Before carrying out welding and other work during which sparks are formed, the battery must be completely disconnected (positive and negative wires) and both of its poles (+) And (-) carefully sealed with duct tape. When working near the battery, it must be removed.
Attention: Strictly follow the instructions given in chapter «Removing and installing the battery».
Safety instructions
When performing body work, jolts often occur, for example, when hitting with a hammer. Therefore, the ignition must always be turned off and the wires from the battery terminals disconnected, otherwise the airbag assembly may be deployed. Read the safety precautions for handling the airbag assembly, see p. 117.
Vehicles with air conditioning:Do not weld or solder parts of a filled air conditioning system. This also applies to welding and soldering on the vehicle, where there is a risk of heating parts of the air conditioning system.
Safety instructions
Do not open the refrigerant circuit of the air conditioning system, as contact with the skin may cause frostbite. In case of accidental contact of the refrigerant with the skin, rinse the contact area with cold water for 15 minutes. The refrigerant evaporates at ambient temperature. The refrigerant is colorless, odorless and heavier than air. Since the presence of refrigerant is not felt, there is a risk of suffocation when working near the floor and in the installation pit.
Drying paintwork:when repairing the paintwork, it is allowed to heat the car in the drying chamber or in the area in front of the chamber to a temperature not exceeding +80°C. Otherwise, the electronic control units of the car fail. In addition, a very large pressure arises in the air conditioning circuit, under the influence of which the circuit may burst.
Removing PVC floor covering (PVC): as protection against corrosion, a polyvinyl chloride coating is applied to the bottom of the body. At the place of repair, remove the PVC coating with a rotating steel brush or use a heat gun to heat this area to a temperature not exceeding +180°C and remove the coating with a spatula.
Attention: If the PVC coating ignites or overheats to temperatures above +180°C, highly corrosive hydrochloric acid is formed and, in addition, harmful fumes are emitted.
