  • Become familiar with the safe operation of the equipment, operator controls, and safety decals.

  • Always engage the parking brake (if equipped), shut off the engine, remove the key, wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing the machine.

  • Know how to stop the machine and shut off the engine quickly.

  • Check that the operator's presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.

  • Locate the pinch-point areas marked on the machine and attachments; keep your hands and feet away from these areas.

  • Before operating the machine with an attachment, ensure that the attachment is properly installed and that it is a genuine Toro attachment. Read all the attachment manuals.

  • Evaluate the terrain to determine what accessories and attachments you need to properly and safely perform the job.

  • Have the property or work area marked for buried lines and other objects, and do not dig in marked areas; note the location of unmarked objects and structures, such as underground storage tanks, wells, and septic systems.

  • Inspect the area where you will use the equipment and remove all debris.

  • Ensure that the area is clear of bystanders before operating the machine. Stop the machine if anyone enters the area.

Fuel Safety

  • Use extreme care when handling fuel. It is flammable and its vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • 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.

  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

  • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling.

  • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.

  • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

Adding Fuel

Recommended 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 you can use within 180 days to ensure fuel freshness.

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 eases starting and reduces fuel filter plugging.

Using summer-grade fuel above -7°C (20°F) contributes 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.

  • Painted surfaces may be damaged by biodiesel blends.

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

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

  • Fuel filter plugging may occur for a time after converting to biodiesel blends.

  • Contact your distributor for more information on biodiesel.

Filling the Fuel Tank(s)

  1. Park the machine on a level surface, engage the parking brake (if equipped), and lower the loader arms.

  2. Shut off the engine, remove the key, and allow the engine to cool.

  3. Clean around the fuel-tank cap and remove it (Figure 15).

    g004231
  4. Fill the tank to about 2.5 cm (1 inch) below the top of the tank, not the filler neck, with fuel.

    Important: This space in the tank allows fuel to expand. Do not fill the fuel tank completely full.

  5. Install the fuel-tank cap securely, turning it until it clicks.

  6. Wipe up any spilled fuel.

Performing Daily Maintenance

Before starting the machine each day, perform the Each Use/Daily procedures listed in the .

Important: Check the hydraulic-fluid level and bleed the fuel system before starting the engine for the first time; refer to Checking the Hydraulic-Fluid Level and Bleeding the Fuel System.
