WARNING: FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G.
TRICHLOROETHANE, WHITE SPIRIT, SBPB, METHYLENE CHLORIDE, PERCHLORETHYLENE.
DO NOT SMOKE IN THE VICINITY OF VOLATILE DEGREASING AGENTS.
Adhere strictly to handling and safety instructions given on containers and labels. Keep oils and solvents away from
naked flames and other sources of ignition. Do not apply heat in an attempt to free seized nuts or fittings; as well as
causing damage to protective coatings, there is
a risk of damage from stray heat to electronic equipment and brake
lines. Do not leave tools, equipment, spilt oil etc. around or on work
area. Wear protective overalls and use barrier
cream when necessary.
0 A3.1.1 Used Engine Oils
Prolonged and repeated contact with mineral oil will result in the removal of natural oils from the skin, leading to dry- ness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause
skin cancer. Washing facilities and adequate means of skin protection should be provided.
A3.1.2 Health Protection Precautions
0 Avoid prolonged and repeated contact with oil; particularly used engine oils.
o Wear protective clothing, including impervious gloves where practicable
0 Do not put oily rags in pockets.
0 Avoid contaminating clothes, particularly underwear, with oil.
0 Overalls must be cleaned regularly. Discard unwashable clothing and footwear which is oil impregnated.
o First Aid treatment should be obtained immediately for open cuts or wounds.
0 Use barrier creams, applying before each work period, to enable easier removal of dirty oil / grease from the
skin.
0 Wash with soap and water to ensure that all oil is removed (skin cleaner and a nail brush will help). The use of
preparations containing lanolin will help to replace the natural skin oils which have been removed.
o Do not use petrol, kerosene, gas oil, thinners or solvents for washing skin.
0 If skin disorders develop, obtain medical advice immediately.
0 Where practicable, degrease components prior to handling.
0 Where there is a risk of fluids coming into contact with the eyes, eye protection should be worn, for example,
goggles or a face shield. An eye wash facility should be provided.
A3.1.3 Environmental Protection Precautions
A3.1 SAFETY PRECAUTIONS
Whenever possible, use a ramp or pit whilst working beneath a car, in preference to jacking. Position chocks at the
wheels as well as applying the handbrake. Never rely on a jack alone to support a car. Use axle stands, or blocks care- fully placed at the jacking points, to provide a rigid location. Checkthat any lifting equipment used has adequate capac- ity and is fully serviceable. Ensure that a suitable form of fire extinguisher is conveniently located.
When using
electrical tools and equipment, inspect the power lead for damage and check that it is properly earthed. Disconnect
the earth (grounded) terminal of the car battery. Do not disconnect any pipes of the air conditioning refrigeration sys-
tem unless you are trained and instructed to do so. A refrigerant is used which can cause blindness if allowed to come
into contact with the eyes. Ensure that adequate ventilation is provided when volatile degreasing agents are being
It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses. The burning of used engine
oil in small space heaters or boilers is not recommended unless emission control equipment is fitted. Dispose of used
oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation trade.
If in doubt, contact the Local Authority for advice on disposal facilities.

General Fitting Instructions
A3.2 GENERAL FITTING INSTRUCTIONS
A3.2.1
Always fit covers to protect the wings before commencing work in the engine compartment. Cover the seats and
carpets, wear clean overalls and wash hands or wear gloves before working inside the car. Avoid spilling hydraulic
fluid, anti
-freeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use poly- thene sheets in the boot to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or fitting caps.
Precautions Against Damage To The Vehicle
A3.2.2 Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed,
blank off any exposed openings using greaseproof paper and masking tape. Immediately seal fuel, oil and hydraulic
lines when separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends
of oilways, exposed by component removal, with tapered hardwood plugs or readily visible plastic plugs. Immediately
a component is removed, place
it in a suitable container; use a separate container for each component and its asso- ciated parts. Before dismantling a component, clean it thoroughly with a recommended cleaning agent: check that the
agent will not damage any of the materials within the component. Clean the bench and obtain marking materials, la-
bels, containers and locking wire before dismantling a component.
A3.2.3 Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic
system are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems. Clean all tapped holes, crevices, oilways and fluid passages with compressed air.
WRNIFLG: DO NOT PERMIT COMPRESSED AIR TO ENTER AN OPEN WOUND. ALWAYS USE EVE PROTECTION
WHEN USING COMPRESSED AIR.
Ensure that any 'O'-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of caus- ing distortion or the initiation of cracks, which could occur if a center punch or scriber were used. Wire together mating
parts where necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to
be renewed and to parts requiring further inspection before being passed for reassembly.
Place labelled parts and other parts for rebuild
in separate containers.
Do not discard a part which is due for renewal until it has been compared with the new part, to ensure that the correct
part has been obtained.
A3.2.4 Inspection
Before inspecting a component for wear or performing a dimensional check, ensure that it is absolutely clean; a slight
smear of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures
quoted for
it, use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The
use of makeshift equipment can be dangerous. Reject a component if its dimensions are outside the limits quoted,
or if damage is apparent. A part may be refitted if its critical dimension is exactly to the limit size and it is otherwise
satisfactory. Use Plastigauge 12 Type PG-1 for checking bearing surface clearance e.g. big end bearing shell to crank
journal. Instructions for the use of Plastigauge and a scale giving bearing clearances in steps of
0,0025 mm (0.0001
in) are supplied with the package.

Body Systems & Body Repair
A4.1.5 GENERAL REPAIR NOTES
The following advice should be noted before ANY repair work is carried out.
0 Disconnect the vehicle battery ground lead (disconnect the alternator where electric welding is used) and take
note of the reconnection procedures as detailed in Section 15.
0 Where structural parts are straightened or renewed, a body alignment / straightening jig must be used.
0 Where appropriate, structural sections should be straightened by cold processes. Heat, especially excessive
heat, will reduce the strength of steels.
0 Repairs may only be carried out successfully, and any warranties protected, if genuine Jaguar replacement parts
and Jaguar approved materials are used.
0 Tools, procedures and facilities must be right for the job. Do not compromise the quality of the work by using
inappropriate methods.
0 All trim and electrical components in the locality of the repair must be removed or disconnected prior to panel
removal / replacement; this is especially important where hollow sections may contain harnesses, tubes or
foam, see section
A4.3.5.
0 The welding and gas processes detailed in the following sections are the only ones recommended by Jaguar
Cars Ltd.
0 Ensure that you have read and understood the safety related procedures in this and other relevant sections.
WARNING: DO NOT WORK
IN THE VICINITY OF A LIVE AIR BAG, REMOVE IT COMPLETELY. READ WORKING PRAC- TICES AIR BAG, SECTION 15. ANY SEAT BELT WHICH HAS BEEN WORN IN AN ACCIDENT MUST BE RENEWED. PLEASE SEE SECTION
AGE LOCATIONS. 13 FOR IMPORTANT INFORMATION REGARDING 'TEAR LOOP' SEAT BELTS / BUCKLES AND ANCHOR-
CAUTION: Electric arc welding should not be used on Jaguar vehicles. The high vottages produced by this process will cause irreparable damage to the electrical control and microprocessor systems.
A4.1.5.1 Welding and Gas Processes Special Notes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated,
metal.
The flanges of panels which are to be welded together must be clean, corrosion free and treated as appropriate,
with either weld-through primer or inter-weld sealer; use only materials and processes in accordance with the 'Body Seal-
ing and Preservation Manual' and relevant application areas in section A4.3.1.1.
See 'Zinc Coated Panels' section A4.2.
Generally, the resistance spot welding equipment used in the motor vehicle repair industry does not produce a weld
of equivalent strength to that of the manufacturer. Therefore, the expression 'single row of resistance spot welds'
means that the spots should be spaced on a pitch of
19mm to 25mm. This will usually result in more spot welds than
found in the original factory joint.
To remove resistance spot welds, a resistance spot weld cutter should be used.
If the new joint is to be MIG plug welded, the old resistance spot welds should be cut from the panel which is to be
retained and those holes used for plug welding.
Suitable holes may also be drilled or punched;
8,O mm dia for sections up to 1,6 mm, and 10,O mm dia for thicker sec- tions.
