NEVA MB-2-assembled equipment for the walk-in tractor

The tractor for walk behavior is convenient and easy to use and wait. With work, no special training is required, but if you use specific stored or follo w-up tools, certain skills are required that you acquire under the instructions for the operation of these tools and for further work with you. The manufacturer of NEVA Motobobloks “Neva” CJSC Krasny Octyabr-Neva is constantly developing new types of additional devices that are intended to expand the possibilities of the motoblock you have acquired.


Use clean, fresh unhealthy gasoline with a shelf life of no longer than 30 days. Do not mix a fuel with butter. It is not recommended to fill petrol under the upper wall of the tank. It should remain a free space above the fuel that is required for the additional volume if gasoline is expanded. This is possible if you work in a walk behavior tractor at high positive outdoor temperatures.

Motor oil engine oil is classified after two parameters: viscosity and quality. The SAE standard classifies the viscosity of oils in conditional units from 0 to 100. It occurs: – Summer (e.g. is a letter “W”, for example 10W30) for use at temperatures under plus 4 0C. The API standard classifies the quality of the oil in operational properties for petrol engines as: SA, SB, SC, SF, SG, SH, SJ.

The first letter S shows that this oil is used for petrol engines. The initial letter C shows oil for diesel engines. In order to designate general oils, i.e. those that can be used to lubricate petrol engines and diesel engines, double marking, such as SF/CC, SG/CD. In all cases, the closer the second letter at the beginning of the English alphabet, the lower the operational properties of the oil. Select an oil viscosity class (summer or winter), depending on the temperature of the surrounding air during the operation of the tractor of the walk behavior (see table).
