TRANSFORMER 2416082 - Caterpillar

Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
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.
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.
Park the machine on a smooth, level surface. Move away from other operating machines and away from personnel. Lower the work tool to the ground. Stop the engine.
Permit only one operator on the machine. Keep other personnel away from the machine or in the operator's sight.
Engage the parking brake. Place blocks in front of the wheels and behind the wheels.
When the work tool is raised for testing or for adjusting, make sure that the work tool is supported correctly. Also, make sure that the work tool is fully in the DUMP position. The lift circuit has high oil pressure when the lift arms raise the front of the machine.Note: Do not stop the machine with the front of the machine off the ground unless this is required for a test. Lower the machine to the ground and stop the engine.
Install the locking pins and bars.
Cycle the hydraulic control levers through all positions in order to release the pressure in the hydraulic system. Place the tilt control lever in the FLOAT position. Place the lift control lever in the HOLD position.
To relieve all of the pressure in the hydraulic oil tank, slowly loosen the filler cap.Note: All hydraulic pressure must be released before any hydraulic components are worked on.
Install the filler cap.During a diagnosis of the hydraulic system, remember that correct oil flow and correct pressure are necessary for correct machine operation. The pump output increases as the engine speed increases and vice versa. Oil pressure is caused by resistance to the flow of oil.
