    Adding Fuel

    Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

    Fuel tank capacity: 41 L (10.8 US gallons)

    Use summer-grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter-grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Using winter-grade fuel at lower temperatures provides lower flash point and cold flow characteristics which will ease starting and reduce fuel filter plugging.

    Using summer-grade fuel above -7°C (20°F) will contribute toward longer fuel pump life and increased power compared to winter-grade fuel.

    Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine.

    Biodiesel Ready

    This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

    • The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

    • The blended fuel composition should meet ASTM D975 or EN590.

    • If you spill biodiesel fuel blends, the fuel may damage painted surfaces.

    • Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

    • Monitor the seals, hoses, and gaskets in contact with fuel as they may degrade over time.

    • Expect fuel filter plugging for a time after converting to biodiesel blends.

    • Contact your authorized Toro distributor if you want more information on biodiesel.

    Filling the Fuel Tank

    Note: If possible, fill the fuel tank after each use; this minimizes possible buildup of condensation inside the fuel tank.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering, or stability is in question.

    • Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.

    • Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

    • Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.

    • Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.

    • If possible, keep the cutting unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.

    • Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.

    Operating Tips

    • Practice driving before operating the machine, because it has a hydrostatic transmission and its characteristics are different than some turf-maintenance machines.

    • To maintain enough power for the machine and deck while mowing, regulate the traction pedal to keep the engine speed (rpm) high and constant. Decrease the ground speed as the load on the cutting blades increases; increase the ground speed as the load on the blades decreases. This allows the engine, working with the transmission, to sense the proper ground speed while maintaining a high blade-tip speed necessary for good quality of cut. Therefore, allow the traction pedal to move upward as the engine speed decreases, and press pedal slowly as the speed increases. When driving from 1 work area to another (with no load and the deck raised), have throttle in the FAST position and press the traction pedal slowly but fully to attain the maximum ground speed.

    • Before shutting off the engine, move all controls to the NEUTRAL position and move the throttle to the SLOW position. Rotate the key switch to the OFF position to shut off the engine.

    • The engine does not run when the engine coolant is in over-temperature condition. Let the engine and cooling system cool, and check the cooling system; refer to Checking the Cooling System and Coolant Level.

    • It is important to carry socket wrench with a 100 mm extension and 17 mm socket while operating the machine. Use the socket wrench to open the bypass valve if you need to push or tow the machine.

    After Operation

    General Safety

    • Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position, Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.

    • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended.

    • Allow the engine to cool before storing the machine in any enclosure.

    • Remove the key and shut off the fuel (if equipped) before storing or hauling the machine.

    • Never store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.

    • Maintain and clean the seat belt(s) as necessary

    Storage

    Storage Safety

    • Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or other appliance.

    Storing the Battery

    • Service the battery and cables as follows:

      1. Remove the battery terminals from the battery posts; refer to Removing the Battery.

      2. Clean the battery, terminals, and posts with a wire brush and baking-soda solution.

      3. Coat the cable terminals and battery posts with Grafo 112X skin-over grease (Toro Part No. 505-47) or petroleum jelly to prevent corrosion.

      4. If you plan to store the machine more than 30 days, remove the battery and charge it fully.

        Note: Slowly charge the battery for 24 hours every 60 days to prevent lead sulfation of the battery.

    • Store the battery in position on the machine.

    • Leave the cables disconnected if the battery is stored in the machine.

    • Store the battery in a cool atmosphere to avoid quick deterioration of the charge in the battery.

    • To prevent the battery from freezing, ensure that it is fully charged. The specific gravity of the electrolyte in a fully charged battery is between 1.265 to 1.299.

    5. Lubricate all grease fittings and apply oil to pivot points and the transmission bypass-valve pins. Wipe clean any excess lubricant.

    6. Lightly sand and use touch-up paint on scratched or chipped paint, or rust. Repair any dents in the metal body.

    Preparing the Engine

    1. Change the engine oil and oil filter; refer to Changing the Engine Oil and Filter.

    2. Start the engine and run it at idle speed for 2 minutes.

    3. Shut off the engine.

    4. Empty the fuel from the fuel tank, fuel lines, pump, filter, and separator.

    5. Flush the fuel tank with clean diesel fuel and connect all fuel lines.

    6. Thoroughly clean and service the air-cleaner assembly; refer to Servicing the Air-Cleaner Filters.

    7. Seal the air-cleaner inlet and the exhaust outlet with weatherproof masking tape.

    8. Secure all fuel-system fittings.

    9. Check the anti-freeze protection level of the cooling system and adjust the concentration of the coolant as needed for the coldest expected temperature in your area.

    10. Check the oil-filler cap and fuel-tank cap to ensure that they are secure.
