During the hot season, tractors are prone to failure and human-machine damage and casualties occur. So, how to use the tractor properly in the hot season? Let's talk about the experience of the pilots. 1, the high temperature easy to make the water tank, causing the engine to overheat, improper handling will explode cylinder head, cylinder liner. The correct way to deal with this problem is to stop the machine. When the water temperature drops to 60°C to 70°C, add clean cold water to the tank. In order to prevent the engine from overheating, the load of the tractor in the hot season should be controlled at about 90%. 2. When the high temperature season arrives, the oil should be turned from the beginning of the winter to the “summerâ€. After the oil from the filter is cooled by the oil radiator, it will enter the main oil passage to prevent the oil from overheating and burn the tiles. Pull the cylinder. 3, high temperature season, large temperature difference between day and night, easy to cause puncture. For this reason, inflating tires in the morning should be 5%-7% lower than in winter; when inflating tyres at noon, they should be 2%-4% lower than in winter. 4. After the belt is exposed to high temperatures, the tension tends to loosen and slip, causing the engine to overheat and the belt to be damaged. For this reason, in the hot season, check and adjust the tension of the belt to prevent the belt from slipping. 5, high temperature, the battery will produce a lot of water vapor, plug the vent hole, causing the battery internal pressure is too high and burst. For this reason, during the hot season, the pilots should often clear the ventilation holes. 6, high temperature easy to make battery pole pile oxidation, causing locomotive start difficult, electrical system failure. For this reason, the operator should apply butter or vaseline to the poles to prevent the pole stakes from oxidizing. If the pole has been oxidized, the battery cable can be removed from the pole pile, and the oxide layer can be ground with an emery cloth or a saw blade, and then clamped securely. 7, high temperature can also cause the battery water to evaporate, cause water shortage, accelerate the pole pile vulcanization and damage. To this end, every 7-10 days, the operator should check the battery once, if it is found that the liquid level drops, add distilled water in time. 8, the high temperature easy to make the electric horn contact oxidation, issued a continuous rasping sound. At this time, the operator can grind the contacts with emery cloth, and the rasping sound can disappear. 9, rainy season in high temperature, rain into the air filter, easily lead to the tractor "speed." If the engine operator hears a squeaking noise from the engine, it is a sign that the tractor will “flyâ€.
