7.5 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.
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 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.

7.6 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. Release the two latches 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.
