Jaguar XJ (X350). Manual — part 26

Avoid splashes to the skin, eyes and clothing. Wear protective gloves, goggles and clothing if
necessary.

Ensure good ventilation when in use, avoid breathing fumes, vapors and spray mists and keep
containers tightly sealed. Do not use in confined spaces.

When spraying materials containing solvents, e.g. paints, adhesive, coatings, use extraction
ventilation or personal respiratory protection in the absence of adequate general ventilation.

Do not apply heat or flame except under specific and detailed manufacturer's instructions.

Sound Insulation

See Fibre Insulation, Foams.

Suspended Loads

CAUTION: Never improvise lifting tackle.

There is always a danger when loads are lifted or suspended. Never work under an
unsupported, suspended or raised load e.g. suspended engine, etc.

Always make sure that lifting equipment such as jacks, hoists, axle stands, slings, etc., are
adequate and suitable for the job, in good condition and regularly maintained.

Transmission Brake Bands

Underseal

Viton

In common with many other manufacturers' vehicles, some components fitted to the Jaguar
range have 'O' rings, seals or gaskets which contain a material known as 'Viton'.

Viton is a fluoroelastomer, that is a synthetic rubber type which contains Fluorine. It is
commonly used for 'O' rings, gaskets and seals of all types. Although Viton is the most well
known fluoroelastomer, there are others, including Fluorel and Tecmoflon.

When used under design conditions fluoroelastomers are perfectly safe. If, however, they are
exposed to temperatures in excess of 400º C, the material will not burn, but will decompose,
and one of the products formed is hydrofluoric acid.

This acid is extremely corrosive and may be absorbed directly, through contact, into the body.

'O' rings, seals or gaskets which have been exposed to very high temperatures will appear
charred or as a black sticky substance.

DO NOT, under any circumstances touch them or the attached components.

Enquiries should be made to determine whether Viton or any other fluoroelastomer has been
used in the affected 'O' ring, seal or gasket. If they are of natural rubber or nitrile there is no
hazard. If in doubt, be cautious and assume that the material may be Viton or any
fluoroelastomer.

If Viton or any other fluoroelastomers have been used, the affected area should be
decontaminated before the commencement of work.

Disposable heavy duty plastic gloves should be worn at all times, and the affected area
washed down using wire wool and a limewater (calcium hydroxide) solution to neutralize the
acid before disposing of the decomposed Viton residue and final cleaning of the area. After
use, the plastic gloves should be discarded carefully and safely.

Welding

See also Fire, Electric Shock, Gas Cylinders.

Welding processes include Resistance Welding (Spot Welding), Arc Welding and Gas
Welding.

Resistance Welding

This process may cause particles of molten metal to be emitted at a high velocity, and the eyes
and skin must be protected.

Arc Welding

This process emits a high level of ultra - violet radiation which may cause arc - eye and skin
burns to the operator and to other persons nearby. Gas - shielded welding processes are
particularly hazardous in this respect. Personal protection must be worn, and screens used to
shield other people.

CONTACT LENS WEARERS ARE ADVISED TO REVERT TO ORDINARY
SPECTACLES WHEN ARC WELDING as the arc spectrum is believed to emit microwaves
which dry out the fluid between the lens and the eye. This may result in blindness when the
lens is removed from the eye.

Metal spatter will also occur, and appropriate eye and skin protection is necessary.

The heat of the welding arc will produce fumes and gases from the metals being welded, the
rods and from any applied coatings or contamination on the surfaces being worked on. These

gases and fumes may be toxic and inhalation of these should be avoided. The use of extraction
ventilation to remove the fumes from the working area may be necessary particularly in cases
where the general ventilation is poor, or where considerable welding work is anticipated. In
extreme cases or confined spaces where adequate ventilation cannot be provided, air-fed
respirators may be necessary.

Gas Welding (and Cutting)

Oxy - acetylene torches may be used for welding and cutting, and special care must be taken
to prevent leakage of these gases, with consequent risk of fire and explosion.

The process will produce metal spatter and eye and skin protection is necessary.

The flame is bright, and eye protection should be used, but the ultra - violet emission is much
less than that from arc welding, and lighter filters may be used.

The process itself produces few toxic fumes, but such fumes and gases may be produced from
coatings on the work, particularly during cutting away of damaged body parts, and inhalation
of the fumes should be avoided.

In brazing, toxic fumes may be produced from the metals in the brazing rod, and a severe
hazard may arise if brazing rods containing cadmium are used. In this event particular care
must be taken to avoid inhalation of fumes and expert advice may be required.

SPECIAL PRECAUTIONS MUST BE TAKEN BEFORE ANY WELDING OR CUTTING
TAKES PLACE ON VESSELS WHICH HAVE CONTAINED COMBUSTIBLE
MATERIALS, E.G. BOILING OR STEAMING OUT OF FUEL TANKS.

Warning Symbols on Vehicles

Decals showing warning symbols will be found on various vehicle components.

These decals must not be removed. The warnings are for the attention of owners/operators and
persons carrying out service or repair operations on the vehicle.

The most commonly found decals are reproduced below together with an explanation of the
warnings.

1 . Components or assemblies displaying the warning triangle and open book symbol advise
consultation of the relevant section of the owners handbook before touching or attempting

adjustments of any kind.

2 . Components or assemblies displaying the warning triangle with the electrified arrow and
open book symbol give warning of inherent high voltages. Never touch these with the engine
running or the ignition switched on. See Electric Shock in this subsection.

3 . Jaguar vehicles and replacement parts which contain asbestos are identified by this
symbol. See Asbestos in this subsection.

4 . Components or assemblies displaying this symbol give warning that the component
contains a corrosive substance. See Acids and Alkalis in this subsection.

5 . Vehicles displaying the caution circle with a deleted lighted match symbol, caution against
the use of naked lights or flames within the immediate vicinity due to the presence of highly
