2.6.3 Fuel recommendation
The diesel fuel must meet the requirements of EN 590 and ASTM D975 respectively.
The use of other fuels as well as the mixing with additives is only permitted after consultation with
the engine manufacturer.
Bio diesel:
According to EN 590 and ASTM D975, a specific portion of bio diesel is permitted in the fuel.
Depending on the country of origin, bio diesel can be produced from different plant materials and
thus have different properties.
Affected by temperature, atmospheric oxygen and time, these bio diesel components in the fuel
may decompose in the fuel and thus cause damages within the fuel system.
Engine without exhaust treatment:
To comply with emission regulations, diesel engines fitted with an exhaust gas treatment system
must be operated only with a sulphur-free diesel fuel. Compliance with the emission requirements
but also the durability of the individual exhaust gas treatment components is not assured if this re‐
quirement is ignored!
The following fuel specifications are approved:
■ Diesel fuels according to EN 590
─ (≤0.0010% Sulphur – EU: Level IIIB and higher)
■ Diesel fuels according to ASTM D975
─ (≤0.0015% Sulphur – EPA: Tier 4 interim and higher)
Never store fuel in galvanised containers!
The fuel must be filtered before it is filled into the machine when it has been supplied in bar‐
rels or canisters. This procedure prevents fault in the fuel system cause by contamination.
2.6.4 Engine coolant recommendation
In fluid-cooled engines, the cooling fluid must be treated and monitored to prevent engine damage.
Water quality:
An important factor for treating the cooling fluid is the correct water quality.
