INJECTION
SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Engines: HDi ALL TYPES
SAFETY REQUIREMENTS.
Preamble.
All interventions on the injection system must be carried out to conform with the following requirements and regulations:
Competent health authorities.
Accident prevention.
Environmental protection.
WARNING:Repairs must be carried out by specialised personnel informed of the safety requirements and of the precautions to be taken.
Safety requirements.
IMPERATIVE: Take into account the very high pressures in the high pressure fuel circuit (1350 bars), and respect the requirements below: No smoking in proximity to the high pressure circuit when work is being carried out.
Avoid working close to flame or sparks.
Engine running: Do not work on the high pressure fuel circuit.
Always stay clear of the trajectory of any possible jet of fuel, which could cause serious injuries.
Do not place your hand close to any leak in the high pressure fuel circuit.
After the engine has stopped, wait
30 secondsbefore any intervention.
NOTE:This waiting time is necessary in order to allow the high pressure fuel circuit to return to atmospheric pressure.

INJECTION
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.
