GENERAL INFORMATION
General Precautions
Dangerous substances
Modern vehicles contain many materials and liquids
which if not handled with care can be hazardous to
both personal health and the environment.
WARNING: Many liquids and other substances
used in motor vehicles are poisonous and should
under no circumstances be consumed and
should, as far as possible, be kept from contact
with the skin. These liquids and substances
include acid, anti-freeze, asbestos, brake fluid,
fuel, windscreen washer additives, lubricants,
refrigerants and various adhesives.
Always read carefully the instructions printed on
labels or stamped on components and obey them
implicitly. Such instructions are included for
reasons of your health and personal safety.
Never disregard them.
Synthetic rubber
Many 'O' rings, seals, hoses, flexible pipes and other
similar items which appear to be natural rubber, are
in fact, made of synthetic materials called
Fluoroelastomers. Under normal operating
conditions this material is safe and does not present
a health hazard. However, if the material is damaged
by fire or excessive heating, it can break down and
produce highly corrosive Hydrofluoric acid.
Contact with Hydrofluoric acid can cause serious
burns on contact with skin. If skin contact does occur:
lRemove any contaminated clothing
immediately.
lIrrigate effected area of skin with a copious
amount of cold water or limewater for 15 to 60
minutes.
lObtain medical assistance immediately.
Should any material be in a burnt or overheated
condition, handle with extreme caution and wear
protective clothing (seamless industrial gloves,
protective apron etc.).
Decontaminate and dispose of gloves immediately
after use.Lubricating oils
Avoid excessive skin contact with used lubricating
oils and always adhere to the health protection
precautions.
WARNING: Avoid excessive skin contact with
used engine oil. Used engine oil contains
potentially harmful contaminants which may
cause skin cancer or other serious skin
disorders.
WARNING: Avoid excessive skin contact with
mineral oil. Mineral oils remove the natural fats
from the skin, leading to dryness, irritation and
dermatitis.
Health protection precautions
The following precautions should be observed at all
times.
lWear protective clothing, including impervious
gloves where practicable.
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
lDo not put oily rags in pockets.
lAvoid contaminating clothes (particularly those
next to the skin) with oil.
lOveralls must be cleaned regularly. Discard
heavily soiled clothing and oil impregnated
footwear.
lFirst aid treatment should be obtained
immediately for open cuts and wounds.
lApply barrier creams before each work period to
help prevent lubricating oil from contaminating
the skin.
lWash with soap and water to ensure all oil is
removed (proprietary skin cleansers and nail
brushes will help).
lUse moisturisers after cleaning; preparations
containing lanolin help replace the skin's natural
oils which have been removed.
lDo not use petrol/gasoline, kerosene, diesel
fuel, oil, thinners or solvents for cleaning skin.
lWhere practicable, degrease components prior
to handling.
lIf skin disorders develop, obtain medical advice
without delay.
lWear eye protection (e.g. goggles or face
shield) if there is a risk of eye contamination.
Eye wash facilities should be provided in close
vicinity of the work area.

Air Conditioning Compressor
Replacement
A new compressor is supplied filled with a full charge
(X cm3) of refrigerant oil.

+ CAPACITIES, FLUIDS AND
LUBRICANTS, Capacities.A calculated quantity of
oil must be drained from the new compressor before
fitting. To calculate the quantity of oil to be drained:
1Remove the drain plug from the old
compressor.
2Invert the compressor and gravity drain the oil
into a calibrated measuring cylinder. Rotate the
compressor clutch to ensure the compressor is
completely drained.
3Note the quantity of oil drained (Y cm
3).
4Calculate the quantity of oil to be drained from
the new compressor using the following
formula:
X cm
3 — (Y cm3 + 20 cm3) = Q cm3
5Remove the drain plug from the new
compressor and drain Q cm3 of oil. Fit and
tighten the compressor drain plug.
Body Repairs
General
Body shells are of welded construction and bolted to
a chassis frame. Front and rear sections of the shell
are designed as 'energy absorbing' zones. This
means they are designed to deform progressively
when subjected to impact in order to minimise the
likelihood of injury to vehicle occupants.
It is essential that design dimensions and strength
are restored in accident rectification. It is important
that neither structural weakness nor excessive local
stiffness are introduced into the vehicle during body
repair.
Repairs usually involve a combination of operations
ranging from straightening procedures to renewal of
individual panels or panel assemblies. The repairer
will determine the repair method and this decision will
take into account a balance of economics between
labour and material costs and the availability of repair
facilities in both equipment and skills. It may also
involve considerations of the vehicles' downtime,
replacement vehicle availability and repair turn-
around time.
It is expected that a repairer will select the best and
most economic repair method possible, making use
of the facilities available. The instructions given are
intended to assist a skilled body repairer by
expanding approved procedures for panel
replacement. The objective is to restore the vehicle
to a safe running condition by carrying out a repair
which is as close as is feasible to original standard.
The results should not advertise to the experienced
eye that the vehicle has been damaged, although the
repair might not be identical in all respects to the
original factory build. Commercial bodyshop repair
facilities cannot always duplicate methods of
construction used during production.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and suspension
geometry checked after completion. Where
necessary a road test of the vehicle should be carried
out, particularly where safety-related items are
concerned.
Where major units have been disconnected or
removed it is necessary to ensure that fluid levels are
checked and topped up where necessary. It is also
necessary to ensure that the repaired vehicle is in a
roadworthy condition in respect of tyre pressures,
lights, washer fluid etc.
