Sudden movement of the machine or release of air or oil under pressure can cause possible injury or death to persons on or near the machine. To prevent possible injury or death, do the procedure that follows before testing and adjusting the Hydraulic System. |
 |
- Move the machine to a smooth horizontal location. Move away from any machines that are working and any personnel.
- Move the shift control lever to the NEUTRAL position. Activate the parking brakes.
- Lower the body to the frame.
- Stop the engine. Move the engine start switch to the OFF position.
Note: The pressure will not be released from the steering accumulators when you use the battery disconnect switch or the engine shutdown switch.
- While the engine is not running, turn the steering wheel completely in both directions. Continue to turn the steering wheel in both directions until the front wheels will not move.
- Turn the engine start switch key to the ON position. Do not start the engine. Turn the engine start switch key to the OFF position.
Note: This process releases any pressure that is in the solenoid valve which is used to purge the accumulator. Refer to Operation and Maintenance Manual, "Steering Accumulator Pressure - Release" for more information.
- Ensure that all of the oil pressure is released before any fittings, hoses, or components are worked on.
- Permit only one operator on the machine. Either keep other personnel away from the machine, or keep other personnel in the view of the operator.
- Place blocks in front of the wheels and behind the wheels.
