XE ENGINE FUEL SYSTEM

1-1

1.  SAFETY INSTRUCTIONS

Diesel fuel is an extremely flammable liquid, and
may not be exposed to open flames or brought
into contact with hot parts. The diesel fuel fumes
remaining in an empty fuel tank form an
extremely explosive mixture.

When the fuel pipes are being removed, a
quantity of fuel will escape. To keep this quantity
of fuel as limited as possible, unscrew the
fuel-tank cap to release any overpressure.
Any spilled fuel must be collected, bearing in
mind the risk of fire.

Do not run the engine in an enclosed or
unventilated area.
Make sure exhaust fumes are properly
extracted.

Maintain a safe distance from rotating and/or
moving components.

Various sorts of oil and other lubricants used on
the vehicle may constitute a health hazard.
This also applies to engine coolant, windscreen
washer fluid, refrigerant in air-conditioning
systems, battery acid and diesel fuel.
So avoid inhaling and direct contact.

Exhaust gases contain carbon monoxide.
Carbon monoxide is a deadly, colourless and
odourless gas, which, when inhaled, deprives
the body of oxygen, leading to asphyxiation.
Serious carbon monoxide poisoning may result
in brain damage or death.

It is recommended to always disconnect the
battery’s earth connection during repair or
maintenance activities for which the power
supply is not required.
