WARNING: Wait at least 30 seconds after the engine stops before commencing

any repair to the high-pressure fuel injection system. Failure to follow this instruction
may result in personal injury.

WARNING: Place the vehicle in a well ventilated, quarantined, area and arrange

"No Smoking/Fuel Fumes" signs about the vehicle.

WARNING: Before any work is carried out on the fuel system, ground the vehicle

to earth and maintain the ground connection until the work is complete.

WARNING: Do not carry out any repairs to the fuel injection system with the

engine running. The fuel pressure within the system can be as high as 1650 bar. Failure
to follow this instruction may result in personal injury.

WARNING: Do not smoke or carry lighted tobacco or open flame of any type

when working on or near any fuel related components. Highly flammable vapors are
always present and may ignite. Failure to follow these instructions may result in
personal injury.

WARNING: After carrying out repairs, the fuel system must be checked visually

for leaks. Failure to follow these instructions may result in personal injury.

WARNING: If taken internally do not induce vomiting, seek immediate medical

attention. Failure to follow these instructions may result in personal injury.

WARNING: If fuel contacts the eyes, flush the eyes with cold water or eyewash

solution and seek medical attention.

WARNING: Wash hands thoroughly after handling fuel, as prolonged contact

may cause irritation. Should irritation develop, seek medical attention.

WARNING: This procedure involves fuel handling. Be prepared for fuel spillage

at all times and always observe fuel handling precautions. Failure to follow these
instructions may result in personal injury.

CAUTION: Diesel fuel injection equipment is manufactured to very precise

tolerances and fine clearances. It is therefore essential that absolute cleanliness is
observed when working with these components. Always fit blanking plugs to any open
orifices or lines.

CAUTION: Always carry out the cleaning process before carrying out any

repairs to the fuel injection system components. Failure to follow these instructions may
result in foreign matter ingress to the fuel injection system.

CAUTION: The low-pressure fuel system bleeding procedure must be carried out

before this procedure is carried out, or the engine is attempted to be started, following
removal or replacement of any low-pressure fuel system component. Failure to follow
this instruction may result in damage to the fuel injection pump.

CAUTION: The engine must not be cranked using the starter motor for more

than 30 seconds. The starter motor must be allowed to cool for at least 5 minutes after
cranking for 30 seconds. Failure to follow these instructions will result in damage to the
starter motor.

NOTE:

If a new fuel filter is to be installed, make sure the fuel filter is installed AFTER the high-
pressure fuel system has been bled.

NOTE:

This procedure is necessary if the fuel injection pump, or the fuel line between the fuel
filter and the fuel injection pump is removed, drained of fuel or replaced.

1. Bleed the low-pressure fuel system.

CAUTION: Make sure that the high-pressure fuel supply line remains in contact

with the fuel injection supply manifold and fuel injection diverter rail until both unions
have been detached and cleaned. Failure to follow this instruction may result in foreign
matter ingress to the fuel injection system.
