Maintenance: Fuel system
50
Fuel system
Use only fuel recommended in the fuel specifications below. Always observe cleanliness when refuelling and
working with the fuel system.
All work concerning the engine injection pump or injectors is to be carried out at an authorized workshop. Break-
ing the seal on the injection pump will void the warranty.
WARNING! Fire hazard. Work performed on the fuel system must be done on a cold engine. Fuel spill on
hot surfaces or electrical components can cause fires. Keep fuel-drenched rags where they are safe in case
of fire.
Fuel specification
Fuel must comply with national and international stan-
dards at the least, e.g.:
EN590 (with national environment and cold require-
ments)
ASTM-D975-No 1-D, 2-D
JIS KK 2204
Sulfur content
Complying with legal requirements in each country. If
the sulfur content exceeds 0.5 wt%, service intervals
must be changed, see “Maintenance: Lubricating sys-
tem”.
Fuels with low density (city diesel) can result in a loss
of power by approx. 5% and an increase in fuel con-
sumption of approx. 2–3 %.
Fuel delivery pipes
The delivery pipes must not be bent, twisted or exert-
ed to any other forces. Change delivery pipes that are
damaged.
WARNING! Fire hazard! The fuel delivery pipes
must not be bent, twisted or exerted to any other
forces.
