Personal injury or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.
Hydraulic oil pressure can remain in the hydraulic system on this machine after the engine and pump have been stopped. Serious injury can result if this pressure is not released before any service is done on the hydraulic systems. In order to prevent possible injury, release the hydraulic system pressure before working on any fitting, hose, or hydraulic component.Lower all attachments to the ground before service is started. If the hydraulic system must be serviced, tested, or adjusted with the attachment in the raised position, the attachments and lift cylinders must be supported properly.Always move the machine to a location away from the travel of other machines. Be sure that other personnel are not near the machine when the engine is running and tests or adjustments are being made.
Note: The pressure in the hydraulic system must be released before hose assemblies or components can be removed or disconnected.
Ensure that the machine is on a smooth, horizontal surface. Ensure that the machine is away from working machines and personnel. Lower all implements to the ground. Install the wheel lean pin in the front axle. Install the articulation lock pin. Note: Permit only one operator on the machine. Keep all other personnel away from the machine or in the view of the operator.
Activate the parking brake. Place all implements on the ground and put the blade in the FLOAT position.
If equipped, place the blade cushion in the ON position. Place the lift cylinders in the FLOAT position. The oil will return to the hydraulic tank. This will relieve pressure in the circuit.
Stop the engine.
Never remove the fill/vent plug from the hydraulic tank if the oil is hot.Air can enter the system and cause pump damage.
Carefully loosen the filler cap on the hydraulic tank in order to release the pressure in the tank.
