8.4 Diesel fuel

Use common diesel fuel with a sulfur
content of less than 0.5 %. If the sulfur
content is higher, oil has to be changed at
shorter intervals.
The following fuel specifications are
applicable:
* DIN 51 601
* Nato Codes F 54, F 75, and F 76
* BS 2869: A1 and A2 (observe sulfur
content with A2)
* ASTM D 975-81 : 1-D and 2-D
* VV-F-800a : DF-A, DF-1, and DF-2.
Note
See engine instruction manual.
At low temperatures,paraffin
precipitation can cause blocks in the fuel
system and disruptions in operation.
Below outside temperatures of 0 °C use
winter diesel fuel (to -15 °C). (This is
usually available at gas stations in good
time before the winter season begins.)
Diesel fuel with additives is frequently
offered for use at temperatures as low as
-20 °C („Superdiesel").
Note
Only mix in the tank. First put in the
required quantity of petroleum, then fill up.
See engine instruction manual.
Below -15 °C or -20 °C, petroleum must
be added.
If it is necessary to use summer diesel
fuel below 0 °C, petroleum can also be
added up to 60 %.
In most cases, adequate resistance to
low temperatures can be achieved by
adding a product to improve flow
properties (fuel additive). Consult your
engine service station.
Attention
The compressor must not be fuelled
with bio-diesel (DIN 51606) or
vegetable oil.
8.5 Coolant
Attention
Only operate the engine with coolant
(water with corrosion protection/
antifreeze fluid)!
Pure water may cause damage to the
cooler and the engine.
Only use corrosion inhibitors and
antifreezes recommended and
approved by the engine manufacturer!
Recommendation:
GARDNER DENVER ID-Nr. A92131840
Texaco: Havoline AFC
The coolant consists of 50% water and
50% corrosion protection/antifreeze fluid.
Use drinking water only.
Do not use sea, brackish, industrial, rain
or distilled water.
The coolant should be changed not less
frequently than every two years.
Products of differing product groups
must not be mixed!
8.6 Recommended lubricants for
the bogies
For relubrication use only lithium
saponified grease which fulfils the
following specifications:
* consistency groups (NLGI) 2
DIN 51818
* worked penetration 265-295
DIN ISO 2137
* dripping point > 180 °C
DIN ISO 2176
*
operational temperature
– 40 °C ... +140 °C
This corresponds to a DIN 51502
lubrication grease, designation KP2N-4U.
Greases with different thickeners
(soap base) must not be mixed.
Recommended grease: Fuchs Renolit
LZR 2.
