7.11 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
Use clean, fresh unleaded gasoline with a minimum octane
rating of 87 (90 for Scag LC2P77F and Scag LC2P82F)
and a maximum of 10% Ethanol.
Fill to the bottom of the filler neck insert (approximately
5-1/2 gallons at the beginning of each operating day. See
Figure 7-9.
DO NOT over fill. The empty space in the fuel tank allows
the fuel to expand. Overfilling the fuel tank may result in
fuel leakage, damage to the engine and/or damage to the
machine's emsissions system.
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.
Extinguish all cigarettes, cigars, pipes and other sources
of ignition.

1. Use only an approved gasoline container.
2. NEVER remove the gas cap or add fuel with the
engine running. Allow the engine to completely cool
before fueling.
3. NEVER fuel the machine indoors or in an enclosed
trailer.
4. 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.
5. 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.
6. Remove the machine from the truck or trailer and
fuel on level ground. If this is not possible, then
refuel the machine with a portable container, rather
than from a gasoline dispenser nozzle.
7. Keep the 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.
8. If fuel is spilled on clothing, change clothing
immediately and wash affected skin.
9. DO NOT start the engine until any spilled fuel has
been cleaned up or has evaporated.
10. NEVER over fill the fuel tank. Replace gas cap and
tighten the fuel cap until it ratchets.

by the engine manufacturer. Refer to Engine Operator's
Manual.
