Fuel System Maintenance

This Operators Manual contains more detailed fuel and fuel system maintenance information than the engine Owners Manual, which is a general-purpose reference relating to fuel and fuel maintenance.
Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality require your attention to avoid downtime and extensive engine repairs.
The fuel system has extremely tight tolerances due to the emissions and control requirements. Diesel fuel quality and cleanliness is more important for the longevity of todays high-pressure common rail (HPCR) fuel-injection system used on diesel engines.
Important  
Water or air in the fuel system will damage your engine! Do not assume that new fuel is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and use your fuel supply within 180 days.
 
Important  
If you do not follow the procedures for fuel filter replacement, fuel system maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform all fuel system maintenance at the specified intervals or whenever the fuel is contaminated or its quality is poor.
 
Fuel Storage
Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks is often overlooked and leads to the contamination of fuel delivered to the machine.
  • Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days. This helps eliminate water and other contaminates in the fuel.
  • If you do not remove the water from the storage tank or machine fuel tank, it can lead to rust or contamination in the storage tank and fuel system components. Tank sludge developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel injectors.
  • Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality in the tank.
  • Ensure that your fuel comes from a quality supplier.
  • If you find water or contaminants in your storage tank or machine fuel tank, work with your fuel provider to correct the problem and perform all fuel system maintenance.
  • Do not store diesel fuel in tanks or canisters made with zinc-plated components.
Servicing the Fuel Tank
  1. Prepare the machine for maintenance.
  2. Drain and clean the tank if the fuel system becomes contaminated or if the machine will be stored for an extended period. Use clean fuel to flush out the tank.
Inspecting the Fuel Lines and Connections

Troubleshooting
 

Diagnostic ACE Display

The machine is equipped with an electronic controller that controls most machine functions. The controller determines what function is required for various input switches (i.e., seat switch, key switch, etc.) and turns on the outputs to actuate solenoids or relays for the requested machine function.
For the electronic controller to control the machine as desired, each of the input switches, output solenoids, and relays must be connected and functioning properly.
Use the Diagnostic ACE display to help verify and correct electrical functions of the machine.

Verifying the Interlock Switch Function

  1. Park the machine on a level surface, lower the cutting units, engage the parking brake, and shut off the engine.
  2. Remove the cover from the control panel.
  3. Locate the wire harness and loop-back connector .
  4. Carefully unplug the loop-back connector from the harness connector.
  5. Graphic
    G417042
  6. Connect the Diagnostic ACE display connector to the harness connector.
    Note: Ensure that the correct overlay decal is positioned on the Diagnostic ACE display.
  7. Turn the key switch to the On position, but do not start the machine.
    Note: The red text on the overlay decal refers to input switches and the green text refers to outputs.
  8. The inputs displayedLED, on the lower right column of the Diagnostic ACE, should illuminate. If the outputs displayedLED illuminates, press the toggle button, on Diagnostic ACE, to change LED to inputs displayed.
    The Diagnostic ACE illuminates the LED associated with each of the inputs when that input switch is closed.
  9. Individually, change each of the switches from open to closed (i.e., sit on the seat, engage the traction pedal, etc.), and note that the appropriate LED on the Diagnostic ACE blinks on and off when the corresponding switch is closed. Repeat this for all switches that you can change by hand.
  10. If a switch is closed and the appropriate LED does not turn on, check all wiring and connections to the switch and/or check the switches with an ohm meter or multimeter. Replace any malfunctioning switches and repair any malfunctioning wiring.
    Note: The Diagnostic ACE is also able to detect which output solenoids or relays are turned on. This is a quick way to determine if a machine malfunction is electrical or hydraulic.

Verifying Output Function

  1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.
  2. Remove the access panel from the side of the control arm.
  3. Locate the wire harness and connectors near the controller.
  4. Carefully unplug the loop-back connector from the harness connector.
  5. Connect the Diagnostic ACE connector to the harness connector.
    Note: Make sure that the correct overlay decal is positioned on the Diagnostic ACE.
  6. Turn the key switch to the On position, but do not start the machine.
    Note: The red text on the overlay decal refers to input switches and the green text refers to outputs.
  7. The outputs displayedLED, on lower right column of Diagnostic ACE, should illuminate. If the inputs displayedLED illuminates, press the toggle button, on the Diagnostic ACE, to change the LED to outputs displayed.
    Note: It may be necessary to toggle between inputs displayedand outputs displayedseveral times to do the following step. To toggle back and forth, press the toggle button once. You may do this as often as needed. Do not hold the button.
  8. Sit on the seat and attempt to operate the desired function of the machine. The appropriate output LEDs should illuminate to indicate that the ECM is turning on that function.
    Note: If the correct output LEDs do not illuminate, verify that the required input switches are in the necessary positions to allow that function to occur. Verify correct switch function. If the output LEDs are on as specified, but the machine does not function properly, this indicates a non-electrical problem. Repair as necessary.
    Note: If each output switch is in the correct position and functioning correctly, but the output LEDs are not correctly illuminated, this indicates an ECM problem. If this occurs, contact your authorized Toro distributor for assistance.
    Important  
    The Diagnostic ACE display must not be left connected to the machine. It is not designed to withstand the environment of the everyday use of the machine. When you are finished using the Diagnostic ACE, disconnect it from the machine and connect the loop-back connector to the harness connector. The machine does not operate without the loop-back connector installed on the harness. Store the Diagnostic ACE in a dry, secure location in the shop, not on the machine.
