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.
WARNING: Many of the fluids used in motor
vehicles, such as coolant, brake fluid and power
steering fluid, are inflammable. Take care not to
spill fluids when topping-up, a fire may result. If
spillage does occur, ensure the area is
thoroughly cleaned before starting the engine.
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 which 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 over-heated
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
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:
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
lWear protective clothing, including impervious
gloves where practicable.
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.
lUse barrier creams: apply before each work
period to help prevent lubricating oil from
contaminating the skin.
lWash with soap and water to ensure all oil is
removed (propriety 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, kerosene, diesel fuel, gas, oil,
thinners or solvents for cleaning skin.
lIf skin disorders develop, obtain medical advice
without delay.
lWhere practicable, degrease components prior
to handling.
lWear eye protection (e.g. goggles or face
shield) if there is a risk of eye contamination.
Eye wash facilities should be provided in the
close vicinity of the work area.
GENERAL INFORMATION

Brake hydraulics
Observe the following recommendations when
working on the brake system:
lAlways use two spanners when loosening or
tightening brake pipe or hose connections.
lEnsure that hoses run in a natural curve and are
not kinked or twisted.
lFit brake pipes securely in their retaining clips
and ensure that the pipe run cannot contact a
potential chafing point.
lContainers used for hydraulic brake fluid must
be kept absolutely clean.
lDo not store hydraulic brake fluid in an unsealed
container, it will absorb water and in this
condition would be dangerous to use due to a
lowering of its boiling point.
lDo not allow hydraulic brake fluid to be
contaminated with mineral oil, or put new
hydraulic brake fluid in a container which has
previously contained mineral oil.
lDo not re-use hydraulic brake fluid previously
removed from the system.
lAlways use clean brake fluid or a recommended
alternative to clean hydraulic components.
lFit a blanking cap to a hydraulic union and a
plug to its socket, immediately after
disconnection of pipes and hoses to prevent the
ingress of dirt.
lAbsolute cleanliness must be observed when
working with hydraulic components.
lIt is imperative that the correct brake fittings are
used and that threads of components are
compatible.
Cooling system caps and plugs
Extreme care is necessary when removing engine
cooling system expansion tank caps and coolant
drain or bleed screws when the engine is hot, and
especially if it is overheated.
To avoid the possibility of scalding allow the engine
to cool before attempting coolant cap or plug
removal.
Environmental Precautions
General
This section provides general information which can
help to reduce adverse environmental impacts
incurred through the activities carried out in
workshops.
Emissions to air
Many of the activities that are carried out in
workshops emit gases and fumes which contribute to
global warming, depletion of the ozone layer and/or
the formation of photo-chemical smog at ground
level. By considering and controlling how the
workshop activities are carried out, these gases and
fumes can be minimised, thus reducing the damage
to the environment.
Exhaust fumes
Running car engines is an essential part of workshop
activities and exhaust fumes need to be ventilated to
atmosphere. However, the amount of time engines
are running and the position of the vehicle should be
carefully considered at all times, to reduce the
release of poisonous gases and minimise the
inconvenience to people living nearby.
Solvents
Some of the cleaning agents used are solvent based
and will evaporate to atmosphere if used carelessly,
or if cans are left unsealed. All solvent containers
should be firmly closed when not needed and solvent
should be used sparingly. Suitable alternative
materials may be available to replace some of the
commonly used solvents. Similarly, many paints are
solvent based and the spray should be minimised to
reduce solvent emissions.
Refrigerant
It is illegal to release any refrigerants into the
atmosphere. Discharge and replacement of these
materials from air conditioning units should only be
carried out using the correct equipment.
Checklist
Always adhere to the following:
Engines –
ldon't leave engines running unnecessarily;
lminimise testing times and check where the
exhaust fumes are being blown.

Electrical precautions
General
The following guidelines are intended to ensure the
safety of the operator and ensure the prevention of
damage to the electrical and electronic components
fitted to the vehicle. Where necessary, specific
precautions are detailed in the individual procedures
of this manual.
Equipment
Prior to commencing any test procedure on the
vehicle, ensure that the relevant test equipment is
working correctly and any harness or connectors are
in good condition. It is particularly important to check
the condition of the lead and plugs of mains operated
equipment.
Polarity
Never reverse connect the vehicle battery and
always ensure the correct polarity when connecting
test equipment.
High Voltage Circuits
Whenever disconnecting live ht circuits, always use
insulated pliers and never allow the open end of the
ht lead to contact other components, particularly
ECU's.
Exercise caution when measuring the voltage on the
coil terminals while the engine is running, high
voltage spikes can occur on these terminals.
Connectors and harnesses
The engine compartment of a vehicle is a particularly
hostile environment for electrical components and
connectors:
lAlways ensure electrically related items are dry
and oil free before disconnecting and
connecting test equipment.
lEnsure disconnected multiplugs and sensors
are protected from being contaminated with oil,
coolant or other solutions. Contamination could
impair performance or result in catastrophic
failure.
lNever force connectors apart using tools to
prise apart or by pulling on the wiring harness.
lAlways ensure locking tabs are disengaged
before disconnection, and match orientation to
enable correct reconnection.
lEnsure that any protection (covers, insulation
etc.) is replaced if disturbed.Having confirmed a component to be faulty:
lSwitch off the ignition and disconnect the
battery.
lRemove the component and support the
disconnected harness.
lWhen replacing the component, keep oily hands
away from electrical connection areas and push
connectors home until any locking tabs fully
engage.
Battery disconnection
Before disconnecting the battery, disable the alarm
system and switch off all electrical equipment. If the
radio is to be serviced, ensure the security code has
been deactivated.
CAUTION: To prevent damage to electrical
components, always disconnect the battery
when working on the vehicle's electrical system.
The ground lead must be disconnected first and
reconnected last.
CAUTION: Always ensure that battery leads are
routed correctly and are not close to any
potential chafing points.
Battery charging
Only recharge the battery with it removed from the
vehicle. Always ensure any battery charging area is
well ventilated and that every precaution is taken to
avoid naked flames and sparks.
Ignition system safety precautions
The vehicle's ignition system produces high voltages
and the following precautions should be observed
before carrying out any work on the system:
WARNING: Before commencing work on an
ignition system, ensure all high tension
terminals, adapters and diagnostic equipment
are adequately insulated and shielded to prevent
accidental personal contacts and minimise the
risk of shock. Wearers of surgically implanted
pacemaker devices should not be in close
proximity of ignition circuits or diagnostic
equipment.
