TECHNICAL DATA
4.1 Bio-diesel
Text-module
Fuel grade
RME R ape seed- M ethyl- E ster,
PME V egetable oil- M ethyl- E ster fuel
according to DIN 51606 are fuels to be used.
Cold-pressed rape seed oil cannot be used.
Text-module
Maintenance intervals
Oil and oil filter change intervals should be hal-
ved.
After filling a few times with biodiesel, after ha-
ving used conventional diesel fuel, the fuel filter
must be replaced. Since biodiesel acts as a sol-
vent, diesel residues may block the fuel filter.
Text-module
Instructions for use
Biodiesel is suitable for winter temperatures
down to about -10 °C.
At temperatures below -10 °C, diesel fuel needs
to be added to prevent coagulation of the biodie-
sel. 50 % Diesel must be added per tank filling.
With temperatures below - 16 °C, use only die-
sel.
Biodiesel can be mixed in any proportion with
diesel fuel.
This may slightly reduce power output.
Fuel consumption can be slightly increased.
If the tractor is not going to be used for some
time (3 months or more), fill with diesel to pre-
vent the fuel injection pump from seizing.

Special features of biodiesel
Biodiesel is obtained from plant oil (mainly rape
seed oil) by means of a chemical process, where
the vegetable oil is mixed with methanol and
converted to biodiesel using a catalyst.
Biodiesel is virtually sulphur-free, and the engine
therefore produces almost no SO2 (sulphur di-
oxide).
The exhaust gases contain
- carbon monoxide
- hydrocarbons
- particulates (e.g soot)
than when using conventional diesel.
Biodiesel is biodegradable and does not endan-
ger ground and water in case of accidents.
4.2 Bio hydraulic oil
Text-module
Bio hydraulic oil qualities
Use bio-hydraulic fluid made from vegetable oil,
rape seed oil and synthetic oils, according to vis-
cosity standard ISO VG 32 - ISO VG 46.
NOTE:
Do not use polyglycol-based synthetic oils.
Text-module
Maintenance intervals
Oil and oil filter need to be changed every 1,000
operating hours or every year, whichever comes
first.
After changing over to bio hydraulic oil, change
hydraulic oil filter after approx. 10 - 15 operating
hours. BIO hydraulic oil has solvent properties
and may cause clogging of the filter in reaction
with normal oil.
Text-module
Instructions for use
Bio hydraulic oil is suitable for winter operations
in temperatures down to approx. - 15 °C.
Bio hydraulic oil may loose viscosity in outside
temperatures below -15 °C and prolonged pe-
riods of non-operation of the tractor. After a cold
start, allow a short warm-up time at medium en-
gine speed to ensure safe operation of the hy-
draulic steering and lifting gear. In conditions of
severe cold, it may be necessary to warm up the
whole tractor.
Avoid mixing bio-hydraulic fluid with other oils,
e.g with other, normal oil remaining in the sy-
stem, or by operating an external implement.
This may affect the positive environmental pro-
perties of the fluid, and will make it more difficult
to dispose of (it will then have to be considered
as special waste).
When disposing of oil, current legislation and the
instructions of the oil manufacturer are to be ob-
served.
A mixing of more than 10% may result in altera-
tions in viscosity and may lead to problems with
the valves.

Special features of bio hydraulic oil
It is biodegradable and ground and ground water
will not be affected in case of accidental spills.
IMPORTANT:
In spite of the high environmental compatibi-
lity of bio-hydraulic fluid, accidental spills
must always be reported.
