Safety Regulations
DIESEL
- Before handling fuel, filling the tank, etc., comply with
the following rules:
Never mix other types of fuel with diesel, such as petrol
or alcohol.
- ATTENTION -
IT IS FORBIDDEN TO REFUEL WITH THE ENGINE
SWITCHED ON.
Clean the area around the fuel cap. Fill the fuel tank at
the end of every day to reduce condensation during the
work break.
Water and sediment must be removed before they reach
the engine.
Do not use antifreeze to remove water from the diesel fuel.
Do not rely on the filter to remove water from the diesel fuel.
Never leave the fuel cap off and always lock. If you lose
the original cap, replace with an original spare part. Not
just any cap will fit.
Keep an eye on the fuel pump nozzle while filling the tank.
- ATTENTION -
DO NOT SMOKE DURING THE AFORESAID OPERATIONS.
Do not use a flame to inspect the fuel tank.
Do not fill the tank completely. Leave room for the fuel to
expand and immediately clean any spillage.
Before carrying out any welds on the tank or any components
in close contact with the tank, ensure there is no fuel inside.
If there are any fuel leaks due to breakages, stop the leak
as soon as possible and contact a DIECI service centre.
- ATTENTION -
AVOID INHALING DIESEL VAPOURS; THEY ARE
CARCINOGENIC AND A HEALTH HAZARD.
RECOMMENDED FUEL SPECIFICATIONS
To ensure good performance, use a high quality fuel. The
recommended fuel specifications are given below.
Cetane number 45 minimum.
Viscosity 2/4.5 centistokes at 40°C.
Density 0.8201860 kg/litre at 15°C
Sulphur Sulphur 0.20% in weight, maximum.
Distillation 85% at 350°C.
Cetane number
The cetane number indicates the ignition capacity.
Fuel with a lower cetane number may cause ignition pro-
blems when the engine is cold and could affect combustion.
Viscosity
The viscosity value indicates the flow resistance; engine
performance can be affected if the viscosity value is not wi-
thin the limits.
Density
A lower density reduces engine power, higher density
increases engine power and the smokiness of the exhaust fumes.
Sulphur
A high sulphur level wears out the engine and creates pollution.
Distillation
Distillation indicates the mixture of different hydrocarbons in
the fuel. A high proportion of light hydrocarbons might affect
the combustion specifications.
Fuel for low temperatures
If the engine needs to be used at temperatures below 0°C,
special winter fuels can be used. These fuels have a lower
degree of viscosity and restrict the formation of paraffin in
the fuel. The formation of paraffin prevents the fuel from
passing through the filter.
