In today's construction industry, as a key equipment, the stable operation of excavator is directly related to the progress and safety of the project. In order to effectively prevent the failure of excavators, prolong the service life of equipment and improve operation efficiency, the newly released daily maintenance guide for excavators provides comprehensive and detailed maintenance suggestions for the majority of excavators.

The operator needs to pay attention to the state of the air filter element every day, and check, clean or replace it regularly to ensure that the engine air intake is unimpeded. At the same time, the internal cleaning of the cooling system has also been put on the agenda. It is suggested that after the engine is completely cooled, the internal pressure of the water tank should be released in strict accordance with the operation rules, and then the water and cleaning work should be carried out to prevent the safety risks brought by the high temperature and high-speed rotating parts under the heat engine state.

As an important walking part of excavator, the tightness and bolt fastening of crawler directly affect the stability and safety of equipment. The maintenance guide details how to check and adjust the track backtension, as well as the tightening standard of the track plate bolt, to ensure that the excavator can be flexible in complex terrain. In addition, the timely replacement of bucket teeth and the accurate adjustment of bucket clearance can not only improve the mining efficiency, but also reduce the wear of components and extend the service life.

In addition to the maintenance of mechanical components, the inspection of electrical systems can not be ignored. It is mentioned in the guide that before starting the engine, the liquid level position of coolant, oil, fuel and hydraulic oil should be thoroughly checked and supplemented as needed to ensure the normal operation of the engine and hydraulic system. At the same time, the inspection of key components such as wires, horns and oil-water separators is also the focus of daily maintenance. Although these details are small, they can greatly improve the overall performance and safety of the excavator.

It is worth mentioning that the maintenance guide also specially emphasizes the cleaning and maintenance of the cab, including cleaning the floor of the cab, checking and supplemting the front window cleaning fluid, as well as the adjustment and maintenance of the air conditioner, which creates a more comfortable and safe working environment for the machine. In addition, for the optional breaker filter element, it also gives clear replacement and cleaning recommendations to ensure the stability of the additional equipment.
