IMPORTANT
Use the diagnostic tool before any operation is car-
ried out on the injection circuit to check:
- that the rail is not under pressure,
- that the fuel temperature is not too high.
Working on the circuit with the engine running is
strictly forbidden.
IMPORTANT
Be careful when removing the injectors or the injec-
tion rail as there will be a quantity of fuel in the rail
and the union.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
WARNING
To prevent impurities from entering the circuit, place
protective plugs on all fuel circuit components
exposed to the open air.
