FUEL ____________________________________________________________________
Diesel fuel is flammable. Use caution when you add the fuel to the mower.
Only use an approved container. The
spout on the container must fit inside the fuel filler neck. Never use the containers that are not approved to keep or
transfer fuel.
Fill the fuel tank to less than 25 mm (1 inch) below the filler neck.
Use clean Ultra low sulfur Diesel fuel to the recommended specification. The use of Diesel fuel additives is not
recommended. If fuel additives are used, the fuel additives must be approved for use in the engine type used in your
machine. Refer to the engine manual for additional information.
Check fuel hoses and clamps at service interval (see chart). Replace the fuel hoses and clamps at first indication of
wear or damage.
Keep the fuel according to your local, state or federal regulations. Below are some items you should be aware of.
WARNING
Refuel the mower before you start the engine. When the engine is in operation or while the engine is hot, never
remove the fuel cap or add fuel to the mower.
Refuel outdoors only and do not smoke when you add fuel.
If the fuel spills, do not try to start the engine, but move the mower away from the area. Until fuel vapors are
removed, do not allow sparks, open flame or other types of ignition.
Never keep fuel containers near an open flame or any device that can cause the ignition of fuel or fuel vapors.
Always tighten the fuel tank cap and container cap after you add fuel.
What you need to do
Reasons to do it
Inspect your Diesel fuel tank, pipes and fittings. If there
is Brass, Copper, Lead or Zinc in contact with the fuel,
plan to change the parts.
Low emission Diesel engines use higher pressure injection equipment. The
presence of Copper, Lead and Zinc in Diesel fuel can accelerate wear in fuel
pumps and injectors. Diesel fuel can absorb these metals when in prolonged
contact.
Check your fuel supplier is supplying ultra low sulfur
Diesel. It has to meet ASTM D975 S15 or EN590:2009
or equivalent fuel with a sulfur content of less than 15
ppm (parts per million)
Low emission Diesel engines, use Particle Filters (DPF). The use of high
sulfur fuel will block the DPF and damage the engine. Any engine damage
caused by high sulfur fuel is not covered by warranty.
Ask your fuel supplier if there are records showing the
amount of water mixed in with the Diesel fuel supplied.
Water in the fuel is harmful to the high-pressure injection equipment. Kubota
recommends that water content must not be more than 0.05%
Ensure that Bio content to your Diesel fuel does not
exceed 5% as described in ASTM D6751 or EN 14214
Higher Bio Diesel content has been proven to absorb more moisture from the
atmosphere. The moisture and Bio content can result in the development of
molds and bacteria. These accelerate the blocking of fuel filters.
Ask your fuel supplier to verify that fuel being delivered
meets the lubricity level required set in ASTM D6079
Low emission Diesel engines use higher pressure injection equipment. The
tolerances in the injection equipment require the fuel to provide lubrication.
Ask your fuel supplier to verify that fuel being delivered
has less than 1milligram of solid contaminant per liter
of fuel.
Any particles in the fuel can damage parts within the fuel injection system,
reducing performance. The vehicle fuel system will provide protection, but
the cleaner the fuel into the vehicle, the lower the chance of a particle by
passing the filtration system.
