Battery Disconnection

All service workshops are a source of potential danger and repair work should only be performed by technically trained staff following procedures detailed 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 headings highlight particular safety precautions which should be observed (The list is not intended to be exhaustive).

Battery Disconnection

Where a procedure requires the vehicle battery to be physically disconnected (disconnect the vehicle battery earth (Negative) lead), the following items will have to be reset or re-learnt on connection:

• Seats memory
• Radio pre-sets
• DTCs will be lost

Air Conditioning (A/C) System

Do not break into the A/C refrigeration system until the refrigerant has been evacuated using the procedure detailed in this manual. Do not disconnect any A/C refrigerant system pipes unless trained and instructed to do so. The refrigerant used can cause blindness if allowed to contact your eyes.

Chemicals used in the servicing of motor vehicles include acids, 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.

Warning !
Containers whose capacity is over 25 litres (5 gallons) require a bund wall in order to contain spillages.

Warning !
Avoid splashing the skin, eyes and clothing.

Warning !
Ensure that adequate ventilation is provided when volatile de-greasing agents are being used.

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

Warning !
Wear protective clothing such as goggles, non porous gloves and apron when handling battery acid and other corrosive and toxic substances.

Warning !
Do not smoke in the vicinity of volatile de-greasing agents.

Warning !
Fume extraction equipment must be in operation when solvents are used e.g. trichloroethane, white spirit, SBP3, methylene chloride, perchloroethylene.

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

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

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

Warning !
Disconnect the battery before commencing repair operations to the electrical system, fuel system and engine or when working beneath the vehicle.

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

Warning !
Do not store chemicals in unlabelled or incorrectly labelled containers.

Warning !
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.

Warning !
Do not mix chemicals unless instructed to do so, following manufacturers guidelines.

Warning !
Do not inhale chemical materials to determine identity, they may be toxic.

Warning !
Do not use petrol, kerosene, diesel fuel, gas oil, thinners or solvents for washing skin.

Warning !
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.
