Practical Troubleshooting Skills for Used Excavators: Solve Small Faults Independently

Shanghai Fanzeng Engineering Machinery Co., Ltd. – When operating used excavators, encountering small faults is a common situation that may cause troubles for operators. Many customers tend to feel anxious when facing such problems and rush to arrange professional maintenance, which not only increases additional maintenance costs but also delays the progress of engineering operations. To help customers reduce costs and improve work efficiency, Shanghai Fanzeng Engineering Machinery specially shares two practical and easy-to-operate troubleshooting skills for common small faults of used excavators, enabling customers to troubleshoot and solve problems independently.

Shanghai Fanzeng Machinery emphasizes that customers do not need to panic when encountering small faults during the use of used excavators; most minor issues can be easily resolved through simple inspections and operations. The two common fault troubleshooting skills are as follows: First, if the used excavator fails to start normally, the primary step is to check whether the storage battery has sufficient power. Insufficient battery power is one of the most common causes of startup failure, and the problem can be effectively solved by charging the storage battery to the standard power level. Second, if abnormal noise occurs during the operation of the excavator, it is recommended to check two key points: whether the engine oil is at the standard level and whether the connecting parts of each component are loose. A simple visual inspection and oil level check can quickly locate the root cause of the abnormal noise, laying a foundation for timely resolution.

As a professional supplier focusing on the sales of used construction machinery, Shanghai Fanzeng Engineering Machinery mainly provides cost-effective low-priced used excavators, motor graders and bulldozers. All equipment sold by the company has undergone rigorous multi-procedure professional inspections by senior engineers with rich industry experience, ensuring stable performance and reliable quality, and effectively reducing the occurrence of small faults during use. The strict quality control system not only guarantees the service life of the equipment but also reduces the subsequent use and maintenance costs for customers.

In addition to providing high-quality used equipment, Shanghai Fanzeng Engineering Machinery also takes the initiative to provide customers with guidance on simple fault troubleshooting skills after sales. For each customer who purchases equipment, the company will systematically teach relevant troubleshooting methods and daily maintenance knowledge, enabling customers to independently solve common small faults during subsequent use without spending extra money on professional maintenance services. This humanized service further enhances the cost-effectiveness of equipment procurement and brings a more worry-free use experience to customers — a commitment backed by the company’s long-term accumulation of professional strength and rich industry experience in the field of used construction machinery export.
