Fuel
Quality
You should only use commercially available brand
diesel fuel and ensure strict cleanliness when fill-
ing in.
Since this engine complies with the exhaust gas
standard acc. to EPA
1
Stage “TIER 4”, the use of
ultra-low sulphur diesel fuel is mandatory, if the
engine is operated within an area where compli-
ance with EPA is required.
The fuel provision should always be topped up in
due time, so that the tank will not run dry.
The following fuel specifications are permitted:
l EN 590
l ASTM D 975 1-D and 2-D
Winter fuel
For winter operation use only winter diesel fuel, to
avoid clogging because of paraffin separation. At
very low temperatures disturbing paraffin separa-
tion can also be expected when using winter diesel
fuel.
Mineral oil based hydraulic oil
The hydraulic system is operated with hydraulic oil
HV 32 (ISO) with a kinematic viscosity of 32 mm
2
/
s at 40°C (104 °F).
For topping up or for oil changes use only high-
quality hydraulic oil, type HVLP according to DIN
51524, part 3, or hydraulic oils type HV according
to ISO 6743/3. The viscosity index (VI) should be
at least 150 (observe information of manufactur-
er).
