1.4.4. General information and security measures at control survey and maintenance of the car
At operation of the car inevitably there are such processes as weakening of fastening of knots and units, wear of the rubbing surfaces, violation of adjusting parameters, aging rubber a product and paint and varnish coverings. For the prevention of malfunctions and increase in reliability of the car scheduled preventive maintenance which includes test, adjusting, lubricant works, and also replacement of separate details is provided.
This subsection of the book will help the motorist to support the car in good repair, to reduce operational fuel consumption and oils and to prolong car service life. The general plan of scheduled preventive maintenance of the car is provided in this subsection, the subsections describing maintenance operations in more detail follow further. The drawings of a motor compartment and bottom of a body of the car which are contained in the book allow to gain an impression about an arrangement of basic elements. Carrying out maintenance in strict accordance with the plan provided in the book will provide long and reliable service of the car.
At service of the car you will notice that some operations can be combined. For example, if you lifted the car for carrying out any operation, then can check at the same time elements of system of production of the fulfilled gases. To be prepared carefully for carrying out maintenance. Read the description of operation which you are going to execute, and buy tools and spare parts necessary for this purpose. If you faced a problem which is not able to be resolved independently, address experts.
Regular maintenance will provide:
– good fuel profitability;
– long service life of the car;
– receiving pleasure from driving of the car;
– traffic safety;
– iozmozhnost of use of all advantages of a guarantee;
– compliance to requirements of the current legislation regarding environmental protection.
At non-compliance with instructions and the appropriate measures of safety maintenance of the car constitutes danger. Performance of some operations is connected with risk of heavy traumatizing. If you have no sufficient knowledge and practical experience, or you have no the necessary instrument or the equipment for carrying out work, charge maintenance of the car of the service station of the official dealer of Mazda.
The working engine.
It is dangerous to work in a motor compartment if the engine is not killed. Danger of traumatizing becomes even higher if you wear jewelry or clothes of a free cut. Jewelry, volume or long elements of clothes can get to the rotating details that is fraught with traumatizing. Therefore if it is necessary to perform works in a motor compartment at the working engine, surely take off all jewelry (especially rings, bracelets, hours, chains), and also a tie, a scarf or similar free details of clothes before approaching directly the engine or the fan of cooling which can unexpectedly join and begin to rotate.
Viscosity of engine oil influences fuel profitability and operational properties of the engine at a low temperature (for example, launch of the cold engine). Use of low-viscous engine oil improves toplivnoy profitability and facilitates launch of the engine at low temperatures of air. However, at high temperature of air the use of more viscous engine oil providing the best conditions of lubricant of details of the engine is required.
At the choice of viscosity of engine oil consider the prevailing air temperature range during the period before the following replacement of oil. Then define the recommended viscosity of engine oil by the schedules given above.
The consumption of engine oil is caused, generally by burning out of an oil film on walls of cylinders, combustion of the oil which got to engine cylinders through system of ventilation of a case and losses on evaporation. The natural consumption of engine oil for the serviceable engine makes to 0,8 l on 1000 km of a run of the car. At the beginning of operation of the car when occurs extra earnings of details of the engine, the consumption of engine oil can exceed the specified size. The consumption of engine oil depends on the modes of operation of the engine (frequency of rotation of a bent shaft and loading), and also a manner of driving of the car. At dynamic high-speed style of driving of the car when the engine works in the forced modes, the consumption of engine oil increases and can exceed the size stated above.
