Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.

Always use a board or cardboard when checking for a leak.

The operational checks can be used to find leakage in the system and components that are not functioning correctly. The operational checks can be used to determine whether the pumps are functioning properly. When you perform the operational checks, check for the following conditions:

Abnormal noises in the transmission
Abnormal noises in the pumps
Abnormal engagement in the clutches through all SPEEDS

After you have completed the operational checks, inspect the power train for any leaking components, damaged components or worn components.

Start the engine and allow the transmission oil temperature to reach the normal operating temperature.
Operate the machine in the FORWARD direction and in the REVERSE direction while the machine is in the AUTOSHIFT mode. Operate the machine in all speeds for both directions. Ensure that the machine operates in both directions and all speeds.
Operate the machine in all speeds while the machine is in the MANUAL mode. Use the transmission direction and speed control lever in order to operate the machine in all speeds. Operate the machine in both the FORWARD and the REVERSE directions. Ensure that the machine operates in both directions and all speeds.
Place the transmission neutralizer override switch in the ON. Operate the machine in the FORWARD direction and apply the service brakes. Ensure that the transmission neutralizes when the brake system pressure reaches the neutralization setpoint.
Note: ET can be used to view the status of the transmission neutralizer and the programmable parameters of the transmission neutralizer can be changed by using ET.
Stop the machine. Stop the engine. Inspect the power train components for any damaged parts or leakage.
