Remove the fill cap only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand.Do not allow hot oil or components to contact skin.
Note: Put identification marks on all hose assemblies and on all tube assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.Note:
