IMPERATIVE: Respect the safety and cleanliness requirements.
EGR valve.
Connect the tool [1]to the capsule union (1).
Apply several times in succession a vacuum of approx.0.6 barto activate the rod "a".
In abrupt reaction to the vacuum, the valve should close on its seating with a clicking
noise.

PARTICLE FILTER SAFETY AND CLEANLINESS REQUIREMENTS
General.
ESSENTIAL: Given the very high pressures prevailing in the fuel high pressure circuit (1600 Bars), respect the following regulations.
It is forbidden to smoke in the immediate proximity of the high pressure circuit during a repair.
Avoid working close to flames or sparks.When the engine is running:
Do touch the fuel high pressure circuit.
Always keep out of range of possible projections of fuel, which could cause serious injuries.
Do not place your hand near to any leak on the fuel high pressure circuit. After the engine has stopped, wait 30 seconds before starting any operation.
NOTE:The waiting time is necessary to allow the fuel high pressure circuit to return to atmospheric pressure.
Safety rules.
IMPERATIVE:Wait at least an hour before starting any repair on the exhaust line.
Forced regeneration of the particle filter:
Check that there are no aerosols or inflammable products inside the vehicle’s boot.
Wear high temperature gloves.
Connect the vehicle to a gas extractor approved for this type of operation.
IMPERATIVE: In the absence of the required installations, carry out the forced regeneration of the particle filter outside the workshop,
in a concreted area well away from any inflammable materials. Place the vehicle in the high position.

PARTICLE FILTER SAFETY AND CLEANLINESS REQUIREMENTS
Operations on the fuel additive circuit.
IMPERATIVE: For all operations on the additive circuit, wear protective goggles and gloves that are resistant to hydrocarbons.
The work area must be ventilated.
In the event of any significant dispersion of additive:
Wear a breathing mask for filtering the particles.
Recover as much of the product as possible.
Place the product thus recovered in an appropriately labelled container. Wash the soiled area with copious amounts of water.
Dispose of materials and solid residues in an authorised recovery point.
IMPERATIVE:The filling kit should be recycled following a repair. All «Eolys» additive containers that have been opened should be
disposed of.
Cleanliness rules.
ESSENTIAL: The operator should wear clean overalls.
Before working on the injection circuit, it may be necessary to clean the unions of the following sensitive components(see corresponding operations).
Fuel filter.
Fuel high pressure pump.
Fuel high pressure regulator.
Fuel high pressure common injection rail. Fuel high pressure piping. Diesel injector carriers.
IMPERATIVE: After dismantling, immediately blank the unions of the sensitive components with plugs, to prevent any ingress of impurities.
