8.3.2.2 Winter fuel
For winter operation use only winter diesel fuel, to avoid clogging
because of paraffin separation.
At very low temperatures disturbing paraffin separation can also be
expected when using winter diesel fuel.
Diesel fuels suitable for temperatures down to -44 °C (-47 °F) are
available for Arctic climates.
NOTICE!
Danger of engine damage!
– The admixture of petroleum and the addition of
“flow enhancing additives” (fuel additives) is
not permitted.
8.3.2.3 Storage
Even traces of zinc, lead and copper can cause deposits in the
injection nozzles, especially in modern Common-Rail injection sys-
tems.
Zinc and lead coatings in refuelling systems and fuel lines are not
permitted.
Copper containing materials (copper lines, brass items) should be
avoided, because they can cause catalytic reactions in the fuel with
subsequent depositing in the injection system.
8.3.3 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).
When refilling or changing oil, use only hydraulic oil type HVLP
according to DIN 51524, part 3, or hydraulic oil type HV according
to ISO 6743/4.
The viscosity index must be at least 150 (observe information of
manufacturer).
8.3.4 Lubrication grease
For lubrication purposes use an EP-high pressure grease, lithium
saponified (penetration 2), acc. to DIN 51502 KP 2G.
