Diesel oil is used as fuel for the engine:
• CEN EN 590 (2009)
• ASTM D 975-94: 1-D, 2-D
• ISO 8217 DMX
Note
The engine manufacturer recommends fuels with a sulphur
content not exceeding 0.0015 percent by weight.
Water and sediment in fuel should not exceed 200 mg/kg. Ash in
fuel should not exceed 0.01 percent by weight.
At ambient temperatures below 0 °C (32 °F), use winter
diesel fuel�
Mixing diesel with special additives is forbidden�
Use of biofuel (diesel fuel)
The use of the fuel mixture under the trade name of biodiesel
is in principle approved by the engine manufacturer for the en-
gine of this machine if it conforms to the specifications accord-
ing to EN 14214 or ASTM D6751. A fuel mixture with 5% portion
of biodiesel at most is acceptable.
Before using biodiesel in 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 biodiesel for information concerning
the condition under which it can be used.
The engine guarantee will be rejected when biodiesel is
used which does not correspond to the above mentioned
standards and when the fuel system or engine is dam-
aged due to the use of the improper biodiesel!
When biodiesel is used, the power can be reduced by
up to 12% depending on the used mixture of biodiesel�
Therefore, never adjust the engine or the injection pump
to increase the power� Never mix the fuel mixture by
yourself on the work site�
Biodiesel has a higher cloud point at low ambient tem-
peratures and therefore wax crystals form in the fuel,
which results in clogging of the fuel filter�
When biodiesel is used, it is necessary to shorten re-
placement intervals of the fuel filter�
When you start using biodiesel, corrosion and impurities
made on internal walls of the fuel tank will get separat-
ed� Impurities are carried away by the fuel to the filter
where they are caught and the filter must be replaced�
Biodiesel has a higher ability to absorb atmospheric
moisture and therefore the atmospheric moisture con-
denses on internal walls of the tank, which results in
higher content of water in the fuel, which must be more
frequently drained from the separator of the fuel filter�
This problem occurs more often in cold weather�
When biodiesel is used all the year round, it is necessary
to clean the fuel system with a clean diesel fuel for at least
30 minutes during operation of the engine before the
machine is shut down for longer than 3 months� Further,
it is necessary to drain off and clean the fuel tank, and
either fill with diesel fuel or minimise the occurrence of
moisture and limit the microbiological growth inside the
tank� Consult these measures with the fuel supplier�
