EXTENSION GP-FAN 2434297 - Caterpillar

Do not use an auxiliary override with this work tool. The work tool can be fully powered even if the arm bar is raised and the operator has exited the cab.Severe injury or death could occur.Do not exit the cab until the work tool and the host machine have been shutdown and the parking brake is engaged.
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.
Park the host 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 host machine. Keep other personnel away from the host machine or in the operator's sight.
Engage the parking brake. Place chocks in front of the tracks or wheels and behind the tracks or wheels.
When the work tool is raised for testing or for adjusting, make sure that the work tool is supported correctly. The lift circuit has high oil pressure when the lift arms raise the work tool.Note: Do not stop the host machine with the work tool off the ground. Lower the work tool to the ground and stop the engine.Note: All hydraulic pressure must be released before you make any adjustments or any repairs to the hydraulic system. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release".During a diagnosis of the hydraulic system, remember that correct oil flow and correct pressure are necessary for proper 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.
