A. FILLING THE FUEL TANK
Fill to the bottom of the filler neck insert (approximately
12 gallons indicating Full (F) on the fuel gauge) at the
beginning of each operating day. See Figure 7-6. 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 proper ty 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.
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 the fuel cap until it
ratchets.
B. FILLING THE FUEL TANK
Fill the fuel tank at the beginning of each operating day to
within one inch below the filler neck. Do not overfill. Use

40.
