General information and security measures

GENERAL INFORMATION

Cars of these models have the "universal and body" scheme where the floor panel with the forward and back lateral 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 failures both can be отболчены and are repaired or replaced. The cowl, a trunk lid concern them, doors and forward wings. At installation it is necessary to observe gaps, otherwise, for example, the door will knock or the increased noise from a wind will be observed at movement. The gap should be, at least, parallel on the extent, i.e. the distance between parts of a body should 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 electrolytic zinc covering 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 tsinkovaniye. For increase of corrosion firmness in addition all hollow details of a body are filled with wax, and the sheeting is put 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 the beginning of works with the dashboard, doors or any devices of electric equipment remove a weight wire from the accumulator. For this purpose familiarize with remarks in the subsection Removal and installation of the storage battery and subsection Input of a code of a radio receiver.

Security measures at 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 a place of welding, it is necessary to apply welding in the environment of inert gases. As the body is completely zinced, it is necessary to accept the following security measures:
– At carrying out welding works or any other works connected with formation of sparks, surely disconnect the storage battery (positive and negative cables) and carefully isolate both plugs (–) and (+). At works near the storage battery, it is necessary for removing.

ATTENTION

At removal of the battery the memories given from electronic blocks, in particular, a radio receiver code are erased. Without a code the radio receiver can be included only by his manufacturer or HUNDRED AUDIS. Therefore read remarks in subsection Input of a code of a radio receiver.
When welding the zinced sheets poisonous oxide of zinc is formed. Therefore it is necessary to watch good ventilation of a workplace.
Increase a welding current by 10, at most 30 %.
Apply electrodes from firm copper with high thermal firmness (above + 400°С).
Clear electrodes more often and process them till diameter of a contact surface of 4 mm.
Increase pressure upon an electrode.
Increase welding time. Time is chosen truly if welding points are put without splashes.
The details of the conditioner filled with a working body, it is impossible to weld and solder both soft, and firm 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 the coolant at hit on skin can cause frostbite.

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

– The sheeting of the bottom of the car from PHV is removed a rotating steel brush or hot air in temperature to + 180°С by means of a shpatel. Owing to covering heating from PHV to temperature over 180 ° With there is a chemical reaction and the hydrochloric acid promoting active corrosion, besides, is formed unhealthy pairs are formed.
