1.2 Overview of biodiesel fuel (BDF)

B0-B20 biodiesel fuels (BDF)

You can use mixed diesel fuels containing 20% or less biodiesel under the following conditions.

IMPORTANT

• Concentrations greater than B5 (5%) are not approved for common rail engines and engines with

aftertreatment device. Using concentrations greater than B5 (5%) can cause damage and reduce engine
life.

• Refuel and use the fuel with caution in order to avoid contact with the fuel and spillage that could create a

potential environmental or fire hazard. Wear appropriate protective equipment when refueling.

Applicable BDF

• You can use blended diesel fuels containing 6% through 20% BDF (B6-B20) which comply with American society

for testing and materials (ASTM) D7467 standard, as revised, without adversely affecting the performance and
durability of the engine and the components of the fuel system.

• Any mineral-oil-diesel-fuel, if used, must conform to ASTM D975 (or the European EN590) Standard, as revised.

B100 fuel used to generate biodiesel-blended-fuels must meet ASTM D6751 (or EN14214) Standard, as revised.
The final blended fuel B20 must conform to ASTM D7467 standard, as revised.
Straight-vegetable-oil is not allowed in any blended fuel.

• Allowable blended fuel is mineral-oil-diesel-fuel blended with B100 (for example 100% BDF).

The blended fuel ratio shall be less than 20% B100 and 80% or more diesel fuel.
Purchase the B100 source used for biodiesel blends from an accredited BQ-9000 marketer or producer.

Product warranty, emission, and other precautions

• The engine-emission-control-system was certified according to current regulations based on the use of non-BDF.

When using BDF, the owner is advised to check applicable local and federal emission regulations, and comply
with all of them.

• BDF may cause restricted or clogged fuel filters during cold weather conditions, resulting in the engine not

operating properly.

• BDF encourages the growth of microorganisms which may cause degradation of the fuel. Degradation of the fuel

may cause corrosion of the fuel line or reduce the fuel filter flow earlier than expected.

• BDF inherently absorbs moisture which may cause degradation of the fuel earlier than expected. To avoid

absorbing moisture of BDF, drain the water separator and the fuel-filter-port often.

• Do not use biodiesel whose concentrations higher than 20% (for example, greater than B20).

Higher concentrated biodiesel will affect engine performance and fuel consumption, and degradation of the fuel
system components may occur.

• Do not readjust the engine-fuel-control-system because readjusting it will violate the emission-control-levels for

which the equipment was approved.

• Compared with soybean-based and rapeseed-based feedstock, palm-oil-based feedstock has a thicker

consistency (for example, higher viscosity) at lower temperatures.
Consequently, palm-oil-based feedstock may reduce performance of the fuel filter, particularly during cold weather
conditions.

• The Kubota warranty, as specified in the Owner's Warranty Information Guide, only covers flaws in product

materials and workmanship. Accordingly, the Kubota warranty does not cover any problems that may arise due to
the use of poor quality fuels that fail to meet the preceding requirements, whether biodiesel or mineral-oil-based.

Routine using

• Avoid spilling BDF onto painted surfaces because this may damage the finish. If the fuel is spilled, immediately

wipe clean and flush with soapy water to avoid permanent damage.

• When using BDF, you are advised to keep a full tank of the fuel, especially overnight and during short term

storage, to reduce condensation within the tank. Be sure to tighten the fuel cap after refueling to prevent moisture
build up within the tank. Water in the biodiesel mixture will damage the fuel filters and may damage the engine
components.
