7.5 Engine Fuel System

DANGER

To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

A. Filling the Fuel Tank

Fill the fuel tank at the beginning of each operating day to within one (1) inch below the bottom of the filler neck. Do not overfill. Use clean, fresh unleaded gasoline with a minimum octane rating of 87 and a maximum of 10% Ethanol.

DO NOT use E85 Fuel. Using E85 Fuel will cause severe damage to the engine.

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

2.Use only an approved gasoline container.

3.Never remove the gas cap or add fuel with the engine running. Allow the engine to completely cool before fueling.

4.Never fuel the machine indoors or in an enclosed trailer.

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

6.Never 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.

7.Remove the machine from the truck or trailer and fuel on the ground. If this is not possible, then refuel the machine with a portable container, rather than from a gasoline dispenser nozzle.

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

9.If fuel is spilled on clothing, change clothing immediately and wash affected skin.

10.Replace gas cap and tighten securely.

B. Replacing In-Line Fuel Filter Elements

The engine fuel filter should be replaced after every 500 hours of operation or annually, whichever occurs first.

1.Close the shut-off valve.

2.Remove and replace the engine fuel filter. Open the fuel shut-off valve.
