Section 7
7.4 ENGINE FUEL SYSTEM
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 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.
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.
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 the 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.
7.5 ENGINE AIR CLEANER
A. Cleaning and/or Replacing Air Cleaner
Element
For any air cleaner, the operating environment dictates the
air cleaner service periods. Inspect and clean the air
cleaner element after every 100 hours of operation or bi-
weekly, whichever occurs first and replace the element if
required.
In extremely dusty conditions it may be necessary to
check the element once or twice daily to prevent
engine damage.
1. Loosen the two bolts securing the air cleaner cover to
the air cleaner assembly and remove the cover. Set
aside.
2
Remove the air cleaner and inspect.
3. Clean or replace the air cleaner and foam pre-
cleaner as recommended by the engine
manufacturer.
