Sudden movement of the machine or release of oil under pressure can cause injury to persons on or near the machine.To prevent possible injury, perform the procedure that follows before testing and adjusting the hydraulic system.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
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.
Before any tests are performed, visually inspect the complete hydraulic system for oil leaks and for damaged parts. Refer to Testing and Adjusting, "Visual Inspection" for further information on visual inspection.When any test is made to the hydraulic system, the hydraulic oil must be at normal temperature for operation. In order to increase the oil temperature, start the engine. Raise and lower the work tool. Extend and retract the boom several times.Note: Permit only one operator on the machine. Keep other personnel away from the machine or in the operator's sight.
Move the machine to a smooth horizontal location that is away from other machines and from personnel.
Lower the work tool to the ground. Stop the engine.
Chock the rear wheels and engage the parking brake.
Ensure that all of the pressure is released from the hydraulic system before adjustments are made.Before you troubleshoot a problem, perform a visual inspection of the machine. If visual checks fail to identify a problem, refer to Testing and Adjusting, "Hydraulic System Troubleshooting". This section of the module lists the possible causes of a known problem. In most cases, there will be more than one possible cause listed. Individual checks and tests may be necessary in order to identify the actual cause.
