What should you pay attention to when maintaining machinery in summer?

Excavators will cause various malfunctions due to high temperatures during operation. If you want to reduce malfunctions during daily work, you should remember the following tips:

1. Observe the water temperature meter at any time to prevent water shortage: 

When working in high temperature weather, always check the cooling water volume and pay attention to the water temperature meter. Once it is found that the auxiliary water tank is short of water, immediately idle it to cool down and then add water. Be careful not to open the radiator cover immediately to prevent burns.

2. The engine oil prevents deterioration：

The lubricating oil will become thinner when heated, and the viscosity will decrease, resulting in a decrease in lubrication performance. It is also prone to deterioration, resulting in poor oxidation resistance, which may cause failures such as burning tiles and holding the shaft. Therefore, the engine should be replaced with special summer lubricating oil, the lubricating oil level and oil quality should be checked frequently, and replaced in time.

3. Clean the oil on the surface of the engine in time:

 If the oil on the outside of the engine is too thick, it may affect heat dissipation and create hidden dangers for the failure of various parts. You can use high-pressure injection to clean the engine parts with a cleaning agent that does not corrode the body parts. Note that the electrical wiring harness is sprayed directly, which may easily cause a short circuit failure. 

4. Prevent the water temperature of the water tank from being too high:

In hot weather, the water tank of the excavator is prone to high temperatures. You need to pay attention to the following points during work:

1. Replace SANY pure antifreeze regularly according to maintenance nodes;

2. Clean the inside and outside of the water tank regularly to ensure that the water tank is clean and smooth;

3. Install insulation cotton around the water tank to prevent hot air from flowing back;

4. Adjust the tension of the engine fan belt to ensure that the fan speed is normal.
