In the hot summer, due to the influence of environmental temperature, it will bring many difficulties to the use of small excavators. For example, the "heart" part of the whole machine, the diesel engine, due to the increase in temperature, the oil viscosity decreases, and the lubrication effect decreases at the same time, which makes the power weak. , The internal parts are also prone to wear, which is a relatively common failure. Therefore, in summer, when doing a good job of maintenance of small excavators, it is necessary to carefully maintain the diesel engine, so that the small excavator can be used safely under the high temperature in summer and it is of great significance to extend the service life of the whole machine.

　　How to use small excavators safely at high temperatures

　　 1. The engine oil and lubricating oils need to be replaced in summer. Check for oil leakage frequently.

　　2. The battery fluid should be replenished in time, the charging current should be appropriately reduced, the aging circuit should be replaced in time, the fuse capacity should meet the requirements for safe use, and the equipment should be equipped with a fire extinguisher.

　　3. Check the water pump fan drive belt. After the belt is used frequently in summer, it will cause fatigue and deformation, which will reduce the cooling effect. When replacing the belt, pay attention to the model and length, and adjust the tightness correctly.

　　4. Frequently check the braking efficiency of the whole machine, so as to find and eliminate the faults in the braking system in time and reduce the hidden danger of accidents.

　　5. Always pay attention to the degree of the water temperature gauge. When it reaches 100 degrees Celsius or above, you need to take timely measures. You can choose to park in the nearby shade and cool down at idle speed. Do not turn off the engine immediately to prevent the engine from overheating and causing a cylinder pulling accident.

　　6. When wading, do not make the small excavator incline more than 15° to avoid immersing the upper structure in the water and damaging the radiator. The track tensioning cylinder should also be tightened frequently to remove the sludge on the cylinder to prevent the cylinder from rusting.

　　7. The summer weather is hot, and the driver is physically exhausted and easily fatigued. It is not allowed to be over-fatigued and over-driving. It is necessary to ensure adequate sleep, so that the work efficiency is higher.

　　 The driver and construction machinery and equipment must be adjusted in time to achieve the best condition and pass the hot summer safely.
