disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc
player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the
battery in the event of a short circuit.

Reconnecting the Battery


WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating
sparks, and if in doubt cover the vent plugs or covers with a damp cloth.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or
damage to sensitive electrical equipment.

Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the
battery terminals are secure.
Restart the clock (where installed) and set it to the correct time.
Enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.

Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature
as the stored idle and drive values contained within the ECM have been lost. Allow the vehicle to idle for a further three
minutes. Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96
km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This will allow the ECM to relearn idle and drive values, and
may cause driveability concerns if the procedure is not carried out.

Connecting a Slave Battery Using Jump Leads


WARNING: If the slave battery has recently been charged and is gassing, cover the vent plugs or covers with a damp
cloth to reduce the risk of explosion should arcing occur when connecting the jump leads.
CAUTIONS:


A discharged battery condition may have been caused by an electrical short circuit. If this condition exists there will be
an apparently live circuit on the vehicle even when all circuits are switched off. This can cause arcing when the jump leads are
connected.


Whilst it is not recommended that the vehicle is jump started, it is recognized that this may occasionally be the only
practical way to mobilize a vehicle. In such an instance the discharged battery must be recharged immediately after jump
starting to avoid permanent damage.
Always make sure that the jump leads are adequate for the task. Heavy duty cables must be used.
Always make sure that the slave battery is of the same voltage as the vehicle battery. The batteries must be connected
in parallel.
Always make sure that switchable electric circuits are switched off before connecting jump leads. This reduces the risk
of sparks occurring when the final connection is made.




WARNING: Make sure that the ends of the jump leads do not touch each other or ground against the vehicle body at any
time while the leads are attached to the battery. A fully charged battery, if shorted through jump leads, can discharge at a rate
well above 1000 amps causing violent arcing and very rapid heating of the jump leads and terminals, and can even cause the
battery to explode.
Always connect the jump leads in the following sequence.
Slave battery positive first then vehicle battery positive.
Slave battery negative next and then vehicle ground at least, 300 mm (12 in) from the battery terminal e.g. engine
lifting bracket. www.JagDocs.com

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

Highly flammable, flammable - observe No Smoking policy

Pressurized Equipment

See High Pressure Air, Lubrication and Oil Test Equipment.

Solder

Solders are a mixture of metals such that the melting point of the mixture is below that of the constituent metals (normally
lead and tin). Solder application does not normally give rise to toxic lead fumes, provided a gas/air flame is used.
Oxy-acetylene flames should not be used, as they are much hotter and will cause lead fumes to be produced.

Some fumes may be produced by the application of any flame to surfaces coated with grease etc. and inhalation of these
should be avoided.

Removal of excess solder should be undertaken with care, to make sure that fine lead dust is not produced, which can give
toxic effects if inhaled. Respiratory protection may be necessary.
Solder spillage and filings should be collected and removed promptly to prevent general air contamination by lead.
High standards of personal hygiene are necessary in order to avoid ingestion of lead or inhalation of solder dust from clothing.

Solvents

See also Chemical Materials, Fuels (Kerosene), Fire.
e.g. acetone, white spirit, toluene, xylene, trichloroethane.

Used in cleaning and de-waxing materials, paints, plastics, resins, thinners etc.
Some may be highly flammable or flammable.
Skin contact will degrease the skin and may result in irritation and dermatitis following repeated or prolonged contact. Some
can be absorbed through the skin in toxic or harmful quantities.
Splashes in the eye may cause severe irritation and could lead to loss of vision.

Brief exposure to high concentrations of vapors or mists will cause eye and throat irritation, drowsiness, dizziness, headaches
and, in the worst circumstances, unconsciousness.

Repeated or prolonged exposure to excessive but lower concentrations of vapors or mists, for which there might not be
adequate warning indications, can cause more serious toxic or harmful effects.
Aspiration into the lungs (e.g. through vomiting) is the most serious consequence of swallowing.

Avoid splashes to the skin, eyes and clothing. Wear protective gloves, goggles and clothing if necessary.

Ensure good ventilation when in use, avoid breathing fumes, vapors and spray mists and keep containers tightly sealed. Do not
use in confined spaces.

When spraying materials containing solvents, e.g. paints, adhesive, coatings, use extraction ventilation or personal respiratory
protection in the absence of adequate general ventilation.
Do not apply heat or flame except under specific and detailed manufacturer's instructions.

Sound Insulation

See Fibre Insulation, Foams.

Suspended Loads


CAUTION: Never improvise lifting tackle.

There is always a danger when loads are lifted or suspended. Never work under an unsupported, suspended or raised load e.g.
suspended engine, etc.

Always make sure that lifting equipment such as jacks, hoists, axle stands, slings, etc., are adequate and suitable for the job,
in good condition and regularly maintained.

Transmission Brake Bands

See Asbestos.

Underseal

See Corrosion Protection.

Do not empty fuel while working in a workshop or a pit
Ensure that working area is well ventilated
Ensure that any work on the fuel system is only carried out by experienced and well qualified maintenance personnel
Ensure that fume extraction equipment is used where appropriate


Fume extraction equipment must be in operation when solvents are used e.g. Trichloroethane, white spirit, sbp3,
methylene chloride, perchlorethylene. Do not smoke in the vicinity of volatile degreasing agents.

Whenever possible, use a ramp or pit whilst working beneath a vehicle, in preference to jacking. Position chocks at the wheels
as well as applying the parking brake. Never rely on a jack alone to support a vehicle. Use axle stands, or blocks carefully
placed at the jacking points, to provide a rigid location. Check that any lifting equipment used has adequate capacity 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 vehicle battery. Do not disconnect any pipes of the air conditioning refrigeration system 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 used.

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 the work area. Wear protective overalls and use barrier cream when necessary.

Environmental Protection

In some countries it is illegal to pour used oil onto 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 installed. 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 Information - Standard Workshop Practices
Description and Operation

Protecting the Vehicle Published: 04-Jul-2014

Always install covers to protect the fenders before commencing work in the engine compartment. Always install the interior
protection kit, wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic
fluid, antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use polythene
sheets in the luggage compartment to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or installing caps.

Vehicle in Workshop

When working on a vehicle in the workshop always make sure that:

The parking brake is applied or the wheels are securely chocked to prevent the vehicle moving forwards or backwards
If the engine is to be run, there is adequate ventilation, or an extraction hose to remove exhaust fumes is installed
There is adequate room to jack up the vehicle and remove the wheels, if necessary
Fender covers are always installed if any work is to be carried out in the engine compartment
The battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle is jacked up


CAUTION: When electric arc welding on a vehicle, always disconnect the generator wiring to prevent the possibility of a
surge of current causing damage to the internal components of the generator.
If using welding equipment on the vehicle, ensure a suitable fire extinguisher is readily available.

Screw Threads

Damaged nuts, bolts and screws must always be discarded. Attempting to recut or repair damaged threads with a tap
or die impairs the strength and fit of the threads and is not recommended.
NOTES:

During certain repair operations, it may be necessary to remove traces of thread locking agents using a tap. Where this
is necessary, the instruction to do so will appear in the relevant operation and it is essential that a tap of the correct size and
thread is used.


New Taptite bolts when used cut their own threads on the first application.

Some bolts are coated with a thread locking agent and unless stated otherwise, they must not be reused. New bolts
having the same part number as the original must always be installed. When nuts or bolts are to be discarded, the
repair operation and relevant torque chart will include an instruction to that effect. Do not use proprietary thread
locking agents as they may not meet the specification required. See also Encapsulated ('Patched') Bolts and Screws.
Always make sure that replacement nuts and bolts are at least equal in strength to those that they are replacing.
Castellated nuts must not be loosened to accept a split pin except in recommended cases when this forms part of an
adjustment.
Do not allow oil or grease to enter blind holes, the hydraulic action resulting from tightening the bolt or stud can split
the housing and also give a false torque reading.
Always tighten a nut, bolt or screw to the specified torque figure, damaged or corroded threads can give a false torque
reading.
Nut and bolt loosening and tightening sequences, where given, must ALWAYS be followed. Distortion of components or
faulty sealing of joints will result if the sequences are not followed. Where an instruction is given to tighten in stages,
these stages must be adhered to; do not attempt to combine stages particularly where certain stages involve
tightening by degrees.
To check or re-tighten a fixing to a specified torque, first loosen a quarter of a turn, then retighten to the specified
torque figure.
Unless instructed otherwise, do not lubricate bolt or nut threads prior to installing.
Where it is stated that bolts and screws may be reused, the following procedures must be carried out:
Check that threads are undamaged.
Remove all traces of locking agent from the threads.

CAUTION: DO NOT use a wire brush; take care that threads are not damaged.
Make sure that threads are clean and free from oil or grease.
Apply the specified locking agent to the bolt threads.
