In order to ensure that the cooling system of the small whole machine has a good performance, before entering the summer, all parts of the cooling system should be cleaned, tightened and lubricated, and the scale of the cooling system, including the scale in the radiator, should be cleaned as much as possible to improve the heat dissipation efficiency. , keep the cooling system smooth and accelerate the circulation of cooling water
Check the water pump-fan drive belt. After the belt is used for a long time, the belt will be fatigued and deformed, which will reduce the cooling effect. When replacing the belt, pay attention to the model and length, and adjust its tightness correctly
Check the connection hose of the water tank. The oil resistance of the hose of the water tank is relatively poor, and it is easy to be damaged early, thus affecting the water supply and causing the engine temperature to rise too high. Check for cracks and leaks, and remove them in time. At the same time, it is necessary to maintain a sufficient amount of cooling water, and if it is found to be insufficient, it should be added in time
For the correct use of the whole machine, always pay attention to the reading of the water temperature gauge, and take measures when it reaches above 90°. You can choose to park in the nearest shade and cool down at idling speed. Be careful not to turn off the engine immediately to prevent the engine from overheating and causing accidents such as cylinder pulling. After the temperature has dropped, you should also check the tension of the fan belt
Before entering the summer, it is necessary to conduct a performance test on each component of the lubrication system, so that the oil pressure gauge and the gearbox pressure gauge can indicate accurately. Carry out a systematic inspection of the oil in the gearbox, pitch converter and drive axle, from the quality of the oil to the quantity of the oil, and keep the oil clean. Small loaders are maintained in summer. During summer driving, the number of tire layers of small loaders is about 14 layers. Compared with large tires, the heat transfer is faster, and it is easy to overheat the tires, which increases the internal pressure and reduces the physical properties of the tire's rubber. , so as to cause a tire blowout. If you find that the tire pressure and tire temperature are too high, you should park the car in a cool place to cool down before continuing to drive. It is not allowed to depressurize the tire by deflating it, or pour cold water on the hot tire.
