   e) Repeatedly justirowka of system of the European parliament. For this purpose you turn a steering wheel at the working support motor before blow.

Check and leaving

In operating time with the battery it is necessary established precautionary measures that they undertook.

In banks of the battery always hydrogen is present at the highest step of ogneopasnyj therefore you do not allow rapprochement to batareje with the lit cigarette or other types of naked flame at all.

elektrolit of the battery submits the solution of sulfur-containing acid which causes serious violations during the meeting on the person or on the open land plots of a body.

Besides, acid gnaws through clothes and colors. At shutdown of the battery always from the first you exclude a weight cable, and you include it in the last row!


You will prepare necessary tools.

Tools and materials which are necessary for leaving of the battery

1 — Persons boards / goggles - during removal from a brush of traces of corrosion of a particle of the crystallizing acid easily can get on the person
2 — it is possible to use soda - the water solution of soda for corrosion neutralization
3 — Beskislotnyj vaseline - is entrusted on clips of the battery the layer of vaseline will help to avoid its corrosion
4 — application for cleaning of clips / tops of lines - will remove such application with a wire brush all traces of corrosion from clips of the battery and tops of lines
Are 5 the Impregnated felt glasses - the device of such glasses on each clip of the battery under tops of lines directly will help to avoid corrosion
6 — if the tiskalshchik appears - sometimes tops of lines very difficult, from clips of the battery to be diminished even after full weakening of Muttern/bolts. This tool will help to accept tops vertically upward without damages
7 — application for cleaning of clips / tops of lines - still type of the cleaning tool, which a little changed version of point 4 which fills the same functions
8 — rubber gloves - still a security measure in operating time with the battery; they remember that acid is in batareje!


 EXECUTION ORDER

1. Leaving of the battery it is necessary to avoid very important procedure, allowing, breaks on the way because of its discharge. For execution of the procedure of service demand the corresponding tool.

3. Cars of this class of batteries which do not demand special leaving are usually equipped. It is possible to be diminished a cover of cans and doliwat distillirowannuju water. Latest models can be equipped with batteries which do not demand at all leaving which are sealed completely.
4. Be lowered covers and check the elektrolita level in each of battery cans. It has to be higher than disks. Usually there is on each can a list of level. If it is lower the elektrolita level as norm, add only distillirowannoj of water and then you are closed covers of cans.

Overpopulation of cans can lead to transfusion of elektrolita during the accelerated shop that will cause corrosion and damage closer to batareje of components!

5. If the positive clip and a collar of the line of the battery of your car of a rubber tire are equipped, be convinced that it is broken it is damaged. It has to close a clip completely.
