Biodiesel Fuel (Diesel Vehicles Only)

Biodiesel fuel has unique qualities that should be considered before it is used in the Kubota D722 diesel
engine. Review the warranty section for warranty information. During cold weather, plugged fuel lines,
plugged fuel systems, hard starting, and other unknown failures can result from use of this fuel.

Biodiesel fuel is an excellent medium for microbial growth and contamination. Microbial contamination can
cause contamination and corrosion of the fuel system and prematurely plugged fuel filters.

See following

NOTE.

NOTE:

Use of Biodiesel fuel may result in premature failure of fuel system components. Kubota has doc-
umented problems such as plugged fuel filters and deteriorated fuel lines during testing of Biodie-
sel fuel.

Biodiesel fuel can damage painted surfaces. Be sure to remove all spilled fuel immediately to help prevent
damage to painted surfaces.

If Biodiesel fuel will be used in the Kubota D722 engine, be sure that it meets the following requirements:

•

The fuel mixture can include no more than 5% Biodiesel fuel in the mineral oil diesel fuel.

•

Biodiesel fuel to be blended must meet the EN14214 standard, and the mineral oil diesel fuel to be
blended must meet the EN590 standard. The final B5 product (95/5% mix) must also comply with the
EN590 standard.

See following NOTE.

NOTE:

For more information on these fuel standards, please contact your nearest Kubota dealer.

If Biodiesel fuel is used, be sure to apply the following guidelines:

•

Ensure the fuel tank is as full as possible at all times to prevent moisture from collecting.

•

Ensure that the fuel tank cap is securely tightened to prevent water from entering the fuel tank.

•

Drain all water from the fuel filter daily before operating the vehicle.

See Draining Water from Fuel Fil-

ter.

•

Check the engine oil level daily before the engine is started.

See Engine Oil Level Check on page 34.

•

Before vehicle storage, run the engine with conventional diesel fuel for at least 30 minutes to flush the
Biodiesel fuel from the engine.

See Preparing the Vehicle for Extended Storage on page 27.
