Customer Background: A car repair shop in Texas, USA, purchased a 4-post 4-ton car lift from us. After the on-site installation was completed by the customer’s team, they encountered a critical issue: the lift failed to lift normally, which affected the shop’s daily operation and caused great inconvenience. The customer contacted our after-sales team immediately for urgent support.
After-Sales Response: First-Time Remote Video Troubleshooting
Upon receiving the customer’s call, our 24-hour after-sales team responded within 15 minutes, fully understanding the problem: the lift could not lift any vehicle after installation, and there was no abnormal noise or warning signal. Considering the urgency of the customer’s business and the long distance, we proposed a remote video troubleshooting solution immediately—arranging a senior after-sales engineer proficient in English to connect with the customer via Zoom, to find the root cause in real time.
The customer agreed quickly, and our engineer initiated the video call on time, adapting to the customer’s time zone to ensure smooth communication. During the call, our engineer maintained a patient and professional attitude, guiding the customer to operate the lift step by step, and carefully observed every part of the equipment through the video, including the hydraulic system, control panel, and connecting parts.
Root Cause Identification: Incorrect Hydraulic Oil Pipe Specification Installation
In the process of remote guidance, our engineer first communicated with the customer in detail about the installation process and steps, asking about the connection method of the hydraulic system, the installation sequence of parts, and whether the installation personnel referred to the English operation manual. Through the customer’s description and real-time video observation, our engineer found that the hydraulic oil pipe installed by the customer’s team did not match the specified specification of the lift.
We explained to the customer clearly: the 4-post lift requires a specific model of hydraulic oil pipe to ensure sufficient oil pressure for normal lifting. The oil pipe installed by the customer was of a smaller specification, which led to insufficient oil flow and pressure in the hydraulic system, making it impossible to drive the lift to rise. At the same time, we showed the customer the correct oil pipe specification and installation standard through the video, comparing it with the incorrectly installed oil pipe to let the customer understand the problem intuitively.
Solution Implementation: Professional Guidance & Timely Support
After confirming the root cause, our after-sales team immediately formulated a solution and communicated it to the customer in detail: first, we sent the correct specification of hydraulic oil pipe to the customer via express delivery (with a guaranteed delivery time of 3 working days to Texas), and provided a detailed English installation guide video and step-by-step text instructions.
During the waiting period for the oil pipe, our engineer conducted another video call to re-explain the correct installation process of the hydraulic system, emphasizing the key points of oil pipe connection, sealing and pressure testing, to avoid the same problem in the second installation. We also answered all the customer’s questions about the installation, such as how to check the oil pipe tightness and how to test the hydraulic pressure after installation.
After the customer received the correct oil pipe, our engineer connected with the customer again via video, guiding the installation team to replace the oil pipe step by step, and conducting a full test after installation. When the lift successfully lifted the vehicle smoothly, the customer expressed great satisfaction with our efficient and professional after-sales service.
After-Sales Follow-Up & Prevention Measures
After the problem was completely solved, we followed up with the customer 3 days later to confirm the normal operation of the lift and ask if there were any other usage problems. We also sent a detailed after-sales maintenance manual to the customer, reminding them of the daily inspection points of the hydraulic system and the replacement cycle of vulnerable parts such as oil pipes.
To avoid similar problems in the future, we optimized our pre-installation service: before the customer starts installation, our team will conduct a pre-installation video guidance, emphasizing the key parts and specifications of the equipment, and providing one-on-one consultation for the installation personnel.
| After-Sales Concept: We understand that any equipment failure will affect your business. Our after-sales service is not just about solving problems, but about providing timely, professional and thoughtful support—from remote troubleshooting to on-site guidance, we are always with you to ensure your car lift operates stably. |
