12.1. General information and security measures

Cars of these models have the "universal and body" scheme where the floor panel with forward and back side beams (longerons) of a frame playing a role of carriers of other details of a body of the car, forward and back suspension brackets and other mechanical components is used. Wind and back glasses are pasted. Some of components are especially vulnerable at accidents and there can be otbolchena and are repaired or replaced. The cowl, a trunk lid, doors and forward wings concern to them. At installation it is necessary to observe gaps, otherwise, for example, the door will knock or the increased noise from wind at the movement will be observed. The gap has to be, at least, parallel on the extent, i.e. the distance between parts of a body has to be maintained to constants on all length. Tolerances to 1 mm.

In the course of production the body of the car is completely zinced. External elements of a body have an electrodeposited zinc coating as such type of a covering is technological when drawing a paint and varnish covering and is easily deformed. Internal and invisible elements of a body have cheaper hot galvanizing. For increase in corrosion resistance in addition all hollow details of a body are filled with wax, and the sheeting is applied on the bottom. Bumpers and loker of an arch of a wheel for durability and durability are made of plastic.

During the dismantling and assembly try not to put damages to consolidations and the anticorrosive covering put with manufacturer.

Before works with the dashboard, doors or any devices of electric equipment remove a weight wire from the accumulator. For this purpose study remarks in the subsection Removal and installation of the rechargeable battery and the subsection Input of a Code of the Radio Receiver.

Security measures when carrying out body works

– At repair of a body it is necessary to apply spot welding. Only if it is impossible to bring electrodes to the place of welding, it is necessary to apply welding in the environment of inert gases. As the body is completely galvanized, it is necessary to take the following security measures:
– When carrying out the welding works or any other works connected with formation of sparks surely switch-off the rechargeable battery (positive and negative cables) and carefully isolate both plug(s) and (+). When working near the rechargeable battery, it needs to be removed.
ATTENTION

At removal of the battery the memories given from electronic blocks, in particular, a radio receiver code are erased. Without code the radio receiver can be switched on only it by the manufacturer or HUNDRED AUDIS. Therefore read remarks in the subsection Input of a Code of the Radio Receiver.
When welding galvanized sheets poisonous oxide of zinc is formed. Therefore it is necessary to monitor good ventilation of a workplace.
Increase welding current by 10, at most 30%.
Apply electrodes from solid copper with high thermal resistance (above + 400 °C).
Clear electrodes more often and process them to diameter of a contact surface of 4 mm.
Increase pressure upon an electrode.
Increase welding time. Time is chosen truly if welding ends are put without splashes.
The conditioner details filled with a working body cannot be welded and soldered both soft, and solid solder. It belongs also to a situation when there is a danger of heating of elements of the conditioner during the welding or the soldering of other elements of a design.


In addition

It is not necessary to open a contour of cooling of the conditioner since coolant at hit on skin can cause a frostbite.

When drawing a paint and varnish covering in the drying furnace heating of the car up to one temperature higher + 80 °C is not allowed. Otherwise electronic devices of the car can be damaged. Besides, in the conditioner pressure able increases to lead to destruction of system.

– The car bottom sheeting from PHV is removed the rotating steel brush or hot air temperature to + 180 °C by means of the pallet. Owing to heating of a covering from PHV up to the temperature over 180 °C there is a chemical reaction and the hydrochloric acid promoting active corrosion is formed, besides, noxious to health vapors are formed.
