1. Biodiesel fuel (BDF)
B0-B20 biodiesel fuels (BDF)
You can use mixed diesel fuels containing 20% or less
biodiesel under the following conditions.
IMPORTANT :
• 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 (that is 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.
You can find more information about qualified
marketer(s)
and producer(s) at http://
www.bq-9000.org .
Preparation
• Before using BDF concentrations greater than B5,
you are advised to replace the engine oil, the
engine-oil-filter, and the fuel filter with new oil and
filters. For replacement procedures, see SERVICE
INTERVALS on page 74.
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 flow of fuel filter 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 the biodiesel whose concentrations
higher than 20% (that is greater than B20).
Higher concentrated biodiesel will affect the engine
performance and the 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 obtains
a thicker consistency (that is 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 do 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
spilling BDF 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 maintain 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.
Maintenance Requirements when using BDF B0
through B5
Follow recommended oil-change-intervals.
(See SERVICE INTERVALS on page 74)
Extended oil-change-intervals may result in premature
wear or engine damage.
Maintenance Requirements when using BDF B6
through B20
The maintenance interval for fuel related parts
changes.
See the following table for the new maintenance
interval.
