Fire hazard. When carrying out work on the fuel system
make sure the engine is cold. A fuel spill onto a hot
surface or an electrical component can cause a fire.
Store fuel soaked rags so that they cannot cause fire.
IMPORTANT! Only use the grades of fuel
recommended in the fuel specification below, refer to
Technical Data, Fuel System. Always observe the
greatest cleanliness during re-fueling and work on the
fuel system.
IMPORTANT!
All work on the engine injection system must be done
by an authorized workshop.

The fuel system must be bled, e.g. after changing fuel
filter, if the fuel tank has been run dry and after long
stops.

2 Loosen the bolt.
3 Turn the engine over with the starter (max. 20 sec.)
until fuel free of bubbles comes out.
