5.22 - FUEL HANDLING, STORAGE AND
SPECIFICATION
5.22.1 - Gas-oil
Before handling fuel, filling tanks etc., observe the follow-
ing:
Under no circumstance should gasoline, alcohol, gasohol or
dieselhol (a mixture of diesel fuel and alcohol) be added to
diesel fuel because of increased fire or explosion risks. In a
closed container such as a fuel tank they are more explo-
sive than pure gasoline. DO NOT use these blends. Addi-
tionally, dieselhol is not approved due to possible
inadequate lubrication of the fuel injection system. Clean
the filler cap area. Fill the tank at the end of each day to re-
duce overnight condensation.
• Never take the cap off or refuel with the engine running
or hot.
• When filling the tank, keep control of the nozzle.
• DO NOT smoke.
• Don't fill the tank to its full capacity. Allow room for
expansion and wipe up spilt fuel immediately.
• If the original cap is lost, replace it with an AGCO cap
and tighten securely. A cap made by a different manu-
facturer may not be suitable.
• Keep equipment properly maintained.
CAUTION: Diesel fuel is very inflammable.
Handle fuel with care. Keep away from naked
flames. Do not smoke when filling the tank or
when filling the engine. Do not leave the
engine when filling the tank. Clean up any fuel which
may have been split. Any material which comes into
contact with the fuel must be moved to a safe place.
If high pressure fuel comes into contact with the skin,
immediately wash with clean water and obtain medi-
cal assistance.
5.22.1.1 - Recommended fuel specification
The diesel fuel used must meet DIN EN 590 standard. To
get the correct power and performance from your engine,
use good quality fuel. The recommended fuel specification
for engines is indicated below:
• Cetane No. 45 minimum.
• Viscosity 2.0… 4.5 mm2/s at 40°C.
• Density 0.820/0.860 kg/litre at 15°C.
• Sulphur 0.20% of mass, maximum.
• Distillation 85% at 350°C.
• Water content maximum 200 mg/Kg.
Cetane Number
Cetane number indicates ignition performance. A fuel with
a low cetane number can cause cold start problems and af-
fect combustion.
Viscosity
Viscosity is the flow resistance; engine performance can
be affected if it is outside the specified limits.
Density
A lower density reduces engine power, a higher density in-
creases engine power and exhaust smoke.
Sulphur
A high amount of sulphur can cause engine wear.
Distillation
Distillation is an indication of the mixture of different hydro-
carbons in the fuel. A high ratio of light-weight hydrocar-
bons can affect the combustion characteristics.
Low Temperature Fuel
Special winter fuels may be available for engine operation
at temperatures below 0°C. These fuels have a lower vis-
cosity and also limit the wax formation in the fuel at low
temperatures. If wax formation occurs, this could stop the
fuel flow through the filter. If you need advice on engine
setting or lubricating oil change periodicity due to the qual-
ity of the available fuel, consult your nearest Dealer.
