3.2. Media specification
3.2.2. Fuel
Diesel oil is used as the engine fuel:
EN 590 •
ASTM D6078-78: 1-D and 2-D •
The ASTM 2D is recommended to use as optimal one.
Fuel viscosity shall be over 1,3 cST at 40 °C (104 °F) to provide
for fair characteristics of the liquidity and lubricating of the fuel
system components.
At ambient temperatures below 0 °C
(32 °F) you must use winter diesel oil.
At ambient temperatures below -15 °C
(5 °F) it will be necessary to use special
diesel oil with additives for these pur-
poses (”engine super diesel oil”).
NEVER use other fuels (e.g. bio diesel oil,
mixed bio diesel oil, LFO, etc.) than the
Diesel fuels specified above.
NEVER mix diesel oil with gasoline,
with alcohol. These mixtures may cause
explosion!
Do NOT use the portion of antifreeze
cooling agent in cooling liquid higher
than 50 % (point of congelation is -36 °C
[-34 °F], boiling point is 110 °C [228 °F])
unless badly required.
NEVER use the portion over 68 %!
We do NOT recommend to mutually
blend antifreeze agents. Mixing various
types of cooling liquid may cause loss of
anticorrosion properties.
Check the portion of antifreeze cooling
agent in cooling liquid with refractom-
eter always before winter season starts.
When mixing antifreeze cooling agent
based on nitrides with the agent based
on amines the health hazardous ni-
troamines will form.
3.2.3. Cooling liquid
Fill the engine cooling system with cooling liquid comprising 50
% of ethylene glycol antifreezing mixture and 50 % of water.
Do NOT use earthy (hard) water with higher content of calcium,
and magnesium which brings calculus formation, and with
higher content of chlorides and sulphates which causes cor-
rosion. Refer to CUMMINS Engine Operation and Maintenance
Manual. CUMMINS.
Max content of compounds of calcium and magnesium is 170
milligrams - hardness of water
Max content of compounds of chlorine is 40 milligrams
Max content of compounds of sulphur is 100 milligram
