Exmark 920 Operating Instructions, Biodiesel Ready, Raise the Rollover Protection System Rops

Operation

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

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the fuel to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank.

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 meets 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 blend in cold weather.

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

•Fuel filter plugging maybe expected for a time after converting to biodiesel blends.

•Contact your distributor if you wish for more information on biodiesel.
