II - ADVICE TO BE FOLLOWED BEFORE ANY
OPERATION
1) Carry out the work in a clean working area and take
care to protect removed components from dust using
plastic bags which are hermetically-resealable, for ex-
ample.
2) Always order the following from the Parts Depart-
ment before carrying out work:
-a new set of blanking plugs, specific to the engine,
-enough lint-free cleaning cloths.
-one of the two cleaning products for fuel pipe
unions,
-the parts that are always to be replaced after each
removal operation, mentioned in the operational pro-
cedures specific to the vehicle (see related Workshop
Repair Manual).
3) Wear safety goggles fitted with side shields to pre-
vent the cleaning product from splashing the eyes.
4) Wear leaktight protective gloves (Nitrile type) to
avoid prolonged contact with the skin.
5) Before carrying out work on the injection system,
use plastic bags or clean rags, for example, to protect:
-the accessories and timing belts,
-the electrical accessories (starter, alternator, power-
assisted steering pump, sensors and electrical con-
nectors),
-the flywheel face.
III - INSTRUCTIONS TO BE FOLLOWED DURING
THE OPERATION
Wash your hands before and while carrying out the
work.
Replace leaktight protective gloves (Nitrile type) when
they are soiled or damaged.
All components removed from the injection system
must be stored in a hermetically sealed plastic bag
once they have been capped.
Reseal the bag hermetically, for example using adhe-
sive tape, even if the bag must be opened shortly after-
wards: ambient air can be a source of impurities.After opening the fuel circuit, the use of brushes, clean-
ing agents, air blow guns, rifle-type brushes or stan-
dard cloths is strictly prohibited: these items are likely
to allow impurities to enter the system.
When replacing a component with a new one or when
refitting it after storing it in a plastic bag, do not unpack
it until it is time to fit it on the vehicle.
IV - CLEANING
There are currently two procedures for cleaning the
fuel circuit before opening it in order to carry out work in
the workshop.
These procedures enable the fuel circuit to be cleaned
to prevent contamination from entering: they both have
the same end result and neither is preferred over the
other.
1 - Cleaning using injector cleaner
Clear the access to the unions that need opening, fol-
lowing the work procedures specific to the vehicle (see
the relevant Workshop Repair Manual).
Protect sections which are sensitive to fuel leaks.
Pour the injector cleaning agent into a container which
is free from impurities.
Dip a clean brush, which is not shedding bristles, into
the container of injector cleaning agent.
Clean the unions carefully using the brush and the in-
jector cleaning agent.
Blast the components that have been cleaned with
compressed air (tools, workbench, and also parts,
unions and around the injection system). Check that no
bristles from the brush have come away and that the
area is clean.
Wipe the sections that were cleaned with fresh clean-
ing cloths.
Open the circuit at the unions and immediately fit the
relevant blanking plugs. Note:
When using leather protective gloves, wear a pair of
leaktight protective gloves (Nitrile type) over the top.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.
