NOTICE

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, PERJ1017, "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.


------ WARNING! ------

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.


------ WARNING! ------

Hydraulic accumulator contains gas and oil under high pressure. Improper removal or repair procedures could cause severe injury. To remove or repair, instructions in the service manual must be followed. Special equipment is required for testing and charging.


------ WARNING! ------

At operating temperature, the hydraulic tank is hot and under pressure.

Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.



NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


    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 will help to prevent fluid loss and this helps to prevent contaminants from entering the system.

  1. Release the nitrogen charge from the steering accumulator. Refer to Steering Systems Operation/Testing and Adjusting, "Steering Accumulator - Test and Charge".

  2. Drain the hydraulic oil from the steering hydraulic tank into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Steering System Oil - Change".
