Safety Precautions L —^ ^^—^
Safety Precautions "
All service workshops are a source of potential danger and repair work should only be performed by technically
trained staff following the procedures in this manual. A safety conscious approach to the performance of all service
procedures must be observed at all times. Statutory requirements governing all aspects of health and safety at work
including directives for the proper use of materials and equipment must be implemented.
The following contains a list of particular safety precautions which should be observed; it is not intended to be
exhaustive.
Air Conditioning System
Do not disconnect any air conditioning refrigerant system pipes unless trained and instructed to do
so.
The refrigerant
used can cause blindness if allowed to contact your eyes.
Chemical Handling and Storage
Chemicalsusedintheservicingofmotorvehiclesincludeacids,adhesives, antifreeze, brake fluids, coolants, grease,

oil,
paint, resin and solvents. Exposure to certain chemicals through direct contact or inhalation can be
fatal.

Potential hazards may also be present through the incorrect use, storage and handling of chemicals causing a fire
risk. The following precautions should be observed.

1.
Strictly adhere to handling and safety information found on containers and labels.

2.
Do not store chemicals in unlabelled or incorrectly labelled containers.
3. Containers used for storing chemicals should not be left
open;
there is a risk of
spilling,
or evaporation of fumes
which may be inflammable or toxic.

4.
Do not mix chemicals unless instructed to do so following manufacturers guidelines.
5. Do not inhale chemical materials to determine identity, they may be toxic.
6. Do not use petrol, kerosene, diesel
fuel,
gas oil, thinners or solvents for washing
skin.

7. Containers whose capacity is over 25 litres (5 gallons) require a bund wall in order to contain spillages.
8. Chemicals based on solvents such as paint should not be sprayed in a confined space; work areas used for
such operations should be well ventilated and fume extraction equipment should be utilised.
9. Ensure that adequate ventilation is provided when volatile de-greasing agents are being used.
WARNING: Fume extraction equipment must be in operation when
solvents
are
used
e.g.
trichloroethane, white
spirit, SBP3, methylene chloride, perchlorethylene.
WARNING: Do not smoke in the vicinity of volatile de-greasing agents.

10.
Avoid splashing the
skin,
eyes and clothing.

11.
Clean chemicals from the skin and clothing as soon as possible after soiling.

12.
Wear protective clothing such as goggles, non porous gloves and apron when hand
I
ing battery acid and other
corrosive and toxic substances.

Safety Precautions
Safety Precautions (continued)
Electrical Equipment

1.
Ensure that electrical equipment is in safe working order before use.

2.
Inspect power leads of all mains electrical equipment for damage and security, and check that it is properly

earthed.

3. Ensure that electrical equipment is protected by a fuse of the correct current rating.

4.
Disconnect the battery before commencing repair operations to the electrical system, fuel system and engine
or when working beneath the vehicle.
Exhaust Fumes
Engines should not be run in confined spaces, exhaust fumes contain harmful and toxic substances including carbon
monoxide which can prove fatal if inhaled. Engines must only be run where there is fume extraction equipment in
operation or where there is adequate ventilation.
Fire Precautions

1.
Ensure that a suitable form of fire extinguisher is conveniently located near the work area.

2.
Keep oils, solvents and combustible materials away from naked flames and other sources of ignition.
3. Ensure that NO SMOKING signs are posted around areas where combustible materials and vapour may be
present and ensure that the warnings are strictly observed.

4.
Ensure that dry sand is available to soak up any spillage of fuel or other flammable solutions.
5. Fume extraction equipment must be available and in full working order to remove combustible and toxic
vapours.
6. All personnel should be aware of the fire drill procedures and precautions.
Jacking and Lifting

1.
The recommended procedures for lifting, jacking and towing are included latefin this seetion-and must be
strictly observed to ensure personal safety.

2.
Always use a vehicle hoist, ramp or pit for working beneath the car in preferencetd^&^cking
3. Never rely on a jack to support a car independently, use axle stands or blocks carefully pJaQed at the jacking
points to provide rigid support.

4.
When working beneath a vehicle, chock the wheels as well as applying the handbrake.
5. Ensure that the vehicle is standing on firm level ground before jacking or lifting.
5. Check any lifting equipment used has adequate capacity for the load being lifted and is ih"fdll working order.
Tools and Equipment

1.
Do not leave tools, equipment, spilt oil, etc. around or on the work area.

2.
Ensure that tools and equipment used are in good condition; do not use damaged or defective tools or
equipment.
3. Do not apply heat in an attempt to free stiff nuts or fittings; as well as causing damage to protective coatings,
there is a risk of damage to electronic equipment and brake lines from stray heat.

4.
Use the recommended service tool where instructed to do so.

The Aston Martin Lagonda Diagnostic System
Installation Instructions ^=2?
Warranty
The Aston Martin Diagnostic System is covered by a one year warranty. Should any of the electrical components
fail during the warranty period, contact your local GenRad Service Centre for a replacement part. Note that the
warranty does not include physical damage.
Spare Parts
Refer to the Aston Martin Diagnostic System Users Guide for a full parts list. All spare parts should be obtained from
your local GenRad Service Centre who can advise you on current prices.
Servicing and Maintenance
CA UTION: With the exception of those parts listed in this section, there are no user serviceable parts within the
system. All servicing must be carried out by GenRad Service Centres.
Battery Testing.
The NICAD batteries fitted in the PDU are designed to be rechargeable and should normally last through many
recharge cycles. Battery life of three to five years can be expected. The capacity of new batteries improves after
several charging cycles. After extended use, they may require renewing. The following procedure will assist you to
determine when renewal is required. Do not use this procedure with new batteries or with a new PDU.
Testing Procedure

1.
Remove all cables from the PDU.

2.
Switch the PDU on and leave it until it switches off (the power on indicator will extinguish)
3. Connect the PDU to the base station for at least 12 hours charging.

4.
Remove all cables from the PDU, switch on the PDU and start timing.
5. If the PDU switches off in less than 30 minutes, the batteries should be renewed.
Changing the Battery Pack
CAUTION: Always read and follow safety warnings and instructions printed on the equipment. The rechargeable
NICAD batteries fitted to the PDU are of a special type. They must only be substituted by GenRad approved parts.
Do not substitute the batteries with any other type. Always dispose of old batteries in compliance with local
recycling regulations.
Battery Changing Procedure
A spare battery pack kit (0975) is available from your local GenRad Service Centre.
