With the advent of winter, the routine maintenance and repair of excavators is particularly important. Recently, about the excavator winter maintenance methods in the network has attracted widespread attention. In this article, we will introduce the three aspects of reducing fuel consumption, maintenance and repair of long-term shutdown, and inspection and maintenance of ERG cooler.

 Key operation to reduce fuel consumption

The key to reducing fuel consumption in winter lies in proper operation and maintenance. Among them, fuel tank drainage and oil-water separator inspection are two important links. In order to avoid damage to the fuel nozzle and pump caused by too much water in the fuel, users need to regularly clean the fuel tank and oil-water separator to ensure the purity of the fuel. Meanwhile, when refueling, attention should be paid to the timely closure of the fuel tank cap to avoid fuel volatilization and pollution. In addition, in order to further improve the combustion efficiency of fuel, users should also pay attention to the selection of high-performance fuel pumps and injectors, and regularly replace the filter element and high-voltage coil. These measures can effectively reduce energy loss and improve the power performance and fuel economy of excavators.

long-term downtime maintenance and maintenance

For excavators that have been down for a long period of time without power, the guide also puts forward corresponding maintenance recommendations. Since the monitor controller may return to its initial settings due to power failure after a long period of non-use, users need to contact their nearest Hitachi Construction Machinery dealer to ensure that the machine's settings are correct. Otherwise, GPS-related functions may not work properly due to incorrect model machine number information. In addition, in order to cope with the severe cold weather in winter, users also need to pay attention to the excavator's preheating and anti-freezing measures. In the low temperature environment of about -30 degrees Celsius, the excavator should be fully warmed up for at least 30 minutes to ensure the normal operation of the machine and extend the service life.

Inspection and maintenance of EGR cooler

In winter, the inspection and maintenance of EGR cooler should not be neglected. Due to the corrosion in winter and fuel with excessive sulfur content, the EGR cooler is easy to attach sulfide and have damage, leakage and other problems. Therefore, users need to regularly check the status of the EGR cooler and replace damaged parts in time. Meanwhile, in order to avoid the lack of antifreeze in case of failure, users also need to pay attention to the addition and replacement of antifreeze.

Through the above, it can be seen that through correct operation and maintenance, users can not only effectively reduce fuel consumption, but also extend the service life of the excavator and improve work efficiency. At the same time, users should also pay attention to the winter cold protection and warmth measures to ensure that in the cold weather can still be normal digging operations.
