Move the machine to a smooth, horizontal location that is away from operating machines and away from personnel.
Permit only one operator on the machine. Keep all other personnel away from the machine or in the operators sight.
Place the steering control lever in the NEUTRAL position.
Engage the parking brake.
Lower the attachments to the ground.
Stop the engine.
Turn the key to the ON position, but do not start the engine.
Verify that the implement shutoff control is in the UNLOCKED position.
Move the implement control levers and the transmission control lever through the full range of travel several times. This will relieve any pressure that may be present in the implement hydraulic system and the power train system.
Loosen the filler cap on the hydraulic tank so that the pressure in the tank is released. The machine may be equipped with a breaker valve. The breaker valve will be located on top of the tank. To release the pressure in the tank, press the button on top of the breaker valve.
Tighten the filler cap on the hydraulic tank.
Make sure that the pressure in the entire hydraulic system has been released.Reference: For additional guidance with preparing the machine for testing, refer to the Testing and Adjusting manual or the Troubleshooting manual for your machine.Note: The monitoring system (if equipped) for your machine accesses many values that are useful in troubleshooting the hydraulic system. When the situation is appropriate, use the monitoring system in order to find a pressure or determine a system problem.
