Operation In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40.
2. Clean around each fuel tank cap and remove the cap. Add fuel to both fuel tanks, until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows the fuel to expand. Do not fill the fuel tanks completely full. 3. Install fuel tank caps securely. Wipe up any fuel that may have spilled. 4. If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank.
5. To raise the roll bar, remove the hairpin cotter pins and remove the two pins (Figure 7). 6. Raise the roll bar to the upright position and install the two pins and secure them with the hairpin cotter pins (Figure 7). There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. Important: Always use the seat belt with the roll bar in the raised position. • Do not wear the seat belt when the roll bar is in the down position.
Think Safety First Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Figure 9 1. Always keep the roll bar in the raised and locked position and use the seat belt. 2.

Transporting Machines Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets or bystanders avoid injury. To transport the machine: • Lock the brake and block the wheels. • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.
Important: Do Not attempt to turn the unit while on the ramp; you may lose control and drive off the side. Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the unit to tip backward. Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. • Use extreme caution when operating a unit on a ramp.
Mowing Direction tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine TORO replacement blade. Alternate mowing direction to keep the grass standing straight.
