1.4. Maintenance of the car

In use the car there is a deterioration in its technical condition owing to wear of the rubbing surfaces of details, violations of adjusting parameters, aging of rubber products and other phenomena. For the prevention of malfunctions and increase in service life of the car it is exposed to scheduled preventive maintenance which includes lubricant, check and adjustment of knots of the car through a certain run. Frequency of maintenance and the name of works are given in tab. 1.2.

Regularly through each 500–600 km of a run (or before each departure) check oil levels in a case of the engine, cooling liquid in a broad tank, brake fluid in a tank of a hydraulic actuator of brakes, electrolyte in the rechargeable battery, and also air pressure in tires.
Oil level in a case of the engine needs to be checked on the cold idle engine. Level has to be between risks "MIN" and "MOVE" of the index.
Replacement of oil is made on the warm engine. For discharge of the fulfilled oil it is necessary to turn off a stopper in the case pallet.
The oil filter is changed, having turned off it from the block of cylinders. Before installation of a new oil filter its sealing ring is oiled engine. The new filter is wrapped to a contact of a sealing ring of the block of cylinders, and then by effort of hands dovorachivat it on 3/4 turns.
Level of brake fluid at the established cover and new overlays of brake mechanisms has to reach the lower edge of a jellied mouth.
At the same time it is necessary to check serviceability of operation of the sensor of emergency level. For this purpose it is necessary to press from above the central part of a protective cap. At the same time in a combination of devices the control lamp has to light up if ignition is included.
The control alarm lamp of critical condition of the working brake system lights up when liquid level in a tank fell below a tag of "MIN" that at partially worn-out or new overlays of blocks of brake mechanisms speaks about loss of tightness of system and about liquid leak. Dolivka of liquid in this case is carried out only after restoration of tightness of system.
If the hydraulic actuator of brakes is serviceable, lowering of the level of liquid in a tank is connected with wear of overlays of blocks of brake mechanisms. Lowering of the level of liquid to a tag of "MIN" indirectly testifies to their extreme wear. In this case it is necessary to conduct direct control of a condition of blocks.
Checking technical condition of brakes, previously clear forward and back brakes of dirt, wash out warm water and dry up compressed air. It is not allowed to apply at the same time any mineral solvents as they can cause damage of protective caps and sealants of hydraulic cylinders.
The polluted overlays of blocks, disks and drums clear a metal brush and wash out detergents. If on slips traces of brake fluid are found, it is necessary to find and remove the causes of its emergence. In maintenance time preserve brake shoes, disks and drums against hit on them of oil or lubricant.
Level of cooling liquid in a broad tank has to be always 25-30 mm higher risks of "MIN". You carry out check of level and opening of a stopper of a tank for a dolivka of liquid only on the cold engine. After a liquid dolivka the stopper of a tank has to be densely wrapped as the broad tank at the working and heated-up engine is under pressure.
As a last resort it is possible to add clear water to the cooling system. But at the same time temperature of freezing of mix increases and corrosion resistance of an aluminum radiator decreases. Therefore at the first opportunity it is necessary to execute repair of system and to fill in in it cooling liquid.
Check of level and density of electrolyte in the rechargeable battery is described in subsection. "Rechargeable battery".
Air pressure in tires, including a spare wheel, is checked by the manometer. We recommend to check periodically the manometer at the enterprise of maintenance.
If continuous pressure drop of air in the tire is observed, check by means of soap solution whether there is no leak of air through a gate zolotnik. In case of leak of air tighten a zolotnik a key on the end of a cap and if it does not help, replace it new.
If pressure falls at a serviceable zolotnik, then using the special sealant enclosed to the car repair the tire.
To avoid damages of the pressurizing tire zakraina layer, dismantle and it you install by means of special adaptation or on the tire machine in repair shop.
Not to break balancing of a wheel, before a razbortovka make a mark chalk on the tire against the gate, and at installation install the tire on this tag.
After installation of new tires surely balance wheels at the enterprise of maintenance.
At operation of the car with tubeless tires avoid grinding of wheels to borders of roads and bystry driving on roads with the broken covering (hollows, potholes, etc.) as damage of a rim of a wheel can cause loss of tightness of the tire and an imbalance of a wheel. At emergence during the movement of vibrations it is necessary to check balancing of wheels.
