INFORMATION FUEL HANDLING PRECAUTIONS
The following information provides basic precautions
which must be observed if fuel is to be handled safely.
It also outlines the other areas of risk which must not
be ignored.
This information is issued for basic guidance only, and
in any case of doubt, appropriate inquiries should be
made of your local Fire Officer or Fire Department.
Fuel vapour is highly flammable and in confined
spaces is also very explosive and toxic and when
diluted with air becomes a readily ignitable mixture.
The vapour is heavier than air and will always fall to
the lowest level. It can readily be distributed
throughout a workshop by air current, consequently,
even a small spillage of fuel is very dangerous.
Always have a fire extinguisher containingFOAM CO
2
GAS,orPOWDERclose at hand when handling fuel,
or when dismantling fuel systems and in areas where
fuel containers are stored.
WARNING: lt is imperative that the battery
is not disconnected during fuel system
repairs as arcing at the battery terminal
could ignite fuel vapour in the atmosphere.
Always disconnect the vehicle battery BEFORE
carrying out work on the fuel system.
Whenever fuel is being handled, transferred or
stored, or when fuel systems are being dismantled
all forms of ignition must be extinguished or
removed, any lead lamps used must be flame
proof and kept clear of spillage.
No one should be permitted to repair components
associated with fuel without first having had fuel
system training.Hot fuel handling precautions
WARNING: Before commencing any
operation requiring fuel to be drained from
the fuel tank, the following procedure must
be adhered to:
1.Allow sufficient time for the fuel to cool, thus
avoiding contact with hot fuels.
2.Vent the system by removing the fuel filler cap in
a well ventilated area. Refit the filler cap until the
commencement of fuel drainage.
Fuel transfer
WARNING: Fuel must not be extracted or
drained from any vehicle while it is
standing over a pit.
The transfer of fuel from the vehicle fuel tank must be
carried out in a well ventilated area. An approved
transfer tank must be used according to the transfer
tank manufacturer's instructions and local regulations,
including attention to grounding of tanks.
Fuel tank removal
AFUEL VAPOURwarning label must be attached to
the fuel tank upon removal from the vehicle.
Fuel tank repair
Under no circumstances should a repair to any tank
be attempted.

INFORMATION JACKING
The following instructions must be carried out before
raising the vehicle off the ground.
1.Use a solid level ground surface.
2.Apply parking brake.
3.Select 1st gear in main gearbox.
4.Select Low range in transfer gearbox.
CAUTION: To avoid damage occurring to
the under body components of the vehicle
the following jacking procedures must be
adhered to.
DO NOT POSITION JACKS OR AXLE STANDS
UNDER THE FOLLOWING COMPONENTS.
Body structure
Bumpers
Fuel lines
Brake lines
Front radius arms
Panhard rod
Steering linkage
Rear Trailing links
Fuel tank
Engine sump
Gearbox bell housing
Jack or support vehicle by axles only.
Vehicle jack
The jack provided with the vehicle is only intended to
be used in an emergency, for changing a tyre. Do
NOTuse the jack for any other purpose. Refer to
Owner's Manual for vehicle jack location points and
procedure. Never work under a vehicle supported by
the vehicle jack.
Hydraulic jack
A hydraulic jack with a minimum 1500 kg, 3,300 lbs
load capacity must be used, see J6083.
CAUTION: Do not commence work on the
underside of the vehicle until suitable axle
stands have been positioned under the
axle, see J6084.
Raise the front of the vehicle
1.Position cup of hydraulic arm under differential
casing.
NOTE: The differential casing is not
central to the axle. Care should be taken
when raising the front road wheels off the
ground as the rear axle has less sway stiffness.
2.Raise front road wheels to enable an axle stand
to be installed under left hand axle tube.

GENERAL FITTING REMINDERS

INFORMATION GENERAL FITTING REMINDERS
WORKSHOP SAFETY IS YOUR RESPONSIBILITY!
The suggestions, cautions and warnings in the
section are intended to serve as reminders for
trained and experienced mechanics. This manual
is not a definitive guide to automotive mechanics
or workshop safety.
Shop equipment, shop environment, and the use
and disposal of solvents, fluids, and chemicals
are subject to government regulations which are
intended to provide a level of safety. It is your
responsibility to know and comply with such
regulations.
PRECAUTIONS AGAINST DAMAGE
1.Always fit covers to protect fenders before
commencing work in engine compartment.
2.Cover seats and carpets, wear clean overalls
and wash hands or wear gloves before working
inside vehicle.
3.Avoid spilling hydraulic fluid or battery acid on
paint work. Wash off with water immediately if
this occurs. Use Polythene sheets to protect
carpets and seats.
4.Always use a recommended Service Tool where
specified.
5.Protect temporarily exposed screw threads by
replacing nuts or fitting plastic caps.SAFETY PRECAUTIONS
1.Whenever possible, use a lift when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
WARNING: Do not use a pit when
removing fuel system components.
2.Never rely on a jack alone to support vehicle.
Use axle stands carefully placed at jacking
points to provide rigid support.
3.Ensure that a suitable form of fire extinguisher is
conveniently located.
4.Check that any lifting equipment used has
adequate capacity and is fully serviceable.
5.Disconnect battery.
WARNING: Do not disconnect any pipes in
air conditioning system, unless trained
and instructed to do so. A refrigerant is
used which can cause blindness if allowed to
contact eyes.
6.Ensure that adequate ventilation is provided
when volatile degreasing agents are being used.
7.Do not apply heat in an attempt to free stiff
fixings; as well as causing damage to protective
coatings, there is a risk of damage to electronic
equipment and brake linings from stray heat.

INFORMATION PREPARATION
1.Clean components and surrounding area prior to
removal.
2.Blank off any openings exposed by component
removal using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.Observe scrupulous cleanliness when
dismantling components, particularly when
brake, fuel or hydraulic system parts are being
worked on. A particle of dirt or a cloth fragment
could cause a dangerous malfunction if trapped
in these systems.
2.Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
6.Do not discard a part due for renewal until it has
been compared with the new part, to ensure that
its correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.
