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.
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 the 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.
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.
What you need to do
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.
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)
Ask your fuel supplier if there are records
showing the amount of water mixed in with
the Diesel fuel supplied.
Ensure that Bio content to your Diesel fuel
does not exceed 5% as described in ASTM
D6751 or EN 14214
Ask your fuel supplier to verify that fuel
being delivered meets the lubricity level
required set in ASTM D6079
Ask your fuel supplier to verify that fuel
being delivered has less than 1milligram of
solid contaminant per litre of fuel.
MAINTENANCE AND LUBRICATION 8
!
WARNING
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.
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.
Water in the fuel is harmful to the high-pressure injection
equipment. Kubota recommends that water content must not
be more than 0.05%
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.
Low emission Diesel engines use higher pressure injection
equipment. The tolerances in the injection equipment require
the fuel to provide lubrication.
Any particles in the fuel can damage parts within the fuel
injection system, reducing performance. The vehicle fuel sys-
tem will provide protection, but the cleaner the fuel into the
vehicle, the lower the chance of a particle by passing the fil-
tration system.
