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.

SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Engines: HDi ALL TYPES
CLEANLINESS REQUIREMENTS.
Preliminary operations.
IMPERATIVE: The technician should wear clean overalls.
Before working on the injection system, it may be necessary to clean the apertures of the following sensitive components:(refer to corresponding procedures) Fuel filter.
High pressure fuel pump.
High pressure fuel injection common rail. High pressure fuel pipes
Diesel injector carriers.
IMPERATIVE: After dismantling, immediately block the apertures of the sensitive components with plugs, to avoid the entry of impurities.
Work area.
The work area must be clean and free of clutter.
Components being worked on must be protected from dust contamination.
