sulphur content has a negative effect on the oil
change intervals.
The fuel level should always be topped up in due time
so that the fuel tank is never run dry, as otherwise filter
and injection lines need to be bled.
Quality
The following fuel specifications are permitted:
l
EN 590
l
DIN 51628
l
ASTM D975 Grade-No. 1-D and 2-D.
l
JIS K 2204 Grade Fuel 1 and Grade Fuel 2 with lu-
brication properties acc. to EN 590
Winter fuel
For winter operation use only winter diesel fuel, to
avoid clogging because of paraffin separation. Diesel
fuels suitable for temperatures down to -44 °C are
available for Arctic climates. At very low temperatures
disturbing paraffin separation can also be expected
when using winter diesel fuel.
The admixture of petroleum and the addition of "flow
enhancing additives" (fuel additives) is not permitted.
Coolant
For fluid cooled engines the cooling fluid must be pre-
pared by admixing a cooling system protection agent
to the fresh water and should be checked within the
specified maintenance intervals.
This prevents damage caused by corrosion, cavita-
tion, freezing and overheating.
Fresh water quality
The correct quality of water is highly important when
preparing coolant. Clear and clean water within the
boundaries of the following analysis values should
generally be used.
Information concerning the water quality can be ob-
tained from the waterworks.
If the fresh water analysis values are unknown, these
must be determined with the help of a water analysis.
If the values of the analysis deviate, the water must be
treated accordingly.
l
pH-value too low:
Adding of caustic lye of soda or caustic potash so-
lution.
l
Water hardness too high:
Mix with soft, distilled or fully demineralized water
l
Chloride and/or sulphate too high:
Mix with distilled or fully demineralized water
l
Total hardness or carbonate hardness too low:
Mix with hardened water (harder water is in most
cases available in the form of drinking water).
!
Caution
Another analysis must be made after the fresh wa-
ter has been prepared.
Cooling system protection agent
As a protection against frost, corrosion and boiling
point anti-freeze agents must be used under any cli-
matic conditions.
Coolant for fluid cooled engines is prepared by adding
an ethylene-glycol based anti-freeze agent with corro-
sion inhibiting properties to the cooling water.
We therefore highly recommend our BOMAG cooling
system protection agent.
If our cooling system protection agent is not available
for any important reasons, you may, in exceptional
cases, use products that have been approved by the
engine manufacturer.
The list of approved cooling system protection agents
is also available in the Internet under the following ad-
dress:
Fresh water analysis values
pH-value at 20 °C
6.5 - 8.5
Chloride ion content (mg/l) (ppm) max. 100
Sulphate ion content (mg/l)
(ppm)
max. 100
Water hardness (ion content of
calcium and magnesium )
(mmol/l)]
max. 3.56
Conversion to other units:
- German degree (°dH)]
max. 20
- English degree (°eH)]
max. 25
- French degree (°fH)]
max. 36.5
corresponds with a content of
