Health and Safety
It is the duty of both employer and employee to ensure safe working conditions and practices. Correct safety procedures
and equipment must be applied to any potential hazards that are notified, or identified by an operator.
Employees must observe local legislation go verning working conditions and practices at all times and must always act in a
responsible manner in the workplace. In the event of personal injury resulting from any workshop activity, medical help
should be obtained as soon as poss ible. Self-treatment other than by first aid, should not be attempted.
WARNING: READ AND UNDERSTAND WORKING PRACTICE S CONCERNING CLIMATE CONTROL SYSTEMS, SECTION
412, WITH SPECIAL REGARD TO: REFRIGERANT MUST NEVE R BE DIRECTLY VENTED TO ATMOSPHERE. ALWAYS USE
JAGUAR APPROVED RECOVERY / RECYCLE / RECHARGE EQUI PMENT, WEAR SUITABLE EYE AND SKIN PROTECTION AND
OBSERVE ALL APPLICABLE SAFETY REQUIREMENTS.
With the constant introduction of new materials in the manufacture of vehicles, an awareness of the potential risks and
appropriate precauti ons is important.
Notification of Hazards
Symbols, which convey important information, will be positioned at the beginning of any specific operation or text. Standard symbols will be used where repairs or service procedures ar e detailed. All symbols will conform to standard ANSI Z535.3
(American National Standards Institute). The surround shape of the symbol will indicate the basis of the message to be
conveyed (see top three elements of ?) The icon depicting the message will be within the surrounding shape. Once
nominated the icon will retain its meaning.
POTENTIAL RISKS
Paint
Organic solvents, found in paints, may caus e damage or severe irritation to liver, kidneys, digestive tracts and respiratory
system if inhaled over long pe riods of time. Prolonged exposure to isocyanate s can cause lung sensitization with asthma-like symptoms developing on subsequent exposure to even low concentrations of isocyanates. Solvent inhalation can cause
dizziness or loss of consciousness and inhalation of spray dust and sanding debris may cause lung damage.
Spillage or splashes of solvents, paint ac tivators and additives can cause dermatitis or eye injury. Contact with peroxide or
acid catalysts can cause serious burns.
Applied Heat (Welding)
There is considerable risk of damage to eyes and skin if welding or flame cutting is attempted without using the correct
protective equipment. Many materials or fluids within vehicles are highly flammable and toxic and dangerous fumes may
also be liberated if heat is applied to expanded foam, corr osion protection, trim and seat materials, paints containing
isocyanates, and adhesive and sealing compounds.
When heated to a temperature of 300°C, polyurethane based compounds may liberate small quantities of isocyanate. Many
types of nitrogen containing chemicals ma y be liberated as breakdown products which can contain isocyanates, oxides of
nitrogen and hydrogen cyanide.
Potentially toxic or asphyxiant fumes and gases produced when welding include zinc oxide from zinc coated panels, and
ozone gas from the MIG process.
Metal Repair
There is considerable risk of damage to eyes, ears and skin wh en cutting, forming, or dressing metal. Soldering operations
can also be hazardous due to heat generated fumes and the risk of skin contact with hot materials.
PRECAUTIONS

Paint
The inhalation of sprays, fumes, or dust during paint application or sanding processes should always be avoided. Ensure
that there is efficient ventilation / extrac tion at all times. Paint spraying should be confined as far as possible to spray
booths. Personnel with a history of asth ma should not be employed in any process involving the use of isocyanates.
Operators working in a spray booth where isocyanate material is present must use air-fed breathing equipment with air
supplied to the visor at the re commended pressure and filtered to remove oil, water, and fumes. Operators involved in
handling mixing or spraying should wear protective clothing including gloves and goggles, to avoid skin and eye contact.
Particle masks or canister type respir atosr should be worn when sanding.
Applied Heat
When welding, flame cutting, brazing etc, the operator shou ld use as appropriate, goggles, mask / fume extractor and
flameproof protective clothing. It is especially important when working with polyurethane compounds to use air-fed
breathing equipment. Appropriat e fire fighting equipment and personnel trai ned in its use must always be available.
Metal Repair
Appropriate eye and hand protection should be worn when sanding, drilling, cutting, chiselling, flatting or welding. Face
masks or air-fed visors should also be wo rn when sanding or flatting either body solder or fillers. On completion of a
soldering operation, swarf must be re moved from the work area and the operat or must wash his hands thoroughly.
GENERAL REPAIR NOTES
The following advice should be noted before any repair work is carried out.
Disconnect the vehicle battery gr ound lead (disconnect the alternator where electric welding is used) and take note of the
reconnection procedures as detailed in 86.15.15.
Where structural parts are straightened or renewed, a body alignment / straightening jig must be used. The application of
heat, especially excessive heat, reduces the strength of steels, where appropriate therefore, structural sections should be
straightened by cold processes.
Repairs may only be carried out successful ly, and any warranties protected, if genuine Jaguar replacement parts and Jaguar
approved materials are used.
The correct tools, procedures and facilities must always be us ed. The quality of the work must not be compromised by using
inappropriate methods or equipment.
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 sectio ns may contain harnesses, tubes or foam, see section A4.3.5.
WARNING: DO NOT WORK IN THE VICINITY OF A LIVE AIR BAG, REMOVE IT COMPLETELY. READ WORKING
PRACTICES AIR BAG, SECTION 20. ANY SEAT BELT WHICH HAS BEEN WORN IN AN ACCIDENT MUST BE RENEWED.
CAUTION: Electric arc welding should not be used on Jaguar vehicles. The high voltages produced by this process will
cause irreparable damage to the electric al control and microprocessor systems.
The following welding and gas processes are the only ones recommended by Jaguar Cars Ltd.
Welding and Gas Processes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated metal.
The flanges of panels to be welded toge ther, must be clean, corrosion free and tr eated as appropriate, with either weld-
through primer or inter-weld sealer. Only materials and processes specified in the 'Body Sealing and Preservation Manual'
should be used in the relevant application areas detailed in this section. Refer to 'Zinc Coated Panels' Section

ZINC COATED PANELS
Description
Approximately 70% of the 'body in white' (BIW) mass is made up of zinc coated panels.
• NOTE: To maintain the protective qualities of the zinc trea tment, repairs to any damaged coated area must be made as
soon as possible after the damage has occurred.
All exterior skin panels, with the exceptio n of the roof, are double side zinc plated and this coating (nominally 7,5 microns)
provides two way corrosion protection. Should the outer layer of paint become chipped with the zinc coating remain intact,
the zinc will oxidize on contact with air and being impermeable, this coat of oxidation will prevent corrosion damage of the
base metal. If the outer layer of paint and the zinc coating become damaged, the zinc rather than the base metal will react
with the air and 'sacrifice' itself to corrosion as a 'sacrificial anode'.
Welding Preparation
Contamination of the weld with resultant reduction in joint st rength increase and increased electrode tip dressing frequency
will occur zinc coating is not removed. In exceptional cases where the zinc coating must remain intact, the tip pressure and
welding current should be increased by 10 to 20%.
Where 'resistance spot welding' is employed, the zinc coatin g should be lightly abraded away on the mating surfaces and
those in contact with the electrode tips. Do not remove more zinc coating than is absolutely necessary.
Before welding, a weld-through primer or inter-weld sealer should be applied, as detailed in the Body Sealing and
Preservation manual.
Where MIG welding is used as an alternativ e to resistance spot welding for plug and butt welds or due to limited access, the
problems caused by the presence of zinc coating are much the same, with the added complication of increased weld spatter
and nozzle contamination.
Body Fillers
Conventional polyester fillers do not adhere satisfactorily to zinc plated panels, it is ther efore important that only those
products specifically designed for this application are used and the manufacturer's recommendations are followed.
Refinishing
Use only those products approved by Jaguar Cars Ltd and exercise special care on zinc coated panels.
As replacement panels ar e supplied ready primed, the only bare metal that needs to be exposed are those areas prepared
for welding etc, as decribed in 'Welding Preparation. Where any part of a panel is dressed back to the bare surface, it should
be treated with a zinc rich primer compatible with the paint application system.
GENERAL PREPARATION OF PANELS
Removal of Panels and Welds
• NOTE: Where other components must be removed for access, refer to the relevant manual section for guidance. This is
particularly important where steerin g, braking, suspension, electrical and safety systems are affected.
Expose all resistance spot welds, using a ro tary wire brush fitted to an air drill or a hand held wire brush on those that are
not clearly visible (1).
WARNING: DO NOT BURN UNDERSEAL OFF. USE A 'HOT KNIFE' OR SUITABLE SOLVENT.
Cut out spot welds using a Zipcutter or Roto-Bor (2). At this point it may be necessary to cut out the bulk of the panel using

a pneumatic saw (3).
• NOTE: On some panels, before removing the bulk with a pneumatic saw, it may be necessary to remove brazed areas and
MIG welded seams. Separate spot welded joints and remove the panel remnants.
Removal of Panels and Welds

PREPARATION OF PANEL SURFACES
WARNING: DO NOT BURN UNDERSEAL OFF. USE A 'HOT KNIFE' OR SUITABLE SOLVENT.
• NOTE: Observe all appropriate safety procedures.
Remove weld nuggets with a sander and 36 gr it disc and clean all flanges to a bright smooth finish (1). Straighten existing
panel joint edges as required.
Mark off the area of new panel and cut to size leaving approxim ately two inches overlap on the existing panel. Offer up new
panel or section, align with associated pa rts, i.e. new rear fender aligned with door / luggage compartment lid / backlight
aperture and clamp the panel into positi on.Where necessary, cut the new and orig inal panels to form a butt joint.
Release all clamps and remove the new panel. If required, apply inner panel protection and or sound insulation.
Prepare the new panel joint edges, including interior and exterior, for welding by cleaning to bright metal (1).
Apply weld-through primer or in terweld sealer(2) to all surfaces to be resistance spot welded.
Where appropriate, apply metal- to-metal adhesive or sealer (3) in accordance with the manufacturer's instructions.
