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 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.

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