Always reduce the engine speed to idle before disconnecting the jump leads.
Before removing the jump leads, switch on the heater blower (high) or the heated rear screen, to reduce the voltage peak
when the leads are removed.
Always disconnect the jump leads in the reverse order to the connecting sequence and take great care not to short the ends of
the leads.
Do not rely on the generator to restore a discharged battery. For a generator to recharge a battery, it would take in excess of 8
hours continuous driving with no additional loads placed on the battery.
Component Cleaning
To prevent ingress of dirt, accumulations of loose dirt and greasy deposits should be removed before disconnecting or
dismantling components or assemblies.
Components should be thoroughly cleaned before inspection prior to reassembly.
Cleaning Methods:
Dry Cleaning
Removal of loose dirt with soft or wire brushes
Scraping dirt off with a piece of metal or wood
Wiping off with a rag
CAUTION: Compressed air is sometimes wet so use with caution, especially on hydraulic systems.
Blowing dirt off with compressed air (Eye protection should be worn when using this method)
Removal of dry dust using vacuum equipment. This method should always be used to remove friction lining material
dust (asbestos particles)
Steam Cleaning
Calibration of Essential Measuring Equipment
WARNING: Failure to comply may result in personal injury or damage to components.
It is of fundamental importance that certain essential equipment e.g. torque wrenches, multimeters, exhaust gas analysers,
rolling roads etc., are regularly calibrated in accordance with the manufacturers instructions.
Use of Control Modules
Control modules may only be used on the vehicle to which they were originally installed. Do not attempt to use or test a
control module on any other vehicle.
Functional Test
On completion of a maintenance procedure, a thorough test should be carried out, to ensure the relevant vehicle systems are
working correctly.
Preparation
Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed, blank off
any exposed openings using grease-proof 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 oil ways, 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 associated 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, labels, containers and locking wire before dismantling a
component.
Dismantling
Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic systems
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, oil ways and fluid passages with compressed air.
WARNING: Do not permit compressed air to enter an open wound. Always use eye protection when using compressed air.
Make sure that any O-rings used for sealing are correctly reinstalled or renewed if disturbed. Mark mating parts to make sure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of causing
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 make sure

General Information - Health and Safety Precautions
Description and Operation Published: 11-May-2011
The Health and Safety Precautions subsection refers to some commonly used chemicals and materials, hazards associated with
their use, and safety measures to be taken. Some of these chemicals may be included in the following list either in their own
right or as an ingredient in a sealer or adhesive.
Acids and Alkalis
See also Battery Acids.
e.g. caustic soda, sulphuric acid.
Used in batteries and cleaning materials.
Irritant and corrosive to the skin, eyes, nose and throat. Cause burns. Can destroy ordinary protective clothing.
Avoid splashes to the skin, eyes and clothing. Wear suitable protective impervious apron, gloves and goggles. Do not breath
mists.
Ensure access to eye wash bottles, shower and soap are readily available for splashing accidents.
Display Eye Hazard sign.
Air Bags
See also Fire, Chemical Materials - General
Highly flammable, explosive – observe No Smoking policy.
Used as a part of the Supplemental Restraint System (SRS), mounted in various positions around the vehicle.
The inflator contains a high-energetic propellant which, when ignited, produces a VERY HOT GAS (2500° C).
The gas generant used in air bags is Sodium Azide. This material is hermetically sealed in the module and is completely
consumed during deployment. No attempt should be made to open an air bag inflator as this will lead to the risk of exposure
to Sodium Azide. If a gas generator is ruptured, full protective clothing should be worn when dealing with the spillage.
After normal deployment, gloves and safety goggles should be worn during the handling process.
Deployed air bags should be disposed of in a plastic bag in accordance with local regulations at an approved chemical waste
site.
Following any direct contact with gas generant.
Wash affected areas thoroughly with water
Seek medical assistance if necessary
WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted
before repairing or replacing any SRS components. To deplete the backup power supply energy, disconnect the battery negative
cable and wait for one minute. Failure to follow this instruction may result in personal injury.
NOTE: The storage, transportation, disposal and/or recycling of air bag modules must be carried out in accordance with all
applicable federal, state and local regulations including, but not limited to, those governing building and fire codes,
environmental protection, occupational health and safety and transportation.
Air Bags - Do's
Do store in an air bag safe when not installed to the vehicle.
Do store modules in an upright position
Do keep modules dry
Do carry modules with the cover side pointing away from the body
Do place modules with their cover side upwards
Do carefully inspect modules for damage
Do stand to one side when connecting modules
Do make sure all test equipment is properly calibrated and maintained
Do wash you hands after handling deployed air bags
Do wear safety glasses when carrying out repairs to the SRS or when handling an air bag module
Only carry out a system test with the air bag modules fully installed
Do inspect the condition of the impact sensor mounting bracket and sensor flylead if the vehicle has been involved in
an impact. Replace if damaged, even if there has been no deployment.
Air Bags - Do Nots
Do not store highly flammable material together with modules or gas generators
Do not store gas generators at temperatures exceeding 80° C

First Aid
Apart from meeting any legal requirements it is desirable for someone in the workshop to be trained in First Aid procedures.
Splashes in the eye should be flushed carefully with clean water for at least ten minutes.
Soiled skin should be washed with soap and water.
Individuals affected by inhalation of gases, fumes etc. should be removed to fresh air immediately. If effects persist, consult a
doctor.
If liquids are swallowed inadvertently, consult a doctor giving the information on the container or label. Do not induce vomiting
unless this action is indicated on the label.
Fluoroelastomer
See Viton.
Foams - Polyurethane
See also Fire.
Used in sound and noise insulation. Cured foams used in seat and trim cushioning.
Follow manufacturer's instructions.
Unreacted components are irritating and may be harmful to the skin and eyes. Wear gloves and goggles.
Individuals with chronic respiratory diseases, asthma, bronchial medical problems, or histories of allergic diseases should not
work in or near uncured materials.
The components, vapors or spray mists can cause direct irritation, sensitivity reactions and may be toxic or harmful.
Vapors and spray mists must not be inhaled. These materials must be applied with adequate ventilation and respiratory
protection. Do not remove the respirator immediately after spraying, wait until the vapor/mists have cleared.
Burning of the uncured components and the cured foams can generate toxic and harmful fumes. Smoking, naked flames or the
use of electrical equipment during foaming operations and until vapors/mists have cleared should not be allowed. Any heat
cutting of cured foams or partially cured foams should be conducted with extraction ventilation.
Freon
See Air Conditioning Refrigerant.
Fuels
See also, Fire, Legal Aspects, Chemicals and Solvents.
Avoid skin contact with fuel where possible. Should contact occur, wash the affected skin with soap and water.
Gasoline (Petrol)
Highly flammable - observe No Smoking policy.
Swallowing can result in mouth and throat irritation and absorption from the stomach can result in drowsiness and
unconsciousness. Small amounts can be fatal to children. Aspiration of liquid into the lungs e.g. through vomiting, is a very
serious hazard.
Gasoline dries the skin and can cause irritation and dermatitis on prolonged or repeated contact. Liquid in the eye causes
severe pain.
Motor gasoline may contain appreciable quantities of benzene, which is toxic upon inhalation, and the concentration of
gasoline vapors must be kept very low. High concentrations will cause eye, nose and throat irritation, nausea, headache,
depression and symptoms of drunkenness. Very high concentrations will result in rapid loss of consciousness.
Ensure there is adequate ventilation when handling and using gasoline. Great care must be taken to avoid the serious
consequences of inhalation in the event of vapor build up arising from spillages in confined spaces.
Special precautions apply to cleaning and maintenance operations on gasoline storage tanks.
Gasoline should not be used as a cleaning agent. It must not be siphoned by mouth. See First Aid.
Gas - oil (Diesel Fuel)
See warnings and cautions in relevant manual sections.
Combustible.
