How to maintain a tractor?
According to the engine compression right than the gasoline octane number, can not use the special symplectic low octane number, pay attention to the normal temperature to keep the engine, postpone the ignition advance angle and add rich mixture, at the same time, should be timely for the removal of coke combustion chamber, valve top parts in total. In addition, the car before loading uphill should choose moderate grade, keep the power is good, in order to prevent excessive refueling, or adjust the carburetor main oil needle, make mixture slightly dilute, etc, can effectively prevent deflagration.
Clean the gasoline filter, fuel tank and oil duct to keep it clean and clear. Check and adjust the gasoline pump working pressure, keep the normal, once the gas resistance, should stop cooling, open the carburetor inlet pipe joints, the gasoline pump rocker arm, make full recovery of the normal supply of gasoline oil. In order to prevent the fuel system of air resistance, usually by cold cooling, the oil supply is smooth; the installation of insulation pad, gasket asbestos board is additionally arranged between the cylinder and the gasoline pump, reduce the engine to the petrol pump heat, prevent air resistance. In addition, the use of electric gasoline pump is an effective way to prevent air resistance.
Into the high temperature season, we should pay attention to the correction of the proportion of electrolyte, the ratio is more important than in winter, and at the same time, often check the battery surface height, timely supplement distilled water, and keep the ventilation hole open. In order to prevent the excessive consumption of electrolyte due to the high temperature, the generator regulator needs to be adjusted to reduce the charging air flow of the generator.
Prevent braking failureHydraulic brake vehicles, to check the master cylinder, replacement of brake oil, brake pipe air drained thoroughly, and check and adjust the brake pedal height, air braking vehicle, must pay attention to the good procedure to check the brake cup and brake hose, found damaged should be replaced in time.
When the automobile is running under the condition of high temperature, because of the high temperature outside, the heat dissipation of the tyre is slower, and the air pressure is correspondingly increased, and the tyre explosion is easy to occur. Therefore, in high temperature conditions, the operation should pay attention to the temperature and pressure of the tire, check regularly, and ensure the standard of air pressure. If you find that lack of gas should be made up in time, absolutely can not improvise. Long distance running car, speed should be reduced, if necessary, parked in shady locations, so that the tire temperature decreases and then continue to run, must not be poured cold water to reduce tyre temperature, such as tread and sidewall layer of each part of the uneven shrinkage and crack.
