working with the fuel system.
All work concerning the engine injection pump or injectors is to be carried out at an authorised workshop. Break-
ing the seal on the injection pump will void the warranty.

hot surfaces or electrical components can cause fires. Keep fuel-drenched rags where they are safe in case
of fire.

dards at the least, e.g.:
EN590 (with national environment and cold require-
ments)
ASTM-D975-No 1-D, 2-D

of power by approx. 5% and an increase in fuel con-
sumption of approx. 2–3 %.

erted to any other forces. Change delivery pipes that
