LNZ will send senior trainers to explain to equipment maintenance personnel the correct use and precautions of the equipment, emergency response methods and equipment maintenance methods.

The company's after-sales service personnel regularly visit the equipment to check the operation of the equipment, perform maintenance and repairs on the equipment, and immediately resolve any problems found and report the specific situation to the company's customer service department.

We have a strict quality management system that evaluates and monitors engineer maintenance response time, fault resolution time, spare parts delivery time, and customer service satisfaction, ensuring high-quality after-sales service.

During the warranty period, fault reports will be responded to within 10 minutes, a technician will respond within 30 minutes, a solution will be formed within 4 hours, and if the problem cannot be solved remotely, we will arrive at the site within 24 hours. All actions will ensure the normal operation of the equipment and there is no possibility of damaging the product.
