3.2. Specification of fluids
3.2.2. Fuel
Diesel is used as fuel:
• CEN EN 590:96
• ASTM D 975-94: 1-D, 2-D
• ISO 8217 DMX
NOTE
Engine producer recommends to use fuel with sulphur content
less than 0.05 weight percent.
Therefore use winter Diesel fuel at outdoor tempera-
tures below 0 °C (32 °F).
Mixing diesel with special additives is prohibited.
Use of biofuel (Diesel fuel)
Using the fuel mixture under the trade name of Bionafta is in
principle approved by the engine manufacturer for the engine
on the machine if it conforms to the specifications under EN
14214 or ASTM D6751. Up to 5 % portion of biodiesel is accept-
ed.
Before using Bionafta on the machine, make sure that it is sup-
plied by a reputable supplier who supplies fuels corresponding
to the above-mentioned standards.
Always ask the supplier of Bionafta for information concerning
the condition under which it can be used.
Guarantee for the engine will be rejected when using
Bionafta not conforming to the above-mentioned stand-
ards and if the fuel system or engine is damaged as a re-
sult of using improper Bionafta!
When using Bionafta, power can be reduced by up to 12%
depending on the used mixture of Bionafta. Therefore,
do not adjust the engine or the setting of the injection
pump for increasing the power in any case. Never mix the
fuel mixture at the place of use.
Bionafta has a higher cloud point at a low ambient tem-
perature, which leads to the creation of wax crystals in
the fuel resulting in the fuel filter clogging.
When using Bionafta, it is necessary to shorten the inter-
vals of the engine oil exchange and replacement of an oil
filter and fuel filter.
When changing over to Bionafta, the action of Bionafta
releases corrosion and impurities created on the fuel
tank internal walls. Impurities are brought by the fuel to
the filter catching them and the filter must be replaced
afterwards.
Bionafta has a higher ability to absorb atmospheric
moisture, which results in the condensation of atmos-
pheric moisture on the internal walls of the tank and
a higher content of water in the fuel and the need for
more frequent discharging of water from the fuel filter
separators. The possibility of the occurrence of the prob-
lem increases in cold weather.
If Bionafta (Biodiesel) is used all the year round, it is nec-
essary to clean the fuel system under the engine opera-
tion with a clean diesel fuel for at least 30 minutes before
parking the machine for longer than 3 months. Further,
it is necessary to drain off the fuel tank, clean it, and ei-
ther fill it with diesel fuel or minimise the occurrence of
moisture and limit the microbiological growth inside the
tank. Consult the measures with the fuel supplier.
