Figure 25 Figure 26 1. Rear tie down 1. Diagnostic light Understanding the Diagnostic Light Diagnostic Ace Display The machine is equipped with an electronic controller which 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.
Verifying the Interlock Switch Function If the “outputs displayed” LED is illuminated, press the toggle button, on Diagnostic ACE, to change LED to “inputs displayed”. 1. Park the machine on a level surface, lower the cutting decks, stop the engine, and engage the parking brake. 2. Remove the access panel from the side of the control arm. 3. Locate the wire harness and connectors near the controller (Figure 27).
Mowing 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. Start the engine and move the throttle to the Fast position.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.

Engine Maintenance Servicing the Air Cleaner Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps. Service the air cleaner filter only when the service indicator (Figure 38) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed. Important: Be sure the cover is seated correctly and seals with the air cleaner body. 1.
3. Remove the oil filter (Figure 41). 3. Hold the injection pump lever arm against the high idle stop (Figure 42). 4. While pulling the throttle cable, to remove any slack, tighten the throttle cable connector. Note: When tightened, the cable pivot must be free to swivel on the injection pump lever arm. 5. If the throttle does not stay in position during operation, increase the torque on the locknut, used to set the friction device on the throttle lever. Figure 41 1. Oil filter 4.
Fuel System Maintenance DANGER Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills. Figure 43 1. Water separator filter canister • Do not fill the fuel tank completely full.
Electrical System Maintenance Important: Before welding on the machine, disconnect both cables from the battery, both wire harness plugs from the electronic control module, and the terminal connector from the alternator to prevent damage to the electrical system.
