Fuel System
Use only proper types and grades of diesel fuel
(See “Fluid Capacities/Lubricants” on
page 31). Diesel fuel is flammable. Keep the machine away from
open flames. Do not smoke when refueling or when working on the
engine. Stop the engine before fueling. Failure to follow instructions
can cause fire and result in injury or death.
Important: The fuel tank is filled at the factory with United States off-road grade
diesel fuel, which is dyed red for identification. It may take several fillings of the
fuel tank before the red dye is purged from the fuel system.
Adding Fuel
1. Perform the “Mandatory Safety Shut-
down Procedure” on page 10.
2. Remove fuel cap (M, Fig. 82).
3. Inspect the wire-mesh fuel strainer
located in the filler neck and remove
any accumulated residue that may be
present. Replace the strainer if dam-
aged.
4. Add fuel into fuel filler neck (N).
Important: The engine requires low
sulfur or ultra-low sulfur diesel fuel (below 500 PPM recommended). BioDiesel
mixtures of up to a 5% (B5) are acceptable. Ultra-Low Sulfur Diesel (ULSD) fuel
lubricity must have a maximum scar diameter of 0.45 mm, as measured by ASTM
D6079 or ISO 12156-1, or a minimum of 3100 grams, as measured by ASTM
D6078. Contact your fuel supplier for details.
Changing Fuel Filter
The fuel filter (P, F i g . 8 3 ) is located in the
fuel line before the fuel pump. Access the
fuel filter by opening the engine cover and
tilting the platform. See “Tilting Up the
Platform” on page 107. Replace the fuel
filter at the interval specified in the
“Maintenance Schedule” on page 104
The fuel filter is located on the left side of
the loader.
1. Perform the “Mandatory Safety Shut-
down Procedure” on page 10.
2. Allow the machine to cool completely.
Fuel spilled on hot components can cause fire
and severe burns. Allow the machine to cool
completely before removing the fuel filter.
