Buying a device is simple, and there are various brands and models of excavators available for sale in major domestic markets. Whether you are buying a new or used excavator, you should know that the maintenance time for an excavator is generally aroundAbout 400-600 hours. If you don't know how to maintain and don't understand some basic maintenance knowledge of excavators, then the only way is to hire a master who understands mechanical equipment to operate, and supervision is needed in between.
Mr. Li from Yunnan purchased a second-hand excavator from Huacheng and had it in good condition for the first three months. However, due to poor maintenance, the excavator experienced a speed drop in the later period. At this time, Mr. Li did not pay enough attention to it. After encountering issues such as car congestion, the maintenance technician hired exaggerated the problem with the equipment, and in the end, Mr. Li spent money on itAfter a few days of use, the problem reappeared for over 20000 yuan. Finally, through Huacheng after-sales service inspection, it was found that the excavator had significant issues with daily maintenance and upkeep. Mr. Li chose the cheapest miscellaneous parts for maintenance accessories, initially just to save some money, but ultimately spent more.
Firstly, regular maintenance should be carried out according to the instructions and maintenance schedule in a planned manner, and original parts must be used for maintenance.
Secondly, in case of minor problems, malfunctions, or damage to parts, it is essential to replace and repair them immediately to avoid unpredictable failures that may cause greater losses and repair costs in the future.
Thirdly, it is common to apply butter, but it is important to regularly check whether the butter nozzle and tube are functioning properly. If the butter tube is not unobstructed, it can lead to increased wear and tear on the entire working surface,
Fourthly, during daily use, it is essential to conduct routine checks on engine oil, hydraulic oil, and management circuits to avoid any deficiencies.
Fifth, it is not advisable to change the oil during the oil change stage if the temperature is too highAt 50 ° C, be patient and wait for the oil temperature to decrease before replacing. When replacing, try to drain as much as possible. At this time, be patient and wait for a period of time until it is completely drained. It is best to use an oil filter for the first filtration.
Sixth, many machine owners may only know how to replace the three filters and engine oil, but the replacement of hydraulic oil is not based on the time provided by the manufacturer. If the working environment of the excavator is harsh and the amount of work is large, the cycle of replacing hydraulic oil should also be shortened. Conversely, the replacement time can be extended.
Seventh, replacing the three filters should be done professionally. Some machine owners have seen the replacement of the three filters once or twice and personally do it. At this time, they need to know some small skills and replacement sequence, especially some air must be completely discharged before replacement to avoid usage problems. Especially for some replacements that require professional tools, if they are not tightened enough or have gaps, it may lead to various mechanical failures.
Eighth, many components of the excavator, such as the walking motor oil and rotating motor, also require lubrication and replacement. It is necessary to purchase original gear oil. Because the replacement time of these oils is not a regular maintenance cycle, they are usually longer and the price is not very expensive. Don't be tempted by small gains and suffer big losses.
