2 - Using the brake 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.
Spray the brake cleaner onto the unions to be opened.
Clean the unions carefully using fresh cleaning cloths.
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.
Open the circuit at the unions and immediately fit the
relevant blanking plugs.WARNING
To prevent impurities from entering, once the fuel
circuit is opened, it must not be blasted with com-
pressed air. Use cleaning cloths only, if necessary.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.
WARNING
To prevent impurities from entering, once the fuel
circuit is opened, it must not be blasted with com-
pressed air. Use cleaning cloths only, if necessary.
