Diesel
When the engine is taken into operation the en-
gine oil must be analysed every 50 hours to de-
termine the correct oil change interval. The oil
analysis must be carried out according to the Oil
analysis section in this Operator's manual.
Bear in mind that the emission limit for the cur-
rent engine type may limit the maximum permit-
ted sulphur content of the fuel.
Temperature dependency of
the fuel
At temperatures lower than those specified for
the fuel, paraffin wax may precipitate from the
fuel and block filters and pipes. The engine can
then lose power or stop.
The fuel is adapted for use in the specific climate
of each country. If a vehicle or an engine is to be
operated in a temperature zone with a tempera-
ture lower than normal, first identify the temper-
ature properties of that particular fuel.
The properties of the fuel when cold can be im-
proved by adopting one of the following meas-
ures before the temperature drops:
• Install an electric fuel heater if this particular
fuel is not suitable for the expected tempera-
ture and no fuel is available with the correct
temperature properties.
• Add 0.5-2% alcohol (isopropanol) to prevent
any water in the fuel from freezing and form-
ing plugs of ice. Drain fuel tanks and drain or
renew fuel filters regularly.
IMPORTANT!
Mixing kerosene or other paraffins with the fuel
is prohibited. The injectors may be damaged.
Mixing petrol with the fuel is prohibited. In the
long term petrol can cause wear in the injectors
and engine.
