3.2. Media Specification
3.2.2. Fuel
The following Diesel oils are used as engine fuel:
EN 590
ASTM D 975-88: 1-D a 2-D
Therefore use winter Diesel fuel at out-
door temperatures below 0 °C (32 °F).
Special Diesel fuel with additives in-
tended for very low temperatures must
be used at outdoor temperatures below
-15 °C (5 °F) (”super Diesel”).
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.
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 standards and if
the fuel system or engine is damaged as
a result of using improper Bionafta!
! CAUTION !
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 ambi-
ent temperature, 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
intervals of the engine oil exchange and replace-
ment of an oil filter and fuel filter.
When changing over to Bionafta, the action of
Bionafta releases corrosion and impurities cre-
ated 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 at-
mospheric 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 oc-
currence of the problem increases in cold weather.
If Bionafta (Biodiesel) is used all the year round, it
is necessary to clean the fuel system under the en-
gine operation 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 either 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.
