Machine Preparation
Move the machine to a smooth horizontal location.
Use suitable lifting devices in order to lift the machine. The tracks must be able to turn freely in both directions.
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 lockout switch is in the UNLOCKED position.
Move the control levers through the full range of travel several times. This will relieve any pressure that may be present in the implement hydraulic system.
Make sure that the pressure in the entire hydraulic system has been released.
Turn the key to the OFF position.
Observe the state of the amber hazardous voltage present lamp. If the lamp is illuminated, do not perform any type of service on the machine. Wait until the lamp is not illuminated. Then, perform the lamp test in the next step.
While you observe the lamp, turn the disconnect switch to the OFF position. Then turn the disconnect switch to the ON position.Note: When the disconnect switch is cycled, the amber hazardous voltage present lamp will illuminate briefly. Then, the lamp will turn off. This indicates that the operation of the lamp is correct.
If an error message for the lamp circuit is displayed, or if the operation of the hazardous voltage present lamp does not appear to be correct, refer to the Troubleshooting, "General Information" section of the manual for information on troubleshooting the lamp circuit.
Once the hazardous voltage level has been verified to be below 50.0 VDC, the machine can be serviced. Proceed to the next step.
Locate the test port for the inlet pressure for the propulsion unit (L1). The test port is located on the left side of the tractor behind the access door.Note: Tread plate (1) can be removed in order to improve access to some test ports.

Start the engine. Warm the power train oil to 80° 10°C (176° 18°F).
Operate the engine at LOW IDLE.
Make sure that the parking brake is in the ON position.
