IMPORTANT
Consult the safety and cleanliness advice and oper-
ation recommendations before carrying out any
repair (see 13B, Diesel injection, Diesel injec-
tion: Precautions for the repair, page 13B-1) .
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.
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
IMPORTANT
Wear leaktight gloves (nitrile type) for this opera-
tion.
WARNING
To prevent impurities from entering the circuit, place
protective plugs on all fuel circuit components
exposed to the open air.

WARNING
Before fitting a new high-pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high-pressure
pipe.
Do not lubricate high-pressure pipes supplied
without an applicator, as these high-pressure
pipes are self-lubricating.
